Installing LiftTokens

• PHP
• WordPress
• Cloud

To install LiftTokens on your server follow the steps below:

• Open the zip file lifttokens 1.2.3.zip and extract the folder in a server location of your choice.
• Navigate to the link https://[your-site]/lifttokens/admin.php and complete the installation. Replace [your-site] with your website URL. If you changed the directory name, replace lifttokens with the new directory name.
• Once the installation is complete, log in with the username and password entered in the previous step and save the addresses of your cryptocurrency wallets in Settings > Cryptocurrency addresses. Mind that some cryptocurrency require an API key or a node to work, more details here.
• If you are using an integration, complete the installation as explained here.
• You are done! You can start creating your first checkout.

Minify JS

For performance reasons, you may want to load the minified client.js file: [YOUR-URL]/js/client.min.js. Please note that if you contact us for support you will need to load again the non-minified version.

Site migration

If you migrate the script to a new domain or URL you need to edit the config.php file (it's in the LiftTokens folder) and update the LFT_URL constant with the new URL.

---

To install LiftTokens on WordPress follow the steps below:

• Go to the Plugins page and click Add new then Upload plugin and upload the zip file lifttokens 1.2.3.zip.
• Once the installation is complete you should see a new left menu item named LiftTokens.
• Save the addresses of your cryptocurrency wallets in LiftTokens > Settings > Cryptocurrency addresses.
• If you are using WooCommerce complete the installation as explained here.
• If you are using Easy Digitial Downloads complete the installation as explained here.
• If you are using an integration, complete the installation as explained here.
• You are done! You can start creating your first checkout.

The cloud version requires no installation. You just have to copy and paste the embed code, or you can use the direct payment link. If you include multiple checkouts on the same page, please note that you only need to include the <script id="lifttokens" src="https://cloud.lifttokens.com/js/client.js?cloud=MVdDMnZXe..."></script> script code portion of the embed code once.

• If you are using WooCommerce complete the installation as explained here.
• If you are using Easy Digitial Downloads complete the installation as explained here.
• If you are using a integration, complete the installation as explained here.

Whitelist

To increase the security of LiftTokens you can create a whitelist of approved cryptocurrency addresses. Checkout addresses and any transfer of funds will be blocked if the address is not whitelisted. To create the whitelist, edit the config.php file in the LiftTokens installation directory and add the constant define('LFT_WHITELIST', []). The value must be an array containing all the addresses saved in Settings > Cryptocurrency addresses, e.g. define('LFT_WHITELIST', ["bc1qnggf72xfeh8as54", "DEqc4RNjKOdkl0xHH"]).

• This security measure is not required if you are using the cloud version.
• Once the constant is declared, all addresses from Settings > Cryptocurrency Addresses must be included.
• This security check is skipped for the checkout address if the address is dynamically generated via Gemini, Coinbase, Custom explorer or other functions.
• The address verification is performed in the following cases: to verify the checkout payment address, to verify the address of a transfer on your wallet.
• If the address verification fails, an error will be displayed in the browser console.
• Address verification fails if the address saved in Settings > Cryptocurrency addresses is not found in the LFT_WHITELIST constant.

Required API keys and Nodes

The following cryptocurrencies require an API key or a node to work.

• XRP You need a Blockdaemon API key. Enter the key in Settings > API keys.
• BNB You need an openexchangerates.org API key. Get the key from https://openexchangerates.org. Enter the key in Settings > Open Exchange Rates App ID.
• SOL You need a Solana node. Enter the node information in Settings > Solana node. More details here.
• XMR You need to save your Monero secret viewkey in Settings > Monero secret viewkey. For more details about Monero click here.

Requirements

• Your web project must support HTML and PHP, and pages containing a checkout must be opened via a web browser.
• You cannot display the checkout on a HTML page opened directly on a local computer. Use a local server like Xampp instead.
• Your server must allow the access of the following file: lifttokens/ajax.php
• If you're using the WordPress version of LiftTokens and you have any security plugins installed, please make sure that they don't block the lifttokens/ajax.php file.
• PHP 7.4+
• The following PHP extensions are required: CURL, ZIP ARCHIVE, GD extension.
• The following PHP extensions are optional but some optional LiftTokens feature requires them: GMP.
• MySQL - The SQL mode "ONLY_FULL_GROUP_BY", and the setting "ANSI_QUOTES", must be disabled.
• PHP modules: gmp, zip archive, cors. All required PHP modules should already be active by default.

Creating your first checkout

Information

• To understand how LiftTokens detect the payments see the address generation section.
• The checkout page should not be closed before the payment is completed. If it's closed, the cron job function will still check payments but you should set it to run from your server, more details here.

Activation

To activate the LiftTokens and enable all features (including updates and more secure encryption), you need to enter the LiftTokens purchase code in Settings > LiftTokens purchase code.

Updates

• To update LiftTokens, click the button Settings > Updates > Update now.
• You can also activate automatic updates via Settings > Updates > Automatic updates.
• To enable updates you need to have a valid LiftTokens purchase code.
• If you're using the WordPress version of LiftTokens, keep in mind that you cannot update LiftTokens from the WordPress plugins page.

Manual updates

To manually update LiftTokens, download it again from LiftTokens and replace all the files of your installation with the new files from the downloaded LiftTokens package.

Having Problems?

If you're having any issues at all, please contact our friendly support team at support@lifttokens.com. Before contacting us, please make sure that your server has all the requirements listed above. On that same note, if you are using the WordPress version, please make sure that your WordPress installation has all the requirements listed above.

Payment not detected - Pending transaction

If you have sent a cryptocurrency payment and LiftTokens does not detect it (pending transaction), the most common reasons are as follows.

• The checkout page has been closed. The checkout page should not be closed before the payment is completed. If it's closed, the cron job function will still check payments but you should set it to run from your server, more details here.
• The amount sent is different from the one shown by LiftTokens. If the address is not dynamically generated, the amount sent must be the exact amount shown by LiftTokens or the payment will not be detected. Enable the generation of dynamic addresses to also accept amounts higher than the one shown by LiftTokens.
• The transaction is pending or has not been sent to the blockchain. Make sure the transaction is valid and has been sent. Use external websites like https://www.blockchain.com to check it.
• The service or wallet from which you sent the transaction is not working properly. Send the transaction from a personal wallet, not from an exchange. Transactions made from exchanges can create troubles and are not advised.
• Never use exchange addresses to receive payments, always use addresses from a personal wallet.
• Ensure that you are sending the funds to the main network and not to a testnet network. Alternatively, if you are in testnet mode, confirm that you are sending the funds to the correct testnet network.

WooCommerce order is not marked as completed

If you LiftTokens show the payment as completed, but the WooCommerce order is still pending. Check all of the following. To manually mark a WooCommerce order as completed, navigate to the LiftTokens > Transactions section. Find the specific transaction you wish to mark as completed and then select the Mark as completed option from the transaction menu.

• Disable all security plugins and try again.
• Make sure you are not blocking access to WordPress REST API.

Cross-domain configuration

If you want to show checkouts on domains other than the installation domain, including subdomains, your server must allow cross-origin requests. To enable cross-origin requests on your server, do the following:

Cross-domain configuration via server

• For Apache servers — Edit the .htaccess file of the domain where the plugin is installed and enter the code <IfModule mod_headers.c="">header('Access-Control-Allow-Origin: *');</IfModule> at the very top of the file. To make it works you need to have at least AllowOverride +FileInfo or AllowOverride All in the Apache config.
• For nginx servers — Edit the file /etc/nginx/nginx.conf of the domain where the plugin is installed and enter the code add_header Access-Control-Allow-Origin "*"; at the very top of the file. If you're using Plesk go to Domains > example.com > Apache and nginx settings > Additional nginx directives and insert
  add_header 'Access-Control-Allow-Origin' '*';.
• For OpenLiteSpeed servers — Visit https://openlitespeed.org/kb/setting-up-cors-on-openlitespeed/.

You can view tutorials for the most common server administration software in the list below:

• Plesk
• All Apache servers

Cross-domain configuration via PHP

If none of the previous solutions work or you can't change the server settings, follow the steps below:

• Edit the file lifttokens/config.php and enter the code define('LFT_CROSS_DOMAIN', true); at the end of the file.
• Upload the following folder into your destination domain(the domain where the checkout should be shown, not the one where LiftTokens is installed): lifttokens/media/fonts. You can upload the files where you want, for example, http://www.example.com/icons. If the checkouts are loaded on multiple domains upload the files on each domain.
• Edit again the file lifttokens/config.php and insert the code define('LFT_CROSS_DOMAIN_URL', 'YOUR-URL'); at the end of the file. Replace YOUR-URL with the URL that points to the files you just uploaded, for example, http://www.example.com/icons. If the checkouts are loaded on multiple domains replace YOUR-URL with the an array of URLs, for example, ["http://www.example.com/icons", "http://www.example-2.com/icons"].

Hide admin.php from URL

By default, the admin URL is something like https://your-website.com/lifttokens/admin.php. You can hide the admin.php part of the URL and make it like https://your-website.com/lifttokens/ by inserting the following code in your .htaccess file:

                                    <ifmodule mod_dir.c> DirectoryIndex admin.php</ifmodule>
                                

Reset username or password of the admin account

If you can no longer log in to the admin area, you can reset your password and username by following the steps below:

• Edit lifttokens/config.php.
• To change username, change the value of the constant LFT_USER.
• To change your password, change the value of the constant LFT_PASSWORD. The new password must be saved as a hash. To generate an hash for your password visit https://board.support/docs/files/password.php?p=123456. Change 123456 with your password.
• Warning Changing login details will make settings encrypted with the old password unrecoverable, including addresses generated via nodes and their private keys. If you don't know the old login data and the password hash, you won't be able to recover the data in the future. The password hash can be found in the config.php file of the LiftTokens folder.

If you're using the WordPress version, you can also delete the config.php file and LiftTokens will generate it again on reload.

Address generation

Single address

By default, LiftTokens use the single address set in Settings > Cryptocurrency addresses for all transactions in the same cryptocurrency. More details below.

• LiftTokens detect the payment from its cryptocurrency amount, in which case, the amount is always unique for each transaction.
• The amount always changes less than 0.02% of the original amount.
• The user must submit the exact amount shown by LiftTokens or the payment will not be detected.
• The underpayments setting is not compatible with the single address method. You have to activate the address generation to use this setting.
• An address can be used again 24 hours after the last outstanding transaction or immediately after completing the transaction or if a transaction has been canceled. Your can stop the reusing addresses after 24 hours by checking Settings > Stop reusing addresses.

Address generation

When using this feature LiftTokens generates a new and unique cryptocurrency address for each transaction.

• You can activate address generation via address list, nodes, Gemini, Coinbase, custom explorer.
• The transaction amount for the same FIAT amout remains the same.
• If the user sends an amount different from the one show by LiftTokens(partial payment) the transaction is still recognized but is completed only if the amount is equal or more than the requested amount. If the amount is less than the requested amount, and the underpayments setting is not active, the following happen:
  • The transaction status is set to Underpayment.
  • The amount sent and what remains to be sent are saved in the description of the transaction, view it from the Transactions area. Open the transaction menu to view the full description.
  • The user sees a message showing that there is an underpayment. You can customize the message from Settings > Payment form texts.
  • The webhook is not sent.
  • The TransactionCompleted JS event is not sent.
  • In case of WooCommerce, or with other integrations, the purchase is not completed.
• You can activate multiple address generation methods and use them as backup methods if one method fails. The priority is as follow:
  • 1. Nodes - Address generation via node has priority and if active is always used first.
  • 2. Custom explorer
  • 3. Address list
  • 4. Coinbase and Gemini - They are used only as last option.
  • 5. Single address
• The number of decimals is limited to 2 if the cryptocurrency of the transaction is a stablecoin.
• You must add the addresses in Settings > Cryptocurrency addresses also if you use address generation.

Address list

This method generates the address using a list of addresses manually set by you.

• You have to add at least 3 addresses to activate the address generation.
• Add the addresses in Settings > Cryptocurrency addresses, separate addresses by comma.
• The first address is reserved and used only if no more addresses are available, in this case the single address method is used.
• If you use the whitelist function, you need to add all the addresses in the whitelist.
• The LiftTokens balance section controls only the first address.

Underpayments

Activate the Settings > Accept transactions with underpayments option to start accepting underpayments. An underpayment occurs when the user sends an amount that is less than what LiftTokens requested.

• Only underpayments with a difference of 5% or less are accepted. If the user sends an amount that is less than 5% of the requested amount, the transaction will not be accepted.
• Underpayments only works if the address generation is active.

Webhooks are automated data sent from LiftTokens to a URL set by you when something happens. Use the webhook to validate and finalize the purchase. For security reasons you should always validate the purchase via webhook. You must be a developer and know how to coding to setup the webhook.

How to validate a purchase

• In Settings > Webhook > Webhook URL enter the destination URL. LiftTokens will send the data to this URL. The URL must point to a file that read the data received, with PHP, you can use the code below to read the data.

  $response = json_decode(file_get_contents('php://input'), true);

• In Settings > Webhook > Webhook secret key enter a secret password of your choice. The password will be included in all webhook calls (see key value in the example below). Use it to verify that the webhook is sent by LiftTokens and not someone else.
• Save the changes. LiftTokens will now start sending the below data when a payment is complete. To validate the transaction you must check that the value of the key status is equal to C. If the transaction was made from a dynamic checkout, you must also verify that the transaction amount_fiat value is correct and eqaual to the price amount of the purchased item.

  {
      "key": "123456789",
      "transaction": {
          "id": "231",

          "vat": {"amount":"0.33","percentage":"22","country":"Italy","country_code":"IT"}
      }
  }
  

Information

• The webhook sent when a payment is confirmed is only ever sent 1 time.

Dynamic checkouts

To create checkouts by HTML code place the code below into the web page where you want to show the checkout.

<div data-lft="custom-123" data-price=""></div>

URL

You can create a checkout page on the fly via the URL below. Replace [your-site] with your website URL. If you changed the directory name, replace lifttokens with the new directory name. For added security you can encrypt the parameter external_reference with the PHP API function lft_encryption(). Use the URL paremeter lang=LANGUAGE_CODE to change language. If you are using the Cloud, SaaS, or Reseller version, the URL of document.location must also include &cloud=API-KEY. Replace API-KEY with the value at LiftTokens > Account > API key.

https://[your-site]/lifttokens/pay.php?checkout_id=custom-123&price=0&external_reference=ABC

WordPress shortcode

If you are using the WordPress version you can also use the following shortcode.

[lifttokens id="custom-123" price="" description="" type="inline"]

Attributes

If you are using the WordPress shortcode or the URL method remove the prefix data- from all attributes.

data-lft

data-price

data-external-reference

data-redirect

data-currency

data-type

data-note

data-pay

Warning Security measure

When using dynamic checkouts without encrypting attributes you must validate the payment via webhook and verify that the transaction amount_fiat value is correct and eqaual to the price amount of the purchased item.

Languages

Add custom translations

You can add custom translations to translate the strings of Settings > Payment form texts.

• Include a file named translations.json into the LiftTokens root directory. Download example here.
• The content of the file is a JSON array like the one below. Replace LANGUAGE-CODE with the two-letters language code you would like to use. Get the language codes list here. Replace English string with the strings entered in Settings > Payment form texts, the strings must be in English and exactly the same. Replace Translation with the string translation.

                                         {
                                            "LANGUAGE-CODE": {
                                              "English string": "Translation",
                                              "English string": "Translation",
                                              ...
                                            },
                                            "LANGUAGE-CODE": {
                                              "English string": "Translation",
                                              "English string": "Translation",
                                              ...
                                            },
                                            ...
                                          }
                                      

Manually set the checkout language

You can force the checkout language via URL paramenter and JS variable. To set the language via URL parameter append the attribute ?lang=LANGUAGE-CODE to the client.js script link, e.g. <script id="lifttokens" src="[YOUR-URL]/js/client.js?lang=it"></script>. To set the language via JS variable insert the JS code <script>var LFT_LANGUAGE = "LANGUAGE-CODE";</script> into the checkout page, before the client.js script. Also, Settings > Languages > Payment form language must be set to Default.

Information

• Both admin-side and client-side are multilingual. You can set the languages from Settings > Languages.
• If the language is set to multilingual the language will be the browser language of the user.
• To check the checkout language you must be logged out. If you are logged in as an administrator, log out or open the payment page from another browser or use the browser's private / incognito window.
• If you are using the WordPress version and your website is multilingual, LiftTokens will use the active page language if Settings > Languages > Payment form language is set to Default. If you are using WooCommerce or Easy Digital Downloads, you need WPML or Polylang to redirect the user to the payment page in the correct language.

Custom tokens

You can add unlimited ERC-20 and BEP-20 tokens and start accepting payments with them.

Unlisted token

If your token is not listed on major cryptocurrency exchanges, LiftTokens cannot get your token's FIAT exchange rate. To solve this issue set the USD exchange rate of your token(set how much is the USD value of 1 token) in Settings > Custom token > USD exchange rate. To retrieve the exchange rate dynamically, input the URL in the Settings section under Custom token. The URL should directly provide the USD exchange rate when accessed using the HTTP GET method. For instance, refer to this example: https://lifttokens.com/docs/files/exchange_rate.txt.

Listed token

If your token is listed on major cryptocurrency exchanges, enter all the required information in Settings > Custom token and you are done.

Information

• The setting Token code must contain the code of your token, it must be lowercase and without spaces or symbols, e.g. btc, eth.

Nodes

Connect LiftTokens to a node to enable powerful features such as address generation or transfer in a completely decentralized way, without using any third-party services. The cloud version doesn't support the following features because we don't manage the wallet keys for you, please use the PHP or WP version if you want to use those features: transfer to address, instant conversion.

Setup

• In Node URL enter the URL of your node. The URL should contain the authentication details, e.g. http://user:pass@127.0.0.1:1832.
• In Node headers enter any additional headers required for authentication. Use the following syntax: key:value,key:value,....
• See the nodes as a service section for a list of ready-to-use node providers.

Address generation

This feature generate a new and unique cryptocurrency address for each transaction.

• Once the payment is received, it is transferred to the node transfer address, if set, otherwise to the corrispong address set in Settings > Cryptocurrency addresses. The amount will be less than the received amount because of the network fee spent for the transfer.
• Generated addresses are reused 24 hours after the last payment. We do this for performance reasons and to save you money when using Ethereum.
• For more details see the address generation section.
• Warning If the transfer fails, you can retrieve the private key of the wallet containing the funds using either the PHP API function lft_encryption() or the REST API function encryption. To decrypt, use the value stored in the database row btc-addresses or eth-addresses in the lft_settings table. Decryption will reveal the addresses and their corresponding private keys.
• Warning Changing your LiftTokens login details could result in loss of funds, if there are locked funds in the generated addresses. More details here.

Address generation via Xpub - Bitcoin only

Address generation via Xpub is another way to generate Bitcoin addresses. It's more secure and generates fewer fees, but it's more complex to use.

• To enable the address generation simply enter the xpub key.
• The default address generation method supports alzo zpub and ypub keys. Address generation via node only supports xpub keys. If you only get the zpub key, convert it to an xpub key with a tool like https://github.com/jlopp/xpub-converter (download it and open the file index.html).
• Node address generation uses your node and the Bitcoin REST API to generate the address. Use it if your wallet doesn't support the address generated via the default method.
• You can get the xpub key from your wallet settings. All major non-custodial wallets like Electrum and Exodus can show it. It is recommended to use Electrum. Get the key from Wallet > Information.
• It's more secure because LiftTokens doesn't need any private keys to generate the addresses and only your wallet can access the funds sent to the generated addresses.
• Generate fewer fees because there is no need to transfer the amount from the generated address to your main address.
• If the Settings > Bitcoin Node > Transfer to address option is active, address generation via xpub is automatically disabled. LiftTokens does this because it doesn't have access to funds.
• Warning Not all wallets support the address generated via xpub by LiftTokens. Test with a small amount and see if your wallet shows the amount. If it doesn't show, your money can be recovered with your private keys but we don't provide any help for that. The support does not cover it. The Electrum wallet is compatible with LiftTokens addresses generated via xpub.
• Warning Because as xpub works, your wallet may stop checking addresses after 20 consecutive addresses with no balance. When testing, make sure you don't generate more than 20 addresses without sending any money to any of them.

Transfer to address

This feature automatically transfers the amount of cryptocurrency sent by the user to the dynamically generated address to an address set by you.

• If node address generation is enabled, LiftTokens will automatically manage and use the private keys of the generated addresses to perform the transfer.
• If node address generation is not enabled, you need to enter the wallet private key in Settings > Wallets. The private key must be that of the wallet of the address set in Settings > Cryptocurrency addresses.
  Warning We strongly recommend using a wallet with low or no balance to avoid risking losing all your money! Don't use your main wallet. Use a new dedicated wallet, just for LiftTokens.
• LiftTokens will attempt to make the transfer even if the address balance is not sufficient to cover the network fee. In that case the amount sent will be balance - fee cost and the balance of the address after the transfer will be zero or near zero in the case of Ethereum.

Transfer to address - Ethereum only

• If the payment received is not in ETH but in another token such as USDT or USDC, LiftTokens will send a small amount of ETH to the newly generated address to cover the network fee of the transfer.
• Since it is currently not possible to accurately estimate the network fee, a small amount of funds will be locked in the newly generated addresses. LiftTokens minimizes the locked amount by reusing the generated addresses every 24 hours.
• Warning Token transfer is currently expensive and could significantly reduce your earnings if the amount transferred is small.

Instant conversion - Ethereum only

This feature automatically converts the user-submitted cryptocurrency amount into another cryptocurrency such as USDT or USDC each time a transaction is completed.

• To enable this feature you must enter the private key of your wallet in Settings > Wallets. The private key must be the one of the wallet of the address set in Settings > Cryptocurrency addresses.
  Warning We strongly advise using a wallet with low or zero balance to avoid risking losing all your money! Do not use your main wallet. Use a new, dedicated wallet, only for LiftTokens.
• This feature is powered by Uniswap.
• If this function is active, the transfer function is disabled.
• Only ETH and ETH ERC-20 tokens are supported.
• Warning Token conversion is currently very expensive and may significantly reduce your earnings.

Refunds

More details about the refunds feature here.

Nodes as a service

Running your own node can be challenging. There are a number of services that run optimized node infrastructures for you, so you can focus on developing your application or product instead. The list below contains node providers that we have already tested with LiftTokens.

Lightning Network

Connect LiftTokens to a Lightning Network node to start accepting Bitcoin payments on the Lightning Network.

Setup

• In Node URL enter the URL of your Lightning Network node.
• In Macaroon enter your admin Macaroon in hex format.
• In Node headers enter any additional headers required for authentication. Use the following syntax: key:value,key:value,....
• See the nodes as a service section for a list of ready-to-use node providers.

Information

• Only LND nodes are supported. Details here.
• If the invoice generation fails (for example because there is not enough remote balance), the LiftTokens checkout goes back to the cryptocurrency list, informs the user of a problem and asks to use another cryptocurrency.
• Enable Settings > Email notifications > Lightning Network error to get notified by email when invoice generation fails.
• You can use Boltz to get remote balance.

Nodes as a service

Running your own Lightning Network node can be challenging. There are a number of services that run optimized node infrastructures for you, so you can focus on developing your application or product instead. The list below contains node providers that we have already tested with LiftTokens.

Gemini

Use Gemini to enable powerful features like address generation or instant currency conversion.

Setup

• Enter Gemini > Settings > API or visit https://exchange.gemini.com/settings/api.
• Click Create API key and as Scope select Primary, under API key settings check Found management, Trading, Require session heartbeat.
• Copy API key and API Secret and paste them in LiftTokens > Settings > Gemini.
• In Gemini click Create API key.

Address generation

This feature generate a new and unique cryptocurrency address for each transaction. To use it, you just have to activate it, no configuration is needed. For more details see the address generation section.

Transfer to address

This feature automatically transfers the cryptocurrency amount sent by the user to the dynamically generated address to the addresses set in Settings > Cryptocurrency addresses every time a transaction is completed.

• To increase the security of this feature use the LiftTokens whitelist.
• This function is active only if the address generation function is active.
• The destination addresses are those saved in Settings > Cryptocurrency addresses, you need to add all these addresses to the Gemini whitelist, do it from Gemini > Settings > Approved addresses or got to https://exchange.gemini.com/settings/approvedAddresses.

Custom Blockchain explorer

You can use a custom Blockchain explorer to analyze the blockchains and generate a new payment address for each transaction. To do that, follow the steps below. If you want to generate a new address for each transaction you can use https://api.blockchain.com/v3/#getdepositaddress.

Instructions

• In Settings > Custom Blockchain explorer enter the URLs to get the balance of your addresses (Balance URL), single transaction details (Transaction URL), list of the latest transactions (Transactions URL) and to activate the option that generate a new payment address for each transaction (Address generator URL). The base URLs must be the same for all cryptocurrencies, you must use the keyword {N} to automatically change the network URL part, {N} will be automatically replaced by btc, eth, doge based on the active cryptocurrency. Use {N2} to use bitcoin, ethereum, dogecoin instead. Use the keyword {R} to automatically set the address or transaction ID of the active LiftTokens transaction. For example, the URL https://blockscout.com/{N}/mainnet/api?module=account&action=balance&address={R} will become something like https://blockscout.com/btc/mainnet/api?module=account&action=balance&address=3EBVDZUU6M2Pvu4rAqHwNESDgXBfJTAz7r for Bitcoin balance and https://blockscout.com/eth/mainnet/api?module=account&action=balance&address=0x298b78d398dd02031c40a4ee42622856249aef3c for Ethereum balance.
• In Balance path, Transaction paths, Transactions paths, Address generator path enter the JSON array paths of the values to get. Use the following syntax:

  key>subkey>..., key>subkey>..., ...

  For example the Balance path of the following JSON response is result.

  {
     "message": "OK",
     "result": "99639645964023592",
     "status": "1"
  }
  

• In Transactions paths enter the JSON array paths to get the following values: transactions list path, transaction time in unix format, transaction address, transaction amount, number of confirmations, transaction hash. The paths must respect this exact order. For example, the Transaction paths value of the following JSON response is result,timeStamp,from,value,confirmations,hash.

  {
      "message": "OK",
      "result": [{
          "blockHash": "0x06e8ae18e4e324d6efd438f95bfc532bab21680d852a6ac6e67021ce1227d8c5",

• Set the setting Settings > Custom Blockchain explorer > Unit type to Satoshi | Wei | Dogecoin if the transactions value/amount is in Satoshi, Wei, Dogecoin. In the examples above the values are in Wei.
• You can use blockscout.com to test this feature, here the details:
  Unit type Satoshi | Wei | Dogecoin
  Balance URL https://blockscout.com/{N}/mainnet/api?module=account&action=balance&address={R}
  Balance path result
  Transaction URL https://blockscout.com/{N}/mainnet/api?module=transaction&action=gettxinfo&txhash={R}
  Transaction paths result>timeStamp,result>from,result>value,result>confirmations,result>hash
  Transactions URL https://blockscout.com/{N}/mainnet/api?module=account&action=txlist&address={R}
  Transactions paths result,timeStamp,from,value,confirmations,hash

Requirements

• All requests are made through the HTTP GET method. The custom explorer must support queries via HTTP GET method.
• The custom explorer must return data in JSON format.

Information

• We do not provide support for setting up your custom explorer. To get assistance, you can hire us.
• If the custom explorer is down or a query fails the default explores are autoamtiacally used insted.
• If the generation of a new payment address fails the default address is used instead.
• If the custom explorer does not support a cryptocurrency you can still use it, the default explorers will be used for the unsupported cryptocurrencies.

Refunds

Issue a refund from the Transactions area by clicking Issue a refund from the transaction menu.

• Enable refunds from Settings > Coinbase > Refunds, Settings > Bitcoin node > Refunds, or Settings > Ethereum node > Refunds.
• Coinbase refunds are supported by almost all cryptocurrencies, Bitcoin Node refunds only support Bitcoin refunds, Ethereum node refunds support refunds for Ethereum and all Ethereum-based cryptocurrencies.
• A cryptocurrency refund is a new transaction sent to the sender address of the original transaction and with the same amount as the original transaction. For this reason, you must have a sufficient balance of the transaction's cryptocurrency to cover the transaction amount.
• For security reasons, the address to send the refund to and the refund amount are obtained directly from the blockchain and verified with the transaction in the LiftTokens database. If the amounts or addresses do not match, an error will be displayed and the refund will not be sent.
• You can only issue refunds for completed or underpaid transactions.
• Refunds via nodes have priority over Coinbase.

Testnets

Testnets allow you to test LiftTokens and the exchange add-on without using real money. See the information below to undersatnd how to use them. When using testnet nodes you have to disable the node Address generation option.

Bitcoin Testnet

Ethereum Sepolia

Email Notifications

Configure the email notifications from Settings > Email notifications.

Information

• You can update the logo on the emails at Settings > Logo > Logo URL - PNG. Additionally, make sure to enable Settings > Logo > Display on the admin area.
• The logo in user emails will have no link attached to it, whereas the logo in admin email notifications will redirect to the LiftTokens admin area.

Problems?

Emails may not be delivered several reasons; below are the most common ones:

URL rewrite

You can enable the URL rewrite from Settings > URL rewrite. The default URLs of LiftTokens are not user-friendly and they include parameters. You can rewrite the URLs via .htaccess file. The code below rewrites the URLs of the checkout and invoice pages. The checkout URL changes from pay.php?checkout_id=ID to /checkout/ID. The invoice URL changes from pay.php?invoice=ID to /invoice/ID. The direct payment URL changes from pay.php?id=ID to /id/ID.

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteRule ^checkout/(.*)$/?$ pay.php?checkout_id=$1 [L,QSA]
  RewriteRule ^invoice/(.*)$/?$ pay.php?invoice=$1 [L,QSA]
  RewriteRule ^id/(.*)$/?$ pay.php?id=$1 [L,QSA] 
</IfModule>
                                

The values to insert in Settings > URL rewrite are checkout/ and invoice/.

Information

• We do not offer support for URL rewrite as it is not related to our product. To get assistance, you can hire us.
• The values of Settings > URL rewrite must always end with /.
• If you are using the cloud version this setting is not available.

Custom fields

Include additional custom fields in the checkout form from Settings > Checkout custom fields.

Information

• You can view the custom field values under the notes section in the transaction details.
• In the webhook and JS event, the custom field values are part of the notes value.
• The select field type should have a value format of field_name:option1:option2:option3. Replace field_name with the actual name of the field and option1, option2, and option3 with the select options, add as many options as you want.

Information

• Pending transactions older than 48 hours are deleted automatically. You can change the interval from Settings > Exchange rates refresh interval. Once a pending transaction is deleted, the receiving address linked to it will be available again.
• To disable a cryptocrrency from the payment options remove the cryptocrrency address.
• Multiple checkouts can be present in the same web page but only one will be active at same time.
• LiftTokens query the blockchain via AJAX every 5 seconds to verify the payment of pending transactions.
• To test a completed transction multiple times without a real payment add the following attributes to the checkout URL: ?demo=true&amount=[123]&id=[ID]&webhook_key=[key]. Replace [123] with the exact transaction cryptocurrency amount, [ID] with the LiftTokens transaction ID, [key] with the LiftTokens webhook secret key, this attribute is optional. The blockchain transaction time must be higher than the LiftTokens transaction time. If you are using the WordPress version, you have to set the webhook secret key.
• Add the debug=true attribute to the payment URL or admin URL to enable debugging in the browser console and PHP log.

Agents

You can create agents account to allow other people to access the LiftTokens admin area with limited privileges. Agents are not allowed to perform the following actions:

• View and save the settings.
• Create, save, and delete checkouts.

To create an agent account, edit the file config.php available in the LiftTokens installation folder and add the following code before the ?php> tag: define('LFT_AGENTS', [['USERNAME', 'PASSWORD'], ['USERNAME', 'PASSWORD']]); Replace USERNAME with the username of the agents and PASSWORD with the password hash of the agents. To generate a hash for your password, visit https://phppasswordhash.com/ or use the tool you prefer.

IP ban

LiftTokens permits a maximum of 10 unsuccessful login attempts within an hour. If you exceeds this limit, you will be barred from accessing the admin area for a duration of 1 hour. This blocking mechanism is based on the user's IP address and serves to deter brute force attacks aimed at uncovering login credentials. If you encounter the "Too many login attempts. Please retry again in a few hours." error, you have two options: either wait for a few hours or make changes to the LiftTokens database by deleting the ip-ban row from the lft_settings table.

Two-factor authentication

To add an extra layer of security, activate Google Authenticator and enable two-factor authentication (2FA) for logging into the admin area. To do this, follow the instructions below:

• Activate Settings > Two-factor authentication.
• Click Pairing button and scan the QR code with the Google Authenticator app.
• Enter the code generated by the Google Authenticator app in the Code field and click Validation.

Monero

• The Monero balance currently is not shown in the LiftTokens dashboard. We will try to add the support soon.
• The Monero payments are detected only if the transaction is within the last 5 block. If the transaction is older than 5 blocks it will not be detected. For this reason, the user should wait for the transaction to be confirmed before closing the payment page.

Shopify

To start accepting cryptocurrency payments in your Shopify store, follow the steps below.

• Open your store settings area and click Apps and sales channels, then click Develop apps.
• Click Create an app, enter the app name you want, and create the app.
• Click Configure Admin API scopes and select the following: write_assigned_fulfillment_orders, read_assigned_fulfillment_orders, write_orders, read_orders.
• Open the API credentials tab and click Install app, after the installation copy the API access token and paste it into LiftTokens > Settings > Shopify > Access token.
• In LiftTokens > Settings > Shopify > Store URL enter you store URL, e.g. https://schiocco.myshopify.com.
• Open again your store settings area and click Checkout and accounts, insert the following code into the Order status page field:

  <script>
      if (!window.location.search.includes("cryptocurrency")) {
          let LIFTTOKENS_URL = "http://example.com/lifttokens";
          let LIFTTOKENS_PAYMENT_METHOD_TEXT = ["Pay with Crypto"];
          let LIFTTOKENS_INTERVAL = setInterval(function () {
              let element = document.getElementsByClassName("payment-method-list__item__info");
              if (element.length) {
                  if (LIFTTOKENS_PAYMENT_METHOD_TEXT.includes(element[0].innerHTML)) {
                      document.location = LIFTTOKENS_URL + "/pay.php?checkout_id=custom-shopify&price=" + Shopify.checkout.payment_due + "&currency=" + Shopify.checkout.currency + "&external-reference=shopify_" + Shopify.checkout.order_id + "&redirect=" + encodeURIComponent(document.location.href) + "&note=Shopify Order ID " + Shopify.checkout.order_id
                  }
                  clearInterval(LIFTTOKENS_INTERVAL);
              }
          }, 50);
      }
  </script>
  

  Replace http://example.com/lifttokens with your LiftTokens admin URL, without the /admin.php part. If you are using the Cloud, SaaS or Reseller, version, the URL of document.location must also include &cloud=API-KEY. Replace API-KEY with the value at LiftTokens > Account > API key.
• Open again your store settings area and click Payments, then click Add manual payment method and Create custom payment method. As Custom payment method name enter Pay with Crypto. You can change "Pay with Crypto" with something else but in such a case you have to replace it also on the code of the previous point. If you add translatons you have to add them in the code of the previous point, e.g. let LIFTTOKENS_PAYMENT_METHOD_TEXT = ["Pay with Crypto", "Pagar con Cripto", "ادفع باستخدام Crypto"];.
