Address generation

Single address

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

• InfraPay 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 InfraPay or the payment will not be detected.

Address generation

When using this feature InfraPay generates a new and unique cryptocurrency address for each transaction. More details below.

• 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 InfraPay(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 setting Settings > Accept transactions with underpayments 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.
• The number of decimals is limited to 2 if the cryptocurrency of the transaction is a stablecoin.

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.
• 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.
• The InfraPay balance section controls only the first address.

Webhooks are automated data sent from InfraPay 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. InfraPay 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 InfraPay and not someone else.
• Save the changes. InfraPay 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",
          "title": "My checkout title",
          "description": "My checkout description",

          "amount": "0.001",
          "amount_fiat": "0.1",
          "cryptocurrency": "eth",
          "currency": "eur",
          "external_reference": "",
          "creation_time": "2022-04-14 10:00:00",
          "status": "C",
          "webhook": "1"
          "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-infrapay="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 InfraPay with the new directory name. For added security you can encrypt the parameter external_reference with the PHP API function bxc_encryption(). Use the URL paremeter lang=LANGUAGE_CODE to change language.

https://dash.infrapay.co/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.

[infrapay 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-InfraPay

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.

• 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="boxcoin" src="dash.infrapay.co/js/client.js?lang=it"></script>. To set the language via JS variable insert the JS code <script>var BXC_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, InfraPay 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, InfraPay 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://www.infrapay.co/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 InfraPay to a node to enable powerful features such as address generation or transfer in a completely decentralized way, without using any third-party services.

Setup

• In Node URL enter the URL of your node. The URL should contain the authentication details, e.g. http://user:[email protected]: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 Changing your InfraPay 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 InfraPay 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. InfraPay does this because it doesn't have access to funds.
• Warning Not all wallets support the address generated via xpub by InfraPay. 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 InfraPay 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.

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 InfraPay.
• 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 will significantly reduce your earnings.

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://www.blockchain.com/api/api_receive.

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 InfraPay 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",

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

• Help setting up your custom explorer is not included in the support. You can hire us, we charge 60$ / hour. Min 30 min.
• 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 InfraPay 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 InfraPay 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 Goerli

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.
• InfraPay 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 InfraPay transaction ID, [key] with the InfraPay webhook secret key, this attribute is optional. The blockchain transaction time must be higher than the InfraPay 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.
