Usage

Accounts

$accountId = '31804390-d44e-49e9-8698-ca781e0eb806';

$result = $cryptopay->accounts->allTransactions($accountId);

Channels

A channel is a static cryptocurrency address that may be assigned to each one of your customers.

Channels API docs

List channels

$result = $cryptopay->channels->all();

Create a channel

$params = [
  'name' => 'Channel name',
  'pay_currency' => 'BTC',
  'receiver_currency' => 'EUR'
];

$result = $cryptopay->channels->create($params);

$result = $cryptopay->channels->allPayments($channelId);

CoinWithdrawals

In addition to accepting payments through the Cryptopay payment gateway, it is also possible to make payments to your customers in any of the cryptocurrency currently supported by Cryptopay. In Cryptopay, these payments are called “Coin Withdrawal”. The process of requesting coin withdrawal is almost the same for a customer in Cashier as the process of making a deposit with one exception - the customer will need to specify the address of the wallet he wants to send the cryptocurrency to.

Callbacks

Documentation

All callbacks needs to be validated with signature

<?php

// Get CallbackJson
$callbackJson = file_get_contents('php://input');

// Get headers
$headers = getallheaders();

$cryptopay->validateCallback($callbackJson, $headers);

If the signature is wrong, the package validation will throw ForbiddenException. Otherwise, it will return object.
