README

The CoinGate PHP library provides convenient access to the CoinGate API from applications written in the PHP language.

Requirements

PHP 7.3.0 and later.

Composer

You can install library via Composer. Run the following command:

composer require coingate/coingate-php

Manual Installation

If you do not wish to use Composer, you can download the latest release. Then, to use the library, include the init.php file.

require_once('/path/to/coingate-php/init.php');

Dependencies

The library require the following extensions in order to work properly:

• curl, although you can use your own non-cURL client if you prefer
• json

If you use Composer, these dependencies should be handled automatically. If you install manually, you'll want to make sure that these extensions are available.

Getting Started

You can sign up for a CoinGate account at https://coingate.com for production and https://sandbox.coingate.com for testing (sandbox).

Please note, that for Sandbox you must generate separate API credentials on https://sandbox.coingate.com. API credentials generated on https://coingate.com will not work for Sandbox mode.

Usage of CoinGate PHP library looks like:

$client = new \CoinGate\Client('YOUR_API_TOKEN');

In order, to use sandbox mode, you need to set second parameter to true.

$client = new \CoinGate\Client('YOUR_API_TOKEN', true);

If you plan to use Public API endpoints only, authentication is not required.

$client = new CoinGate\Client();

// if needed you can set configuration parameters later
$client->setApiKey('YOUR_API_TOKEN');
$client->setEnvironment('sandbox');

Full documentation of the CoinGate API can be found here

Example

An example of an app using this library can be found here

Payment Gateway API

Create Order

Create order at CoinGate and redirect shopper to invoice (payment_url).

$params = [
    'order_id'          => 'YOUR-CUSTOM-ORDER-ID-115',
    'price_amount'      => 1050.99,
    'price_currency'    => 'USD',
    'receive_currency'  => 'EUR',
    'callback_url'      => 'https://example.com/payments?token=6tCENGUYI62ojkuzDPX7Jg',
    'cancel_url'        => 'https://example.com/cart',
    'success_url'       => 'https://example.com/account/orders',
    'title'             => 'Order #112',
    'description'       => 'Apple Iphone 13'
];

try {
    $order = $client->order->create($params);
} catch (\CoinGate\Exception\ApiErrorException $e) {
    // something went wrong...
    // var_dump($e->getErrorDetails());
}

echo $order->id;

Checkout

Placing created order with pre-selected payment currency (BTC, LTC, ETH, etc). Display payment_address and pay_amount for shopper or redirect to payment_url. Can be used to white-label invoices.

$checkout = $client->order->checkout(7294, [
    'pay_currency' => 'BTC'
]);

Get Order

After creating an order, you will get an ORDER ID. This ID will be used for GET ORDER requests.

$order = $client->order->get(7294);

List Orders

Retrieving information of all placed orders.

$orders = $client->order->list([
    'created_at' => [
        'from' => '2022-01-25'
    ]
]);

Public API

Get Exchange Rate

Current exchange rate for any two currencies, fiat or crypto. This endpoint is public, authentication is not required.

$client->getExchangeRate('BTC', 'EUR');

List Exchange Rates

Current CoinGate exchange rates for Merchants and Traders. This endpoint is public, authentication is not required.

$client->listExchangeRates();

Ping

A health check endpoint for CoinGate API. This endpoint is public, authentication is not required.

$client->ping();

IP Addresses

Get IP addresses of CoinGate servers

$client->getIPAddresses();

Currencies

$client->getCurrencies();

// Crypto + Native + Merchant Pay 
$client->getCheckoutCurrencies();

// get Merchant Pay currencies only
$client->getMerchantPayCurrencies();

// get Merchant Receive currencies only
$client->getMerchantPayoutCurrencies();

Platforms

$client->getPlatforms();

Custom Request Timeout

To modify request timeouts (connect or total, in seconds) you'll need to tell the API client to use a CurlClient other than its default. You'll set the timeouts in that CurlClient.

// set up your tweaked Curl client
$curl = new \CoinGate\HttpClient\CurlClient();
$curl->setTimeout(10);
$curl->setConnectTimeout(5);

// tell CoinGate Library to use the tweaked Curl client
\CoinGate\Client::setHttpClient($curl);

// use the CoinGate API client as you normally would

Test API Connection

$result = \CoinGate\Client::testConnection('YOUR_API_TOKEN');

In order, to test API connection on sandbox mode, you need to set second parameter to true.

$result = \CoinGate\Client::testConnection('YOUR_API_TOKEN', true);

Attention plugin developers

Are you writing a plugin that integrates CoinGate and embeds our library? Then please use the setAppInfo function to identify your plugin. For example:

\CoinGate\Client::setAppInfo("MyAwesomePlugin", "1.0.0");

The method should be called once, before any request is sent to the API. The second parameter is optional.
