# CoinGate PHP library for API v2
|
|
|
|
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](http://getcomposer.org/). Run the following command:
|
|
|
|
```bash
|
|
composer require coingate/coingate-php
|
|
```
|
|
|
|
## Manual Installation
|
|
|
|
If you do not wish to use Composer, you can download the [latest release](https://github.com/coingate/coingate-php/releases). Then, to use the library, include the `init.php` file.
|
|
|
|
```php
|
|
require_once('/path/to/coingate-php/init.php');
|
|
```
|
|
|
|
## Dependencies
|
|
|
|
The library require the following extensions in order to work properly:
|
|
|
|
- [`curl`](https://secure.php.net/manual/en/book.curl.php), although you can use your own non-cURL client if you prefer
|
|
- [`json`](https://secure.php.net/manual/en/book.json.php)
|
|
|
|
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:
|
|
|
|
```php
|
|
$client = new \CoinGate\Client('YOUR_API_TOKEN');
|
|
```
|
|
|
|
In order, to use sandbox mode, you need to set second parameter to `true`.
|
|
|
|
```php
|
|
$client = new \CoinGate\Client('YOUR_API_TOKEN', true);
|
|
```
|
|
|
|
If you plan to use Public API endpoints only, authentication is not required.
|
|
|
|
```php
|
|
$client = new CoinGate\Client();
|
|
|
|
// if needed you can set configuration parameters later
|
|
$client->setApiKey('YOUR_API_TOKEN');
|
|
$client->setEnvironment('sandbox');
|
|
```
|
|
|
|
## Payment Gateway API
|
|
|
|
### Create Order
|
|
|
|
Create order at CoinGate and redirect shopper to invoice (payment_url).
|
|
|
|
```php
|
|
$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...
|
|
}
|
|
|
|
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.
|
|
|
|
```php
|
|
$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.
|
|
|
|
```php
|
|
$order = $client->order->get(7294);
|
|
```
|
|
|
|
### List Orders
|
|
|
|
Retrieving information of all placed orders.
|
|
|
|
```php
|
|
$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.
|
|
|
|
```php
|
|
$client->getExchangeRate('BTC', 'EUR');
|
|
```
|
|
|
|
### List Exchange Rates
|
|
|
|
Current CoinGate exchange rates for Merchants and Traders. This endpoint is public, authentication is not required.
|
|
|
|

|
|
```
|
|
|
|
### Ping
|
|
|
|
A health check endpoint for CoinGate API. This endpoint is public, authentication is not required.
|
|
|
|
```php
|
|
$client->ping();
|
|
```
|
|
|
|
### IP Addresses
|
|
|
|
Get IP addresses of CoinGate servers
|
|
|
|
```php
|
|
$client->getIPAddresses();
|
|
```
|
|
|
|
### Currencies
|
|
|
|
```php
|
|
$client->getCurrencies();
|
|
|
|
// Crypto + Native + Merchant Pay
|
|
$client->getCheckoutCurrencies();
|
|
|
|
// get Merchant Pay currencies only
|
|
$client->getMerchantPayCurrencies();
|
|
|
|
// get Merchant Receive currencies only
|
|
$client->getMerchantPayoutCurrencies();
|
|
```
|
|
|
|
### Platforms
|
|
|
|
```php
|
|
$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.
|
|
|
|
```php
|
|
// 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
|
|
|
|
```php
|
|
$result = \CoinGate\Client::testConnection('YOUR_API_TOKEN');
|
|
```
|
|
|
|
In order, to test API connection on sandbox mode, you need to set second parameter to `true`.
|
|
|
|
```php
|
|
$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:
|
|
|
|
```php
|
|
\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. |
