Coinbase Commerce

The official PHP library for the Coinbase Commerce API.

Table of contents

PHP versions

PHP version 5.4 and above are supported.

Documentation

For more details visit Coinbase API docs.

To start using this library register an account on Coinbase Commerce. You will find your API_KEY from User Settings.

Next initialize a Client for interacting with the API. The only required parameter to initialize a client is apiKey, however, you can also pass in baseUrl, apiVersion and timeout. Parameters can be also be set post-initialization:

use CoinbaseCommerce\ApiClient;

//Make sure you don't store your API Key in your source code!
$apiClientObj = ApiClient::init(<API_KEY>);
$apiClientObj->setTimeout(3);

The API resource class provides the following static methods: list, all, create, retrieve, updateById, deleteById. Additionally, the API resource class also provides the following instance methods: save, delete, insert, update.

Each API method returns an ApiResource which represents the JSON response from the API. When the response data is parsed into objects, the appropriate ApiResource subclass will automatically be used.

Client supports the handling of common API errors and warnings. All errors that occur during any interaction with the API will be raised as exceptions.

Error Status Code
APIException *
InvalidRequestException 400
ParamRequiredException 400
ValidationException 400
AuthenticationExceptionn 401
ResourceNotFoundException 404
RateLimitExceededException 429
InternalServerException 500
ServiceUnavailableException 503

Installation

Install with composer:

composer require coinbase/coinbase-commerce

Usage

use CoinbaseCommerce\ApiClient;

//Make sure you don't store your API Key in your source code!
ApiClient::init('API_KEY');

Checkouts

Checkouts API docs More examples on how to use checkouts can be found in the examples/Resources/CheckoutExample.php file

Load checkout resource class

use CoinbaseCommerce\Resources\Checkout;

Retrieve

$checkoutObj = Checkout::retrieve(<checkout_id>);

Create

$checkoutData = [
    'name' => 'The Sovereign Individual',
    'description' => 'Mastering the Transition to the Information Age',
    'pricing_type' => 'fixed_price',
    'local_price' => [
        'amount' => '100.00',
        'currency' => 'USD'
    ],
    'requested_info' => ['name', 'email']
];
$newCheckoutObj = Checkout::create($checkoutData);

// or

$newCheckoutObj = new Checkout();

$newCheckoutObj->name = 'The Sovereign Individual';
$newCheckoutObj->description = 'Mastering the Transition to the Information Age';
$newCheckoutObj->pricing_type = 'fixed_price';
$newCheckoutObj->local_price = [
    'amount' => '100.00',
    'currency' => 'USD'
];
checkoutObj->requested_info = ['name', 'email'];

checkoutObj->save();

Update

$checkoutObj = new Checkout();

$checkoutObj->id = <checkout_id>;
$checkoutObj->name = 'new name';

$checkoutObj->save();
// or
$newParams = [
    'name' => 'New name'
];

Checkout::updateById(<checkout_id>, $newParams});

Delete

$checkoutObj = new Checkout();

$checkoutObj->id = <checkout_id>;
$checkoutObj->delete();

// or

Checkout::deleteById(<checkout_id>);

List

List method returns ApiResourceList object.

$params = [
    'limit' => 2,
    'order' => 'desc'
];

$list = Checkout::getList($params);

foreach($list as $checkout) {
    var_dump($checkout);
}

// Get number of items in list
$count = $list->count();

// or
$count = count($list);

// Get number of all checkouts
$countAll = $list->countAll();

// Get pagination
$pagination = $list->getPagination();

// To load next page with previous setted params(in this case limit, order)
if ($list->hasNext()) {
    $list->loadNext();
    
    foreach($list as $checkout) {
        var_dump($checkout);
    }
}

Get all checkouts

$params = [
    'order' => 'desc'  
];

$allCheckouts = Checkout::getAll($params);

Charges

Charges API docs More examples on how to use charges can be found in the examples/Resources/ChargeExample.php file

Load charge resource class

use CoinbaseCommerce\Resources\Charge;

Retrieve

$chargeObj = Charge::retrieve(<charge_id>);

Create

$chargeData = [
    'name' => 'The Sovereign Individual',
    'description' => 'Mastering the Transition to the Information Age',
    'local_price' => [
        'amount' => '100.00',
        'currency' => 'USD'
    ],
    'pricing_type' => 'fixed_price'
];
Charge::create($chargeData);

// or
$chargeObj = new Charge();

$chargeObj->name = 'The Sovereign Individual';
$chargeObj->description = 'Mastering the Transition to the Information Age';
$chargeObj->local_price = [
    'amount' => '100.00',
    'currency' => 'USD'
];
$chargeObj->pricing_type = 'fixed_price';
$chargeObj->save();

List

$list = Charge::getList();

foreach($list as $charge) {
    var_dump($list);
}

$pagination = $list->getPagination();

Get all changes

$allCharges = Charge::getAll();

Events

Events API Docs More examples on how to use events can be found in the examples/Resources/EventExample.php file

Load event resource class

use CoinbaseCommerce\Resources\Event;

Retrieve

$eventObj = Event::retrieve(<event_id>);

List

$listEvent = Event::getList();

foreach($listEvent as $event) {
    var_dump($event);
}

$pagination = $listEvent->getPagination();

Get all events

$allEvents = Event::getAll();

Warnings

It's prudent to be conscious of warnings. The library will log all warnings to a standard PSR-3 logger if one is configured.

use CoinbaseCommerce\ApiClient;

//Make sure you don't store your API Key in your source code!
$apiClientObj = ApiClient::init(<API_KEY>);
$apiClientObj->setLogger($logger);

Webhooks

Coinbase Commerce signs the webhook events it sends to your endpoint, allowing you to validate and verify that they weren't sent by someone else. You can find a simple example of how to use this with Express in the examples/Webhook folder

Verify Signature header

use CoinbaseCommerce\Webhook;

try {
    Webhook::verifySignature($signature, $body, $sharedSecret);
    echo 'Successfully verified';
} catch (\Exception $exception) {
    echo $exception->getMessage();
    echo 'Failed';
}
