README
The code's copyright belongs to shakurov and alexstewartja, but because he hasn't merged the damn pull request for too long, I had to fork a copy and change the namespace for the convenience of composer request.
Installation
You can install the package via composer:
composer require forecho/coinbase
The service provider will automatically register itself.
You must publish the config file with:
php artisan vendor:publish --provider="Forecho\Coinbase\CoinbaseServiceProvider" --tag="config"
This is the contents of the config file that will be published at config/coinbase.php
:
return [ 'apiKey' => env('COINBASE_API_KEY'), 'apiVersion' => env('COINBASE_API_VERSION'), 'webhookSecret' => env('COINBASE_WEBHOOK_SECRET'), 'webhookJobs' => [ // 'charge:created' => \App\Jobs\CoinbaseWebhooks\HandleCreatedCharge::class, // 'charge:confirmed' => \App\Jobs\CoinbaseWebhooks\HandleConfirmedCharge::class, // 'charge:failed' => \App\Jobs\CoinbaseWebhooks\HandleFailedCharge::class, // 'charge:delayed' => \App\Jobs\CoinbaseWebhooks\HandleDelayedCharge::class, // 'charge:pending' => \App\Jobs\CoinbaseWebhooks\HandlePendingCharge::class, // 'charge:resolved' => \App\Jobs\CoinbaseWebhooks\HandleResolvedCharge::class, ], 'webhookModel' => Forecho\Coinbase\Models\CoinbaseWebhookCall::class, ];
In the webhookSecret
key of the config file you should add a valid webhook secret. You can find the secret used at the webhook configuration settings on the Coinbase Commerce dashboard.
Next, you must publish the migration with:
php artisan vendor:publish --provider="Forecho\Coinbase\CoinbaseServiceProvider" --tag="migrations"
After the migration has been published you can create the coinbase_webhook_calls
table by running the migrations:
php artisan migrate
Finally, take care of the routing: At the Coinbase Commerce dashboard you must add a webhook endpoint, for example: https://example.com/api/coinbase/webhook
Usage
Charges
List charges:
$charges = Coinbase::getCharges();
Create a charge:
$charge = Coinbase::createCharge([ 'name' => 'Name', 'description' => 'Description', 'local_price' => [ 'amount' => 100, 'currency' => 'USD', ], 'pricing_type' => 'fixed_price', ]);
Show a charge:
$charge = Coinbase::getCharge($chargeId);
Cancel a charge:
$charge = Coinbase::cancelCharge($chargeId);
Resolve a charge:
$charge = Coinbase::resolveCharge($chargeId);
Checkouts
List checkouts:
$checkouts = Coinbase::getCheckouts();
Create a checkout:
$checkout = Coinbase::createCheckout([ 'name' => 'Name', 'description' => 'Description', 'local_price' => [ 'amount' => 100, 'currency' => 'USD', ], 'pricing_type' => 'fixed_price', ]);
Show a checkout:
$checkout = Coinbase::getCheckout($checkoutId);
Update a checkout:
$checkout = Coinbase::updateCheckout($checkoutId, [ 'name' => 'New Name', 'description' => 'New Description', 'local_price' => [ 'amount' => 200, 'currency' => 'USD', ], 'requested_info' => [ 'name', ], ]);
Delete a checkout:
$checkout = Coinbase::deleteCheckout($checkoutId);
Invoices
List invoices:
$invoices = Coinbase::getInvoices();
Create an invoice:
$invoice = Coinbase::createInvoice([ 'business_name' => 'Business Name', 'customer_email' => 'customer@example.com', 'customer_name' => 'Customer Name', 'local_price' => [ 'amount' => 100, 'currency' => 'USD', ], 'memo' => 'A memo/description for the invoice', ]);
Show an invoice:
$invoice = Coinbase::getInvoice($invoiceId);
Void an invoice:
$invoice = Coinbase::voidInvoice($invoiceId);
Resolve an invoice:
$invoice = Coinbase::resolveInvoice($invoiceId);
Events
List events:
$events = Coinbase::getEvents();
Show an event:
$event = Coinbase::getEvent($eventId);
Webhooks
Coinbase Commerce will send out webhooks for several event types. You can find the full list of events types in the Coinbase Commerce documentation.
Coinbase Commerce will sign all requests hitting the webhook url of your app. This package will automatically verify if the signature is valid. If it is not, the request was probably not sent by Coinbase Commerce.
Unless something goes terribly wrong, this package will always respond with a 200
to webhook requests. Sending a 200
will prevent Coinbase Commerce from resending the same event over and over again. All webhook requests with a valid signature will be logged in the coinbase_webhook_calls
table. The table has a payload
column where the entire payload of the incoming webhook is saved.
If the signature is not valid, the request will not be logged in the coinbase_webhook_calls
table but a Forecho\Coinbase\Exceptions\WebhookFailed
exception will be thrown.
If something goes wrong during the webhook request the thrown exception will be saved in the exception
column. In that case the controller will send a 500
instead of 200
.
There are two ways this package enables you to handle webhook requests: you can opt to queue a job or listen to the events the package will fire.
Handling webhook requests using jobs
If you want to do something when a specific event type comes in you can define a job that does the work. Here's an example of such a job:
<?php namespace App\Jobs\CoinbaseWebhooks; use Illuminate\Bus\Queueable; use Illuminate\Queue\SerializesModels; use Illuminate\Queue\InteractsWithQueue; use Illuminate\Contracts\Queue\ShouldQueue; use Forecho\Coinbase\Models\CoinbaseWebhookCall; class HandleCreatedCharge implements ShouldQueue { use InteractsWithQueue, Queueable, SerializesModels; /** @var \Forecho\Coinbase\Models\CoinbaseWebhookCall */ public $webhookCall; public function __construct(CoinbaseWebhookCall $webhookCall) { $this->webhookCall = $webhookCall; } public function handle() { // do your work here // you can access the payload of the webhook call with `$this->webhookCall->payload` } }
We highly recommend that you make this job queueable, because this will minimize the response time of the webhook requests. This allows you to handle more Coinbase Commerce webhook requests and avoid timeouts.
After having created your job you must register it at the jobs
array in the coinbase.php
config file. The key should be the name of the coinbase commerce event type where but with the .
replaced by _
. The value should be the fully qualified classname.
// config/coinbase.php 'jobs' => [ 'charge:created' => \App\Jobs\CoinbaseWebhooks\HandleCreatedCharge::class, ],
Handling webhook requests using events
Instead of queueing jobs to perform some work when a webhook request comes in, you can opt to listen to the events this package will fire. Whenever a valid request hits your app, the package will fire a coinbase::<name-of-the-event>
event.
The payload of the events will be the instance of CoinbaseWebhookCall
that was created for the incoming request.
Let's take a look at how you can listen for such an event. In the EventServiceProvider
you can register listeners.
/** * The event listener mappings for the application. * * @var array */ protected $listen = [ 'coinbase::charge:created' => [ App\Listeners\ChargeCreatedListener::class, ], ];
Here's an example of such a listener:
<?php namespace App\Listeners; use Illuminate\Contracts\Queue\ShouldQueue; use Forecho\Coinbase\Models\CoinbaseWebhookCall; class ChargeCreatedListener implements ShouldQueue { public function handle(CoinbaseWebhookCall $webhookCall) { // do your work here // you can access the payload of the webhook call with `$webhookCall->payload` } }
We highly recommend that you make the event listener queueable, as this will minimize the response time of the webhook requests. This allows you to handle more Coinbase Commerce webhook requests and avoid timeouts.
The above example is only one way to handle events in Laravel. To learn the other options, read the Laravel documentation on handling events.
Advanced usage
Retry handling a webhook
All incoming webhook requests are written to the database. This is incredibly valuable when something goes wrong while handling a webhook call. You can easily retry processing the webhook call, after you've investigated and fixed the cause of failure, like this:
use Forecho\Coinbase\Models\CoinbaseWebhookCall; CoinbaseWebhookCall::find($id)->process();
Performing custom logic
You can add some custom logic that should be executed before and/or after the scheduling of the queued job by using your own model. You can do this by specifying your own model in the model
key of the coinbase
config file. The class should extend Forecho\Coinbase\Models\CoinbaseWebhookCall
.
Here's an example:
use Forecho\Coinbase\Models\CoinbaseWebhookCall; class MyCustomWebhookCall extends CoinbaseWebhookCall { public function process() { // do some custom stuff beforehand parent::process(); // do some custom stuff afterwards } }
