Laravel Multi Payment GatewayAppearance
Paystack Webhook
By following the instructions below, you can effectively manage paystack webhook events.
Config Setup
Ensure that this setup is present inside the multipayment-gateways.php configuration file
php
[
/*
* This refers to the name of the payment gateway being used.
*/
'name' => 'paystack',
/**
* When set to false, the package will not verify the signature of the webhook call.
*/
'verify_signature' => true,
/*
* This secret key is used to validate the signature of the webhook call.
*/
'signing_secret' => env('PAYSTACK_SECRET'),
/*
* This refers to the header that holds the signature.
*/
'signature_header_name' => 'HTTP_X_PAYSTACK_SIGNATURE',
/*
* This class is responsible for verifying the validity of the signature header.
*
* It should implement the interface \MusahMusah\LaravelMultipaymentGateways\SignatureValidator\PaymentWebhookSignatureValidator.
*/
'signature_validator' => \MusahMusah\LaravelMultipaymentGateways\SignatureValidator\DefaultSignatureValidator::class,
/**
* The webhook handler option allows you to choose how webhook requests are handled in your application.
*
* Available options:
* - 'job': Webhook requests will be handled by a job.
* - 'event': Webhook requests will be handled by an event.
*
* Default: 'job'
*/
'payment_webhook_handler' => 'job',
/**
* The payment_webhook_job option allows you to specify the job class that will be used to process webhook requests for payment methods.
*
* This should be set to a class that extends \MusahMusah\LaravelMultipaymentGateways\Jobs\ProcessPaymentWebhookJob.
*/
'payment_webhook_job' => '',
/**
* The payment_webhook_event option allows you to specify the event class that will be used to process webhook requests for payment methods.
*
* This should be set to a class that extends \MusahMusah\LaravelMultipaymentGateways\Events\PaymentWebhookReceivedEvent.
*/
'payment_webhook_event' => '',
]
Paystack Signature Validator
The package ships with a default signature validator for paystack which is used as shown below:
php
'signature_validator' => \MusahMusah\LaravelMultipaymentGateways\SignatureValidator\DefaultSignatureValidator::class,
Custom Signature Validator
To use a custom class for signature validation, create a class that implements the MusahMusah\LaravelMultipaymentGateways\SignatureValidator\PaymentWebhookSignatureValidator interface. Then ensure to update the paystack webhook config to use your custom class as illustrated below.
php
'signature_validator' => YourCustomSignatureValidator::class,
Disabling Signature Validation
In case you opt not to validate the webhook events, you can disable the signature validation by setting the verify_signature option to false as shown below:
php
'verify_signature' => false,
The package will then not verify the signature of the webhook call.
Webhook Handler
This refers to the approach you wish to adopt for processing the webhook event, either by dispatching a job or an event. By default, we have set the configuration to use a job.
If you prefer to use an event, you can update it following the example provided below.
php
'payment_webhook_handler' => 'event',
Handle Webhook Using Job
To manage paystack webhook events using job, create a job class that extends the MusahMusah\LaravelMultipaymentGateways\Jobs\ProcessPaymentWebhookJob class, and modify the configuration as illustrated below:
php
'payment_webhook_job' => YourCustomPaystackWebhookJob::class,
Sample Usage:
php
use MusahMusah\LaravelMultipaymentGateways\Jobs\ProcessPaymentWebhookJob;
class YourCustomPaystackWebhookJob extends ProcessPaymentWebhookJob implements ShouldQueue
{
public function handle()
{
// Get the webhook data
$webhookData = $this->webhookPayload;
// Handle the webhook
}
}
Handle Webhook Using Event
To manage paystack webhook events using event, you need to create a listener class that listens to the MusahMusah\LaravelMultipaymentGateways\Events\PaymentWebhookReceived event triggered by the package. Then, you should adjust the configuration settings as shown below:
php
'payment_webhook_event' => '\MusahMusah\LaravelMultipaymentGateways\Events\PaymentWebhookReceivedEvent',
Register the event listener in the EventServiceProvider class.
php
use MusahMusah\LaravelMultipaymentGateways\Events\PaymentWebhookReceivedEvent;
use App\Listeners\YourCustomPaystackWebhookListener;
protected $listen = [
PaymentWebhookReceivedEvent::class => [
YourCustomPaystackWebhookListener::class,
],
];
Sample Usage:
php
use MusahMusah\LaravelMultipaymentGateways\Events\PaymentWebhookReceivedEvent;
class YourCustomPaystackWebhookListener
{
public function handle(PaymentWebhookReceivedEvent $event)
{
// Get the webhook data
$webhookData = $event->webhookPayload;
// Handle the webhook
}
}
Route Setup
To include the paystack webhook route, follow the example below and add the route to your api.php file:
php
use Illuminate\Support\Facades\Route;
Route::webhooks('/paystack/webhook', 'paystack');
