README

Flutterwave can notify your application about various events via webhooks. This package can help you handle those webhooks. It will automatically verify all incoming requests and ensure they are coming from Flutterwave.

Please note that this package will NOT handle what should be done after the request has been validated. You should still write the code for that.

Installation

You can install the package via composer:

composer require adejorosam/laravel-flutterwave-webhook

The service provider will automatically register itself.

You must publish the config file with:

php artisan vendor:publish --provider="Adejorosam\LaravelFlutterwaveWebhook\LaravelFlutterwaveWebhookServiceProvider" --tag="config"

This is the contents of the config file that will be published at config/flutterwave-webhooks.php:

return [

    /*
     * Flutterwave will sign each webhook using the secret hash you fielded. 
     * You can do that at the webhook configuration settings: https://dashboard.flutterwave.com/account/webhooks.
     */
    'signing_secret' => env('SECRET_HASH'),


    /*
     * The classname of the model to be used. The class should equal or extend
     * \Spatie\WebhookClient\ProcessWebhookJob.
    */
    'process_webhook_job' => '',
];

In the signing_secret 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 flutterwave dashboard.

Next, you must publish the migration with:

php artisan vendor:publish --provider="Adejorosam\LaravelFlutterwaveWebhook\LaravelFlutterwaveServiceProvider" --tag="migrations"

After the migration has been published you can create the webhook_calls table by running the migrations:

php artisan migrate

Finally, take care of the routing: At the flutterwave dashboard you must configure at what url Flutterwave webhooks should hit your app. In the routes file of your app you must pass that route to Route::flutterwaveWebhooks:

Route::flutterwaveWebhooks('webhook-route-configured-at-the-flutterwave-dashboard');

Behind the scenes this will register a POST route to a controller provided by this package. Because Flutterwave has no way of getting a csrf-token, you must add that route to the except array of the VerifyCsrfToken middleware:

protected $except = [
    'webhook-route-configured-at-the-flutterwave-dashboard',
];

Usage

Flutterwave will send out webhooks for several event types. You can find the [full list of events types] in the Flutterwave documentation.

Flutterwave 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 Flutterwave.

Unless something goes terribly wrong, this package will always respond with a 200 to webhook requests. Sending a 200 will prevent Flutterwave from resending the same event over and over again. All webhook requests with a valid signature will be logged in the 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 webhook_calls table but a Adejorosam\LaravelWebhooks\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.

Storing and processing webhooks

After the signature is validated and the webhook profile has determined that the request should be processed, the package will store and process the request.

The request will first be stored in the webhook_calls table. This is done using the WebhookCall model.

Next, the newly created WebhookCall model will be passed to a queued job that will process the request. Any class that extends \Spatie\WebhookClient\ProcessWebhookJob is a valid job. Here's an example:

<?php
namespace Adejorosam\LaravelFlutterwaveWebhook;

use \Spatie\WebhookClient\ProcessWebhookJob;

//The class extends "ProcessWebhookJob" class as that is the class
//that will handle the job of processing our webhook before we have
//access to it.


class ProcessFlutterwaveWebhook extends ProcessWebhookJob
{
    public function handle()
    {
        $data = json_decode($this->webhookCall, true);
        //Do something with great with this!
       http_response_code(200); //Acknowledge you received the response
    }
}

You should specify the class name of your job in the process_webhook_job of the webhook-client config file.
