README

Use syehan/webhook-plugin. A webhook is a way for an app to provide information to another app about a particular event. The way the two apps communicate is with a simple HTTP request.

Installation

1 - You can install the package via composer:

$ composer require syehan/webhook-plugin

2 - Now publish the migration for webhook tables:

php artisan october:migrate

Note: It will generate migration table syehan_webhook_webhooks.

Required Dependency

This plugin required dependency by Spatie Webhook Server (https://github.com/spatie/laravel-webhook-server) If there's some trouble, here's another way to do :

You can install it by :

composer require spatie/laravel-webhook-server "^3.4"

Or, Install composer merge plugin like this :

composer require wikimedia/composer-merge-plugin "^2.0"

Next, adding allow plugins configuration in your composer.json :

"config": {
    "preferred-install": "dist",
    "allow-plugins": {
        "composer/installers": true,
        "wikimedia/composer-merge-plugin": true
    }
},

Then, adding extra configuration in your composer.json :

"extra": {
    "merge-plugin": {
        "include": [
            "plugins/*/*/composer.json"
        ],
        "recurse": true,
        "replace": false,
        "merge-dev": false
    }
},

Last but not least,

composer update

Config Webhook

If your have any setup for webhook server please make sure to copy our config below and paste in config/webhook-server.php.

     */
    'proxy' => null,

    /*

     */
    'events' => [
        'user_created' => 'user_created',
        'user_updated' => 'user_updated',
        'user_deleted' => 'user_deleted',
    ],

        'application/json' => 'application/json',
    ]
];

Registering your model

In Default we already registered the RainLab.User Model to this plugin. And there's two way to implement the webhook :

1 - By observing your model :

public function boot()
{
    /*
    |--------------------------------------------------------------------------
    | The Example how to implement webhook to your model
    |--------------------------------------------------------------------------
    |
    | This example able to make your model lifecycle such as, created, updated, deleted, etc. 
    | It's only available for past event.
    | For More about Observer lifecycle: check this -> https://laravel.com/docs/9.x/eloquent#observers
    | The Example to observe your model at below.
    */

    \RainLab\User\Models\User::observe(\Syehan\Webhook\Observers\WebhookObserver::class);
}

2 - Or, more creative way is :

public function boot()
{
    /*
    |--------------------------------------------------------------------------
    | Implement as Behavior
    |--------------------------------------------------------------------------
    |
    | Maybe you want make another unique events for your model. Just pass this behavior into your model.
    | You will able to call $this->webhook() to anything you like as long as your model called.
    | The Example below.
    */

    \RainLab\User\Models\User::extend(function($model) {
        $model->implement[] = 'Syehan.Webhook.Behaviors.WebhookBehavior';         
    });
}

The second way of implementation is more flexible, we created function inside the behavior class like this :

public function webhook($model, $event_name, $payload = [])
{
    $webhook = WebhookManager::instance();
    $webhook->setModel($model)->setEvent($event)->setPayload($payload)->call();
}

It means, you able to call your webhook in your own way, for example :

public function beforeSave()
{
    $this->webhook($this, 'email_changed');
}

public function notifyUserSickToSlack()
{
    $payload = [
        'description' => 'User is sick',
        'name' => $model->name,
        'submitted_at' => now()->format('j F Y H:i:s'),
    ];
    
    $model->webhook($model, 'notify_to_slack', $payload);
}

after that, you must registering your event in config/webhook-server.php like this :

/*
 * At least you must have one event in this array. When you creating the events, make sure the format of the event is {LowerCaseModelName}_{EventName}
 * For example, I want to make event for user that has been created, simply you register it like user_created.
 * Another example is below.
 */
'events' => [
    'user_updated' => 'user_updated',
    'user_email_changed' => 'user_email_changed',
    'user_notify_to_slack' => 'user_notify_to_slack',
],

Lastly, create your webhook in the menu settings, create some request payload to other app domain and activate it.

Testing The Webhook

We recommend you to test using request baskets (https://rbaskets.in/web) to make sure the webhook is running well.
