silverstripe-paypalwebhook

This module is a PayPal webhook event handling delegation interface, a subclass can handle one or more event and an event can be handled by one or more subclass

Requirements

• silverstripe/framework: ^4

Configuration

By default the environment is set to sandbox

Vulcan\PayPalWebhook\PayPalWebhook:
  environment: sandbox
  oauth_sandbox_clientid: ".."
  oauth_sandbox_secretid: ".."
  oauth_live_clientid: ".."
  oauth_live_secretid: ".."
  webhook_sandbox_id: ".."
  webhook_live_id: ".."

You can also use test keys and the webhook simulator will work fine with this module

WARNING: While this module is in sandbox mode, events will NOT be verified!

Usage

1. Install and dev/build
2. Add a sandbox webhook endpoint to PayPal that points to https://yourdomain.com/paypal-webhook and ensure that it sends the events you require
3. Create your functionality for your event(s):

<?php

use Vulcan\PayPalWebhook\Handlers\PayPalEventHandler;

class CustomerDisputeHandler extends PayPalEventHandler
{
    private static $events = [
        'CUSTOMER.DISPUTE.CREATED'
    ];

    public static function handle($event, array $data)
    {
        // $event is the string identifier of the event
        return "Do something here";
    }
}

Any subclass of PayPalEventHandler is detected and requires both the private static $events and public static function handle($event, $data) to be defined.

private static $events must be defined and can be a string containing a single event identifier or an array with multiple

public static function handle($event,$data) must be defined and should not call the parent. $data will be a \Stripe\Event object which has the exact same hierarchy as the JSON response depicted in their examples.

Features

• All handled events are logged, along with the responses from their handlers.
• Duplicates are ignored, if PayPal sends the same event more than once it won't be processed, but the logged event will count the occurence
• All events are verified to have been sent from PayPal using the webhook ID you defined in the configuration above

Why?

Easily introduce new event handling functionality without needing to touch any files relating to other event handling classes.
