Stripe Webhook PHP Example

stripe_webhook.php

<?php
// You can save this file as index.php and make it available in a public webhook directory in your app:
// http://example.com/webhooks/stripe/index.php

// In your Stripe Dashboard -> Webhooks page, add a LIVE and/or TEST URL:
// http://example.com/webhooks/stripe/

// Load the Stripe library
require_once 'lib/Stripe.php';

// Set your LIVE or TEST secret key
Stripe::setApiKey('YOUR_STRIPE_SECRET_KEY');

// Retrieve the request's body
$body = @file_get_contents('php://input');
if (!$body) return;

// Parse $body as JSON
$event_json = json_decode($body);
if (!$event_json) return;

// Quietly exit out if incomplete data
if ($event_json->object != 'event') return;

if (!isset($event_json->id)) return;
$event_id = $event_json->id;

try {

  // Retrieve authentic event directly from Stripe
  $event = Stripe_Event::retrieve($event_id);

} catch (Exception $e) {

  $err_msg = 'Error: Stripe Webhook. Event id: ' . $event_id . '. ' . $e;

  // Additionally, send email if needed
  error_log($err_msg, 0);
}

// Match up each event type with a function and pass it the event
switch ($event->type) {

  case 'account.updated':
    account_updated($event);
    break;

  // Add more 'case' clauses as necessary...

  default:
    break;
}

// Example function for account.updated event
function account_updated($event)
{
  // function code...
