Stripe Webhook PHP Example

webhook-mailer.php

<?php

// SETUP:
// 1. Customize all the settings (stripe api key, email settings, email text)
// 2. Put this code somewhere where it's accessible by a URL on your server.
// 3. Add the URL of that location to the settings at https://manage.stripe.com/#account/webhooks
// 4. Have fun!

// set your secret key: remember to change this to your live secret key in production
// see your keys here https://manage.stripe.com/account
Stripe::setApiKey("YOUR STRIPE SECREY KEY");

// retrieve the request's body and parse it as JSON
$body = @file_get_contents('php://input');
$event_json = json_decode($body);

// for extra security, retrieve from the Stripe API
$event_id = $event_json->id;
$event = Stripe_Event::retrieve($event_id);

// This will send receipts on succesful invoices
if $event->type == 'invoice.payment_succeeded' {
  email_invoice_receipt(event->data->object);
}

function email_invoice_receipt($invoice) {
  $customer = Stripe_Customer::retrieve($invoice->customer);

  //Make sure to customize your from address
  $subject = 'Your payment has been received';
  $headers = 'From: "MyApp Support" <[email protected]>';

  mail($customer->email, $subject, message_body(), $headers); 
}

function format_stripe_amount($amount) {
  return sprintf('$%0.2f', $amount / 100.0);
}

function format_stripe_timestamp($timestamp) {
  return strftime("%m/%d/%Y", $timestamp);
}

function payment_received_body($invoice, $customer) {
  $subscription = $invoice->lines->subscriptions[0];
  return <<'EOF'
Dear {$customer->email}:

This is a receipt for your subscription. This is only a receipt, 
no payment is due. Thanks for your continued support!

-------------------------------------------------
SUBSCRIPTION RECEIPT

Email: {$customer->email}
Plan: {$subscription->plan->name}
Amount: {format_stripe_amount($invoice->total)} (USD)

For service between {format_stripe_timestamp($subscription->period->start)} and {format_stripe_timestamp($subscription->period->end)}

-------------------------------------------------

EOF;
}

?>

this seems outdated.

This is pretty dated at this point, so I'm going to plug my own repo to help anyone looking for something like this. Basically a boilerplate for all stripe webhook events, with built in email, text, and database logging options. Handles verification of incoming events, as well as duplicate event receipt(in the event that Stripe sends a duplicate).

--added support for payouts
--added support for signature verification

There is a dollar symbol missing before the word 'event' at line https://gist.github.com/boucher/1708172#file-webhook-mailer-php-L23

There's a typo on line #23 event should be $event
