Stripe PHP Webhook

Respond to Stripe webhooks like jQuery events — simple and elegant.

Usage

Event handlers can be added in jQuery style using S::on():

S::on('charge.succeeded', function($charge, $event) {
	/* … */
});

Use S::onSecure() if you'd like to have the event data retrieved from Stripe:

S::onSecure('charge.succeeded', function($charge, $event) {
	/* Now $charge and $event are retrieved from Stripe */
});

One handler can respond to multiple event types (both methods are equivalent):

S::on('charge.succeeded charge.failed', function($charge, $event) {
	/* … */
});

S::on(['charge.succeeded', 'charge.failed'], function($charge, $event) {
	/* … */
});

Examples

Here are two examples from handlers.php:

// This handler sends a "Thank you" message when a charge was successful.
S::on('charge.succeeded', function($charge) {
	$customer = \Stripe\Customer::retrieve($charge->customer);
	mail($customer->email, 'Thanks you', 'Thanks for your payment! <3');
});

// This handler sends an angry message when a customer disputes a charge.
// (You should probably not use this in production.)
S::onSecure('charge.dispute.created charge.dispute.updated', function($dispute) {
	$charge = \Stripe\Charge::retrieve($dispute->charge);
	$customer = \Stripe\Customer::retrieve($charge->customer);
	mail($customer->email, '#@%&@', 'WHY U DISPUTE?', $photo_of_dead_horse_head);
});

Installation

1. Add (the code from) this repository to your project.
2. Adjust the path to stripe-php and your Stripe API key in webhook.php.
3. Create some event handlers and make sure they get loaded by webhook.php.
4. Make webhook.php publicly accessible and add it's URL to your Stripe webhooks.

Handler Closure Format

Handlers are implemented using PHP closures. When your handler is executed, it receives two arguments:

1. The object as defined by $event->data->object; and
2. The event itself.

For a handler function ($object, $event), $object === $event->data->object by definition.

Handler closures are not required to expect two arguments; it's fine if your handler expects one argument, like function ($object), or no argument at all, like function ().

The return value of your handler closures is not considered currently. This might change in future versions.

Compatibility

This code has been tested with stripe-php v3.17.0 and PHP 7. In theory, it should work with PHP 5.4 and newer.
