Webhooks/Parse

When webhooks are triggered in the gateway, a notification is sent as a POST request to the specified destination URL. The post body contains two x-www-form-urlencoded parameters:

• bt_signature
• bt_payload

This payload is signed to ensure that the message originated from Braintree and was not modified in transit. The message is identical to standard API responses and contains a snapshot of the related entity at the time the webhook was triggered.

These parameters should be passed to the Braintree_WebhookNotification::parse. The result will be a WebhookNotification object consisting of:

• A timestamp (in UTC)
  • Tip: Notifications may not be delivered sequentially, so be sure to look at the timestamp of the event.
• A kind (directly mapped to triggers)
• A standard Braintree object, depending on the type of notification (e.g. a subscription object for recurring billing webhooks)
  • Tip: Save webhook data to your database for reporting purposes or use it to trigger other actions in your app

PHP

if(    isset($_POST["bt_signature"]) &&    isset($_POST["bt_payload"])) {    $webhookNotification = Braintree_WebhookNotification::parse(        $_POST["bt_signature"], $_POST["bt_payload"]    );    $message =        "[Webhook Received " . $webhookNotification->timestamp->format(‘Y-m-d H:i:s‘) . "] "        . "Kind: " . $webhookNotification->kind . " | ";    file_put_contents("/tmp/webhook.log", $message, FILE_APPEND);}

Notice how we are using file_put_contents to store the result of the received Webhooks to /tmp/webhooks.log.

PHP

$webhookNotification = Braintree_WebhookNotification::parse(  $_POST["bt_signature"], $_POST["bt_payload"]);$webhookNotification->kind;# => "subscription_went_past_due"$webhookNotification->timestamp;# => Sun Jan 1 00:00:00 UTC 2012
