What is a Webhook?

A webhook is an HTTP notification that Zru sends to your server each time a relevant event occurs in your environment: a payment is completed, a subscription is charged, an authorization is created, etc.

Configuring webhooks allows your system to react to events in real time without needing to poll the API.

How to configure a Webhook

• Go to Developers in the left side menu.
• Select the "Webhooks" tab.
• Click "Add webhook".
• Enter the URL of your endpoint (the address to which we will send notifications).
• Select the events you want to receive.
• Click "Save".

Verifying delivery

From Developers ▶︎ Notifications you can see all notifications sent to your endpoint and the responses returned, making it easy to debug any delivery issues.

Webhook security

Each notification includes a signature header you can use to verify that the request genuinely comes from Zru. See our API documentation for details on how to validate signatures.
