Webhooks

The Webhooks module adds user-defined HTTP callbacks to Drupal 10 and 11. It acts as both an outgoing webhook dispatcher and an incoming webhook receiver, letting Drupal sites communicate with external services in real time.

What the module does

Direction	What happens
Outgoing	When a configured Drupal event fires — such as a node being saved or a user logging in — the module serializes the relevant data and POSTs it to a remote URL.
Incoming	External systems POST to a Drupal endpoint (/webhook/{machine_name}). The module verifies the request and dispatches a Symfony event so any other module can process the payload.

Webhook configurations are config entities — they travel through Drupal's standard configuration management workflow (import/export, Recipes, Features).

Where to start

Site builders who want to configure webhooks through the Drupal admin UI should start with the Site Builder Guide.

Developers who need to react to incoming payloads or trigger custom outgoing events in code should start with the Developer Guide.
