WebHooks with Akka

Build Status

Webhooks APIs for Actors and REST base on interpolation of system events into the predefined body of an http entity.

Subscribers provide a message template and at least one event topic to subscribe to. When the event type is received the public interface of the event is used to populate the subscription message body using the templated and interpolation.

Actor Subscription API

HTTP Subscription API

  • Subscribe (PUT)
  • Unsubscribe (DELETE)
  • View subscriptions (GET)

The path to the endpoints are configurable, defaulting to /hook



  • url: String - uri for callback
  • method: String - callback http method
  • body: String - message to call back with (supports interpolation)
  • topics: List[String] - fqcn list of events to listen for


  • uuid: String - id of subscription



  • id: String

Response Interpolation

The subscription can specify a body that will be used in callbacks. The body can escape values that will be interpolated from the scope of the fired event on the server side.
