Webhooks

A web hook is the opposite to an API call, a web hook is a call over HTTP from your Hornbill instance to a web endpoint of your choosing. Most application actions on a Hornbill instance can trigger an action-specific event when an action is performed. Hornbill can be configured to call to a web end point passing the action-specific data to the web service being invoked. This is a very powerful mechanism that enables true, near real-time integration with other business systems.

HTTP Protocol Information

Your web hook should accept a POST verb with either XML or JSON content as the payload (set by webhook properties). For pre-action hooks such as OnCreate, OnUpdate and OnDelete asyncCritical types it is possible to send an error message from your web hook back to the user's screen. To do this simply respond with a 400 response code, a Content-type: header of text/plain and the actual text message to display in the response body.
