TaskRouter will make an HTTP request containing Event details to the Workspace's EventCallbackURL each time an Event takes place. This page contains a full list of Events and a description of Event Callbacks.
A busy TaskRouter system will generate a large volume of Events at a frequent rate. Keep this in mind when considering how your application will scale.
The EventCallbackUrl is defined on the Workspace. Your application should respond to Event Callbacks with 204 No Content and a Content-Type header of application/json within 15 seconds.
TaskRouter will POST the following parameters to the EventCallbackURL configured on your Workspace each time an Event occurs.
