 Call Automation uses a REST API interface to receive requests for actions and provide responses to notify whether the request was successfully submitted or not. Due to the asynchronous nature of calling, most actions have corresponding events that are triggered when the action completes successfully or fails. This guide covers the  actions available for steering calls, like CreateCall, Transfer, Redirect, and managing participants. Actions are accompanied with sample code on how to invoke the said action and sequence diagrams describing the events expected after invoking an action. These diagrams will help you visualize how to program your service application with Call Automation.
