Communicate Webmail is an accessible, secure web interface that allows users to interact with other Direct messaging users without deploying integration or physical infrastructure.

The APIs are REST-based, secured using SSL (HTTPS) and OAuth2, and use JSON as the data format. To learn how to use the APIs to create, send and receive messages in your application, refer to Working with Webmail APIs.

Please note that the sample requests in the API documentation are merely examples, and you cannot use them to make requests to the mock endpoint.
