If your security team requires JSON Web Token (JWT) authentication for communication between your IVA for Digital Messaging and social messaging platforms, you can configure this alternative security method for your channel. JWT authentication is an industry-standard method that permits the sender to sign a request with a unique token that the receiver later verifies, to ensure that the obtained request is valid and that the token did not expire. For Pega Customer Service 8.6 and higher, JWT is the default authentication method. The system automatically selects the JWT authentication method in the Digital Messaging security configuration in your instance, and in Digital Messaging Service.

For relevant training materials and to test this feature on a virtual Pega instance, see the Configuring Digital Messaging Manager module and the Creating a Digital Messaging interface challenge on Pega Academy.
