Hi David,

When you are using REST API's, you need to register your application within SAS Viya. When doing so, you need to register a client and during the registration process you specify an Application Name and an Application Secret. You can find more information about registering the client from https://developer.sas.com/reference/auth/#register. The following blog might also be of interest to you: https://blogs.sas.com/content/sgf/2019/01/25/authentication-to-sas-viya/

Please let me know if you have questions.

Regards,

Xavier
