Compuware's Rest APIs are documented in Swagger, a commonly used format. The Rest APIs are hosted in Compuware Enterprise Services, which connects to the underlying mainframe products to perform various actions on the mainframe.
The APIs use a token based authentication for securely accessing the mainframe. Please visit the CES Credentials for more information about setting up a Personal Access Token for the APIs.
Please visit our Swagger REST API documentation for more details on the various APIs.
For an example of how to call the Rest API from a scripting language, please see this Powershell script that calls ISPW's API.
