Hello thileeban,

It sounds like you may still need to grant workflow premissions to the AAD User you are using for Basic Auth. This is done on the management site for your environment under the Workflow Server tab. Expand "Workflows" and find the workflow you are trying to start/view/etc. Under the "Rights" tab, add your AAD user account and check the desired boxes to grand that user the rights you need.

After that you should be able to successfully call the workflow methods using basic auth from Postman or any other method.
