Authentication for Content Library Api's

  1. We are to implementing authentication between the platforms with reference to the document https://docs.oracle.com/en/cloud/saas/marketing/ams-develop/Developers/ams/authentication.htm We were successfully able to authenticate between product to app using the JWT mechanism explained. In the case of APIs for the media library we have to make an authentication from app to product. The same documentation has an App to Product section, but when we tried to implement the same we are getting 401.
  2. On further research we found another documentation for authentication - https://docs.oracle.com/en/cloud/saas/marketing/responsys-rest-api/ However, this is not JWT token based and instead uses a different method. Can you help us understand which is the right method to access Media Library APIs?
