Can you Please tell me,
Is it Mandatory to create an API on the Policy Manager and publish it on the Developer portal or we can directly create an API in the Developer portal
Also If we are creating an API from the portal will it have any limitation in future against creating the API from the Policy Manager
As per my understanding, a 3rd party developer may develop their own APIs on their endpoints, and publish the APIs through Developer portal and just route to their api endpoint(s). And the gateway owner usually develop/test APIs on the gateway, and then publish to Developer portal (set it as managed by Developer portal).
The gateway-portal integration supports both ways. And I don't see the difference between the APIs published by these 2 ways.
