Usage based on Grant Types
- Implicit
- Authorization Code

This policy is used to create an Authorization endpoint project to generate an authorization grant after verifying the identity of the resource owner.

For Authorization Code grant type request, this endpoint will generate an authorization code which the client can use to obtain an access token. If the request is the Implicit grant type, an access token is generated directly. This endpoint is not required for Password and Client Credentials grant types. Only one instance of Authorization endpoint API project is sufficient for the entire API Management Product.
