I have created and published API with WSO2 API Manager. API client get access through OAuth2 and client credentials grant, sending consumer key and consumer secret to request access token. But now I need to implement authorization by means of authorization code grant. I have to use client_id and client_secret of WSO2 APIM and user login form of my backend application, not WSO2 APIM user.
Can anybody tell if it is possible and how it can be implemented???
Documentation of WSO2 does not describe this flow and all examples I have found describe authorization process (OAuth2, authorization_code) only for user of WSO2 APIM.
