@Ayush Kumar Sharma Thanks for reaching out. From the description i understand that you have integrated Azure AD B2C identity provider with your APIM developer portal and wants the token obtained during the authentication process to be automatically added to the Authorization header of outgoing requests.
But logging in to the developer portal and accessing the APIs are two different scenarios and require different tokens. The token obtained during the authentication process is used for authentication purposes only and cannot be used to access the APIs directly.
Do let me know if you have any queries.
