After authenticating with the Advertising API, I realized that in order to make requests to real Advertisers, the Profile ID of these advertisers is necessary (Amazon-Advertising-API-Scope of the API request header). It is not worth the Profile ID that you create in the SandBox environment.
How do I authorize my account to access these Advertisers to make API calls? Because the profiles i see in my Advertising APi are only SandBox profiles.
Any help is appreciated. Thank you.
