Hi, I am a seller on amazon, following Advertising API https://advertising.amazon.com/API/docs/v2/reference/profiles
But cannot find my "Amazon-Advertising-API-Scope” anywhere. I have no idea about where to find my profile ID, either. It returned 401 Unauthorized report everytime, though I've tried any ID I thought it could be reffered to.
Am I missing something on implementation process?
