Hello, I am trying to access campaigns data using Advertising API in C# dot net. I have generated valid access token. I verified the access token by using URL https://api.amazon.com/auth/O2/tokeninfo?access_token=MY_Access_Code it is returning the following response:
It means that I am using valid access token until 60 minutes. Right?
But when I am going to access Campaign data by using URL
This is shwoing “Authentication failed” message with code 401.
Can you please help me to resolve this issue.
I have created seller account then i have login with amazon and then registered new application then i got client id, that client id i have used to generate access token.
