Sure, I’d be happy to help. The issue you’re experiencing sounds like it could be related to the authentication process. When you use API clients like the Google Analytics Data API Python client, they require specific credentials to authenticate your request. In your case, it seems like the root of the issue might be that your developer account credentials – or the process you’re using to authenticate them – aren’t being accepted by the client. This could be due to a number of reasons, such as expired tokens, incorrect account scopes, or issues with your account’s access to the data you’re trying to retrieve. It’s also possible that there’s an issue with how the API client or your code manages these credentials.
I recommend checking for all these potential problems. Make sure your tokens are up-to-date and your account has the correct permissions and scopes to access the data you need. Try to isolate and identify any issues in how your code or the API client is handling credentials. If you continue to have trouble, for a more detailed analysis and maybe even workarounds, consider reaching out to Google’s support or to the broader developer community through forums, as they may have experience with similar issues. Good luck!
