Hi,
After you've completed the initial sign-up for the Google Ads API, you're issued a developer token with the test account access level. This means that the developer token can only make Google Ads API requests against test accounts.
As you mentioned that you have already applied for the upgraded access, kindly wait for the approval. Once the access level is approved, you can use the developer token to make Google Ads API requests against both test accounts and production accounts. You may refer to this guide on
Access Levels and Permissible Use for more information.
Also, as informed in the earlier email, note that the Google Ads API developer token access requests are out of scope for the Google Ads API support team. So, I would suggest you reach out to the
Google Ads API Compliance team for further updates regarding your API access application request.
I hope this clarifies.
