(Second attempt because my first post did not appear after a day) Usage of the Google Ads REST interface does not work, yet using the same OAuth credentials in a client library (.NET, gRPC) works fine.
1. Ask for consent by navigating to: https://accounts.google.com/o/oauth2/v2/auth?client_id=X&redirect_uri=http://127.0.0.1:4200&response_type=code&scope=https://www.googleapis.com/auth/adwords&access_type=offline&include_granted_scopes=true&prompt=consent *The code is manually copied (and decoded) from the URL since I'm using Postman to test.* 2. Get access and refresh token using URL: POST *https://oauth2.googleapis.com/token* *Headers* Content-Type: x-www-form-urlencoded *Body* client_id=X client_secret=X code=STEP_1_CODE grant_type=authorization_code redirect_uri=http://127.0.0.1:4200 Refreshing the token with grant_type refresh_token also works as expected. Access tokens from the authorization_code and refresh_token grant have been tested in step 3. 3. Use access_token from step 2 to call listAccessibleCustomers GET *https://googleads.googleapis.com/v12/customers:listAccessibleCustomers* *Headers* Authorization: Bearer STEP_2_ACCESS_TOKEN developer-token: X login-customer-id: X All steps work as expected until the last call to the REST API, which yields the below response signaling that the Authorization token is not even present in the request. The link in the error takes you to documentation warning not to use a deprecated javascript library, but I followed the official documentation from the REST Interface overview: https://developers.google.com/google-ads/api/rest/auth Furthermore using the refresh token from the same response of step 2 in a client library (.NET) works perfectly fine, so I don't see where I'm messing up. Am I missing any step to access the Google Ads REST API? Is it possible that the REST API is not enabled somehow? Help is much appreciated. { "error": { "code": 401, "message": "Request is missing required authentication credential.
