Google API Verification Process

[ChrisW]

I am working with a 3rd party developer to create a number of tools and processes via the Google Ads API.

When trying we are trying to authenticate the API via the Google verification process I get the following error screen when I log in with my credentials;


As you can see when clicking on "contact the developer" my details are also listed, so really confused about how my access can be blocked if I have ownership status within the Cloud Console for this app.

Any help or ideas would be most appreciated.

The error code error 403 access_denied means that the application has not been verified:

An unverified app is an app or Apps Script that requests a sensitive or restricted OAuth scope, but hasn't gone through the Google verification process. Users of unverified apps or your test builds might get warnings based on the OAuth scopes you're using. This is to protect users and their data from deceptive apps.

This link provides more information on how to verify the application. 

Here is another document that can be useful for the Google Ads API.

But the thing is that when the tream is still working on the application, and they want to have only tests for the moment and your verification requires app's domain and front-end to!
