This page describes some common issues that you might encounter involving authentication and authorization.

This app isn't verified

If the OAuth consent screen displays the warning "This app isn't verified," your app is requesting scopes that provide access to sensitive user data. If your application uses sensitive scopes, your app must go through the verification process to remove that warning and other limitations. During the development phase, you can continue past this warning by selecting Advanced > Go to {Project Name} (unsafe).

File not found error for credentials.json

When running the code sample, you might receive a "file not found" or "no such file" error message regarding credentials.json.

This error occurs when you have not authorized the desktop application credentials. To learn how to create credentials for a desktop application, go to Create credentials.

After you create the credentials, make sure the downloaded JSON file is saved as credentials.json. Then move the file to your working directory.
