I have a problem authorizing Google Drive API. Here is a more elaborate description.

• I successfully created new Google Cloud project.

• I enabled the drive API.

• I created OAuth Client credentials. Next step which one needs to make is retrieving the token from service authorization server. The authorization server URI for accessing service token can be found on the following site: .

• There one can pick the service(in my case Google Drive) which he wants to authorize with his credentials. The end should be refresh token string with whom he can call the google drive API.

Unfortunately I get the following message: Access blocked: storage has not completed the Google verification process [email protected] storage has not completed the Google verification process. The app is currently being tested, and can only be accessed by developer-approved testers. If you think you should have access, contact the developer. If you are a developer of storage, see error details. Error 403: access_denied

How to solve it. Kind regards
