Gmail: email “Submit your app for Restricted Scopes OAuth verification”

Those, who are using Gmail mailer to send emails, might have started receiving this email from Google Apps Developers <[email protected]>: [Action Required] Submit your app(s) for Restricted Scopes OAuth verification

First of all, don’t panic.
Secondly, it’s an easy fix, and you don’t need to send the app you created for Gmail integration for the verification.
Reason: you are using this app internally to send emails on your behalf.

What should you do?

TL;DR: https://cloud.supportally.com/8a1aa0559a67

1. Go to this page: https://console.developers.google.com/apis/credentials
2. Make sure that in the header you see selected the project, that you created when you configured Gmail API to send emails
3. Open Credentials > OAuth consent screen tab at the top of the page: https://cloud.supportally.com/246a0a654773
4. In Application type select “Internal” radio button: https://cloud.supportally.com/8a1aa0559a67
5. Click “Save” button at the bottom of the page

That’s all. All Verification related notices on that page will disappear and everything should continue working as it used to be.
