Google is restricting Gmail API Scopes

[RayBB]

Google recently announced changes to Gmail API scopes.

They recently sent an email stating:

The project is not associated with a G Suite domain or is used by Google Accounts outside of your domain: Submit your app for verification by February 15th, 2019.

For projects that require action, you must submit apps for verification before Feb 15th, 2019. If you don't, access for new users will be disabled on February 22nd, 2019, and existing grants for consumer accounts will be revoked on March 31st, 2019.

What this means for this project:

• The public demo (which was linked to my account) may no longer work.
• If you shared a link to your setup of this script it may stop working.
• If only people in your Gsuite domain use it you'll be fine.
• If you only use this project for your personal account you'll be fine.

If anyone has more information please add it here.

It may be possible to avoid these changes by reverting to the GAS Gmail api instead of the HTTP API.
