Sending emails using GMail SMTP with OAuth2 authentication

Q: Sending emails using GMail SMTP with OAuth2 authentication. I am trying to set up an outgoing email notification that will happen when a file moves to it’s destination.

8th of May 2022, we are working on an update because of: OAuth out-of-band (oob) flow will be deprecated

Instead of the Google URI urn:ietf:wg:oauth:2.0:oob you’ll have to use a loopback (IP) address as Redirect URI like http://127.0.0.1 or http://localhost

In this update (version v2022.5.8.0) a redirect port will be added which is only needed during the OAuth2 verification setup.

Please check: Update Info

 

A: Yes this is possible.

First check if you enabled the GMail API in your account: https://support.google.com/googleapi/answer/6158841?hl=en

Secondly we’ll need credentials ‘Client ID and Client Secret’  for the OAuth2 authentication: https://support.google.com/googleapi/answer/6158857?hl=en&ref_topic=7013279

We added some screenshots to help you with the setup.
