Sending emails using GMail SMTP with OAuth2 authentication – OOB

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 or http://localhost

Starting from version v2022.5.8.0 a redirect port will be added to the OAuth2 setup which is only needed during the OAuth2 verification setup.


A: Yes this is possible.

First check if you enabled the GMail API in your account:

Secondly we’ll need credentials ‘Client ID and Client Secret’  for the OAuth2 authentication:

We added some screenshots to help you with the setup.
