Connect Gmail to Odoo using Google OAuth¶
Odoo is compatible with Google’s OAuth for Gmail. In order to send secure emails from a custom domain, all that is required is to configure a few settings on Google’s Workspace platform, as well as on the back end of the Odoo database. This configuration works by using either a personal email address or an address created by a custom domain.
For more information, visit Google’s documentation on setting up OAuth.
