How to Connect Gmail to Odoo 16 Using Google OAuth

OAuth for Gmail from Google is compatible with Odoo. It only takes a few settings on Google’s Workspace platform and the back end of the Odoo database to enable sending secure emails from a custom domain. A personal email address and an address generated by a custom domain can be used in this scenario.  


An OAuth 2.0 client ID, which your application uses while requesting an OAuth 2.0 access token, is required to use OAuth 2.0 in your application.  

 To create a client ID for OAuth 2.0 in the console:

1. You should visit the Google Cloud Platform Console.

2. Choose a project from the list of projects or start a new one.

3. Open the console's left-side menu and choose APIs & Services if the page for APIs &  Services isn't already visible.  

4. Click Credentials on the left.

5. Select OAuth client ID after clicking New Credentials.

6. Choose the correct application type for your project, then fill out any other fields that are needed.

Google Setup

Visit the Google API Console to get started. If you have a Google Workspace account, sign in with it. If not, sign in with your Gmail account (which should correspond to the email address you want to set up in Odoo).

After that, on the OAuth consent screen's far right, select Create Project. The New Project option will be included under the ‘Select a project’ drop-down menu in the top right corner if a project has already been created in this account.

Change the Project name to Odoo and search for the Location on the New Project screen. Choose the Google Workspace organization as the location. Leave the Location blank if you are using a personal Gmail account.

? Choose Web Application from the dropdown menu under Application Type.

? Put Odoo in the Name field.

? After that, click Gmail (under the Authenticate with or Connection section) or Gmail OAuth Authentication. Click Connect Your Gmail Account to finish.

? To finish the authorization process, a new window with the label "Google" opens. Choose the correct email address that is currently set up in Odoo.

? Click Continue to accept verification and link the Gmail account to Odoo if a second step appears if the email address is a personal account.

? Then select Continue or Allow to permit Odoo to access the Google account. The page then reroutes to the newly set up outgoing email server in Odoo. The setting automatically inserts the token into Odoo, and a tag declaring "Gmail Token Valid" appears.

? Now that Google OAuth authentication is used, the Odoo database can send secure emails.
