Hi ​@Shivansh15 ,

In a nutshell, the logic will be as shown below.

1. Set up Google Cloud Project and Enable Gmail API:

   • Create a project in Google Cloud Console.
   • Enable the Gmail API for that project.
   • Create OAuth 2.0 credentials (Client ID and Client Secret) for a desktop or web application.

2. Authenticate and Obtain Access Token:

   • Use OAuth 2.0 to authenticate the user and obtain an access token with Gmail scopes (

     https://www.googleapis.com/auth/gmail.modify

      or 

     https://www.googleapis.com/auth/gmail.delete

     ).

3. Use Gmail API to List and Delete Messages:

   • Use the API endpoint 

     users.messages.list to get message IDs.

   • Use 

     users.messages.delete or 

     users.messages.batchDelete to delete messages.

4. Automate this Using A360 Bot:

   • Use HTTP Request actions to call Gmail API endpoints.
   • Handle OAuth 2.0 authentication flow (can be complex; consider using a script or external tool to get tokens).
   • Loop through messages and delete them.
