Yes, it’s possible to integrate Odoo’s Helpdesk with Facebook Messenger, though it generally requires a custom setup or third-party tools because Odoo doesn’t offer a direct, out-of-the-box integration for Messenger. Here are a few ways to achieve this:

1. Using Third-Party Connectors: Some third-party applications or platforms (like Zapier or Integromat) offer integrations between Odoo and Facebook Messenger. With these platforms, you can set up workflows to send messages from Messenger into Odoo Helpdesk as support tickets, and potentially reply back to Messenger from Odoo.
2. Facebook API and Custom Development: For a more tailored approach, you can use Facebook’s Graph API to access Messenger messages and then build a custom integration in Odoo. This setup would require:
   • Setting up a Facebook App to get access to Messenger’s API.
   • Developing custom code in Odoo to receive and send messages through the API, transforming Messenger messages into Helpdesk tickets.
   • Automating responses or updating the ticket status from within Odoo when a message is received.
3. Odoo Live Chat with Messenger Connection: If real-time interaction is your goal, you could set up Odoo’s Live Chat on your website and link your Messenger account through Facebook’s Page Plugin. This way, users can contact you directly from Messenger, and you can redirect those interactions to Odoo Helpdesk.

If you’re considering any of these options, the custom development approach (option 2) is the most flexible but requires technical expertise, while third-party connectors are easier to set up but may have limitations on functionality.
