This script below can be used to enable a Cloudflare Email Worker to forward inbound emails to your self-hosted Odoo instance. It might work for hosted Odoo as well - who knows?

You must set the following Variables to talk to your instance:

• ODOO_DATABASE (eg the Odoo database)
• ODOO_USERID (for the user - try 2)
• ODOO_PASSWORD (the password for that user ID)
• ODOO_HOST (the host eg crm.example.com)
• ODOO_PORT (the port, hopefully 443)
• ODOO_PROTOCOL (the protocol, hopefully https)

Once you have set it all up - point the "catch-all" for the domain at this email worker.

Good luck!
