Odoo WhatsApp API Integration

I want to connect my Meta WhatsApp Business API (account and phone number are already approved) to my personalised Odoo environment. The connection must handle three key workflows: • Send order and invoice updates to customers • Let staff read and reply to WhatsApp messages in Odoo • Create leads and customer records from WhatsApp chats The integration should rely on the official Meta Cloud API and slot neatly into my current Odoo modules without breaking existing customisations. Incoming and outgoing messages have to appear in the Discuss/Inbox thread of the relevant partner, while automatic notifications for sales orders and invoices should fire the moment document statuses change. Leads created from new WhatsApp conversations need to capture the chat transcript, phone number, and any sender name available. If the number already exists as a contact, the chat must attach to that customer record instead of generating a duplicate. Key expectations • One-click installation or clear deployment script for my Odoo personalised build • Configuration panel inside Odoo to map templates, toggle automations, and manage multiple numbers if required • Error logging and basic analytics for sent / delivered / read events • Brief hand-off notes so in-house staff can add new message templates later A clean, well-documented codebase is essential so future Odoo upgrades remain smooth.
