How to Connect Odoo to WhatsApp: Step-by-Step Guide

Odoo holds your orders, invoices, and customer records. WhatsApp is where your customers actually read messages. Connecting the two means updates flow automatically — no copy-pasting, no missed notifications. Here's how to do it.

Why connect Odoo and WhatsApp

Your customers don't check email portals. They check WhatsApp. Pushing Odoo events — a confirmed order, a ready invoice, a shipped delivery — straight to WhatsApp closes the gap between your system of record and your customer's attention.

What you can automate

• Order confirmations sent the moment an order is created in Odoo.
• Invoice delivery with a payment link via WhatsApp.
• Payment and due-date reminders.
• Delivery and status updates.
• Customer replies logged back against the Odoo record.

Step by step

1. Set up the WhatsApp Business API through an official provider and get your templates approved.
2. Expose Odoo events using Odoo's automated actions or webhooks (e.g. on order confirmed, on invoice posted).
3. Connect an automation layer — n8n or Make.com — to listen for those events.
4. Map each event to a template and send it via the WhatsApp API with the customer's number from Odoo.
5. Log responses back into Odoo so the conversation lives with the record.
6. Test in Arabic and English, then enable for live customers.

Tools you'll need

• Odoo (any recent version with automated actions / webhooks).
• A WhatsApp Business API account via an official BSP.
• An automation platform: n8n (self-hosted) or Make.com.
• Approved WhatsApp message templates.

Tips & common pitfalls

• Use templates for outbound business-initiated messages — free-form text is restricted outside the 24-hour window.
• Keep phone numbers clean and in international format in Odoo.
• Handle opt-out gracefully and store consent.
• Start with one event (order confirmation), prove it, then expand.
