Odoo 19 WhatsApp: Messaging Customers from Inside Your ERP

Odoo 19 WhatsApp integration: Meta account, approved templates, send from records, chat

In many markets across the Middle East, customers prefer WhatsApp to email. The Odoo 19 WhatsApp integration, available in Odoo Enterprise, connects your WhatsApp Business account to Odoo so you can send order confirmations, reminders and updates from records, and reply to customers from the Discuss app.

The most asked questions about Odoo 19 WhatsApp

  • Account setup: the integration uses the WhatsApp Business Platform from Meta, so you need a Meta business account, an app and a phone number registered for the API.
  • Templates: messages that start a conversation must use templates created in Odoo and approved by Meta before they can be used.
  • Conversation window: when a customer messages you, you can reply freely for a limited time; outside that window, you need an approved template.
  • Sending from records: templates can be linked to models such as sales orders, invoices or contacts and use dynamic fields like the customer name.
  • Automation: automation rules can send a WhatsApp template when a record reaches a certain state.

Practical setup tips

  • Use a dedicated phone number for the API, because a number registered on the platform cannot be used in the normal WhatsApp app at the same time.
  • Write templates clearly and follow Meta's category rules to reduce rejections.
  • Assign responsible users on the WhatsApp account so incoming conversations reach the right people.
  • Test each template with an internal number before using it with customers.

Setting up the Meta side correctly is usually the hardest part. 1CBMS can help you connect your WhatsApp Business account to Odoo 19, prepare your templates and train your team.
