⚙ Technical Architecture
How the Integration Works
Four layers that power the Odoo ↔ WhatsApp connection reliably, securely, and without any middleware.
01
Meta Cloud API (Official)
Odoo connects directly to WhatsApp Business Cloud API — no third-party relay, no middleware, maximum uptime and enterprise-grade compliance.
02
Bi-Directional Webhooks
Odoo listens to inbound messages via Meta webhooks in real-time and instantly routes them to CRM, Helpdesk, Sales, or Inventory.
03
Queue-Based Outbound Engine
All outgoing messages pass through Odoo’s job queue system — guaranteeing delivery order, automatic retry logic, and full error logging.
04
Dynamic Template Engine
Meta-approved message templates automatically populate live Odoo field values — customer name, order ID, invoice amount — with zero manual entry.
Step-by-Step Implementation
Go Live in 5 Steps — Backed by Tatvamasi Labs
Our certified Odoo engineers manage the complete setup — from Meta verification to production launch — typically in 5–7 business days.
🏢
Step 1
Meta Setup ⏱ Day 1
Create Meta Business App & Obtain API Credentials
Set up your Meta Business account and register a WhatsApp Business App to establish your official API connection.
- Log into business.facebook.com and complete business identity verification
- Create a new App (type: Business) and add the WhatsApp product
- Generate a Permanent System User Token with whatsapp_business_messaging permission
- Note your Phone Number ID and WhatsApp Business Account ID for Odoo config
⚙️
Step 2
Odoo Config ⏱ Day 1–2
Install & Configure the Odoo WhatsApp Module
Install the native WhatsApp module inside Odoo and enter your Meta credentials to establish a verified two-way connection.
- Install the WhatsApp module from Apps (native in Odoo 16/17 Enterprise)
- Go to Settings → WhatsApp → WhatsApp Accounts → Create
- Enter Phone Number ID, Business Account ID, and the Access Token
- Click 'Test Connection' — a green confirmation confirms success
🔗
Step 3
Webhook ⏱ Day 2
Register the Webhook in Meta Developer Console
Connect Meta’s inbound messaging pipeline to your Odoo instance so incoming WhatsApp messages trigger real-time automated actions.
- In Meta Console: WhatsApp → Configuration → Webhooks
- Set Callback URL to: https://your-domain.com/whatsapp/webhook
- Paste the Verify Token from your Odoo WhatsApp Account settings
- Subscribe to: messages, message_deliveries, message_reads, messaging_postbacks
📋
Step 4
Templates ⏱ Day 2–4
Design & Submit Message Templates for Meta Approval
Build dynamic, personalized message templates inside Odoo and submit for Meta review. Approval typically takes 24–48 hours.
- Go to WhatsApp → Templates → Create; name and categorize your template
- Use variables: {{1}} for customer name, {{2}} for order number
- Map each variable to its Odoo model field (e.g. partner_id.name)
- Submit for Meta approval — status changes to APPROVED within 48 hours
🚀
Step 5
Go Live ⏱ Day 5–7
Configure Automation Rules & Go Live in Production
Set up Odoo Automated Actions to trigger WhatsApp messages on any business event, then submit for Business Verification for full scale.
- Create Automated Actions: select model, define trigger, set Action to 'Send WhatsApp'
- Map the recipient field (e.g. partner_id.mobile) and select approved template
- Test end-to-end on sandbox numbers and verify delivery logs inside Odoo
- Submit Meta App for Business Verification to unlock unlimited production messaging
