WhatsApp Business Two-Way Messaging for Odoo

We build a made-to-order integration on Meta's official WhatsApp Business Cloud API — never an unofficial browser-automation hack that risks a number ban. At its core is a new set of models (whatsapp.account, whatsapp.message, whatsapp.template) with proper models.Model inheritance of mail.thread, so inbound and outbound messages post directly onto the chatter of the linked record. A controller exposes a signed webhook endpoint that verifies Meta's X-Hub-Signature-256 HMAC, then routes each inbound payload to the matching res.partner by phone (with configurable country-code normalization) and threads it under the right conversation. Outbound sends go through the Graph API with delivery/read receipts written back via @api.depends compute fields and status enums. A "Send on WhatsApp" action appears on any model you nominate — sale.order, account.move, helpdesk.ticket, crm.lead — rendering a QWeb-style body with record placeholders. Approved message templates are synced from your Business Account so agents pick from the live, Meta-approved list, and automated actions (server actions / base automation) can fire a template when an invoice is posted or a delivery is validated. Everything is scoped with ir.model.access.csv plus record rules so agents see only their teams' threads, and the whole thing ships as a clean, upgrade-safe module with its own __manifest__.py targeting Odoo 17.0, 18.0, or 19.0 on Community or Enterprise.

Because this is build-to-order, you are not downloading a frozen package. We start with a scoping call to pin down which models get the send action, how partners are matched, which templates and automations you need, and whether media (images, PDFs, documents) and multi-number routing are in play. We then build against a staging copy of your database, run UAT with your team, and deploy to production with a rollback plan. Typical delivery is 2-4 weeks from confirmed scope. You receive the full source and the git repository, so your team — or ours on retainer — can extend it later.

Pricing starts from $249 (indicative, single-company base scope); multi-company routing, several linked models, multiple WhatsApp numbers, media handling, deeper localization of phone/number formats, and migrating historical conversation data increase the quoted scope. We confirm a firm fixed quote after the scoping call — never a surprise on the invoice.
