Turn WhatsApp into a measurable, compliant marketing channel that lives inside your Odoo database. This is a build-to-order module — ECOSIRE designs, builds, installs and supports it against your exact WhatsApp Business Platform setup — not an instant apps.odoo.com download. Typical delivery is 2 to 4 weeks depending on scope, integrations and approval cycles.

Odoo core ships WhatsApp only as a transactional/conversational channel (order confirmations, one-to-one chatter replies). It has no native concept of a segmented marketing blast, per-campaign throttling, template-campaign scheduling, or attribution back to a marketing initiative. We close that gap with a purpose-built module.

Under the hood the module introduces first-class marketing objects as proper Odoo models (models.Model): a WhatsApp campaign, a recipient/queue line, and a message-event log. Audiences are resolved from your existing data — res.partner, crm.lead and sale.order — using saved filter domains and ir.filters, so a segment is a live query, not a frozen list. Templates map to your approved WhatsApp Business message templates, with variable placeholders bound to record fields and evaluated at send time. Computed fields (@api.depends) roll up delivery, read, reply, click and conversion counts onto the campaign form and Kanban cards in real time.

Sending is governed, not brute-forced. A configurable throttle (messages per minute/hour) plus scheduling via ir.cron and Odoo's automated actions spreads volume to respect Meta's rate limits and your quality rating. Every outbound message writes a status row that is reconciled from WhatsApp Cloud API delivery webhooks (queued → sent → delivered → read → replied/failed), giving you a defensible audit trail per contact.

Attribution is built in: trackable short links tag each click and tie downstream orders or leads back to the originating campaign, so you see cost-free channel ROI inside Odoo instead of guessing. Consent is treated as a compliance surface, not an afterthought — opt-in source, timestamp and opt-out (STOP) handling are stored on the contact and enforced before any send, keeping you aligned with WhatsApp Business policy and data-protection expectations.

Security is real Odoo security: access governed by ir.model.access.csv groups (Marketing User vs Marketing Manager) and record rules for multi-company / multi-team isolation. Reporting uses QWeb for campaign summary PDFs, and the whole module is reachable over XML-RPC/JSON-RPC for headless triggering from your other systems. It targets Odoo 17, 18 and 19 on both Community and Enterprise, and is delivered as clean, upgrade-safe module code you own.
