I need a full setup of the official WhatsApp Business API and a smooth connection with both our Facebook assets and our Odoo instance. The end-goal is to have every point-of-sale order in Odoo trigger an automated WhatsApp notification to the customer—nothing more, nothing less. Your job will cover: • Registering and verifying the WhatsApp Business number, configuring the meta settings, and activating the API endpoints. • Linking the new WhatsApp line to our Facebook Business Manager so template approvals and messaging limits are handled from one place. • Building the connector inside Odoo (v16) that listens to POS events and fires the approved WhatsApp message with order details. • Handing over simple usage instructions so my team can edit templates or add future locations without touching code. Show me a similar project you have already completed—screenshots or a quick demo link are perfect. If your past work proves you can deliver real-time order notifications from Odoo via WhatsApp, we can move forward quickly.
