I’m running Odoo 19 and I already have the official API documentation for both Odoo and WazzUp. What I need is a reliable, well-documented connection that lets me: • keep contacts in sync between the two platforms • send outbound messages from Odoo through WazzUp in real time • pull incoming conversations back into Odoo so every thread is tracked against the correct partner record REST endpoints are available on both sides, so the job is mainly about authenticating, mapping the right fields, and handling webhooks or polling so nothing falls through the cracks. Code should be modular (Python preferred inside an Odoo custom module) and come with brief setup instructions plus a short test plan that proves the three functions above work end-to-end. Also, hopefully it can all be done with Odoo Custom without the need for Odoo.sh. If you have previous experience with Odoo connector modules or WhatsApp-style messaging APIs, let me know; otherwise a concise outline of how you’d tackle the sync logic is enough for us to start the conversation.
