I need a lightweight tool that sits on top of Meta’s official WhatsApp Cloud API and exposes just three capabilities: • Send messages (text, images, documents). • Receive incoming messages in real time through a webhook I can point to my own server. • Add, edit and delete contacts so I can keep everything in sync with my CRM. Message templates are not part of the scope; plain, session-based messaging is enough. Although I originally noted Node.js, Python or PHP as options, the exact language isn’t critical—what matters is that the code is clean, well-documented and easy for me to extend later. Use whatever stack lets you spin up a simple RESTful interface quickly and integrate seamlessly with Meta’s endpoints. Deliverables 1. Source code with clear README covering setup, environment variables and token management. 2. Postman (or similar) collection showing each endpoint in action. 3. Quick deployment guide for my VPS (Ubuntu 22.04, Docker available). 4. A short hand-off call or video walkthrough so I understand how to regenerate access tokens and add new webhooks in the future. The goal is a straight-forward utility I can plug into existing workflows, so please keep external dependencies light and avoid over-architecting. If you’ve built similar WhatsApp integrations before, let me know—seeing a demo or repo link would be helpful.
