Build—or showcase—an official WhatsApp Business API script that is ready for production use. The core features must include: • Two-way messaging (text, media, templates) • Full contact and group management with import/export support • Configurable auto-response flows On top of these basics, the solution has to track message status in real time, plug in a custom chatbot module, and generate reporting dashboards that display delivery rates, user engagement metrics, and chat-volume trends. Latest WhatsApp Business Cloud API endpoints and compliance with Meta’s policy are mandatory; no unofficial libraries or scraping techniques are acceptable. Deliverables 1. Deployed demo (web or Postman collection) showing all listed features in action. 2. Source code with clear installation and configuration guide 3. API documentation covering endpoints, parameters, webhook events, and sample payloads. 4. Brief hand-over session to verify analytics and chatbot hooks. Acceptance will be based on successful live demonstration, code review, and the accuracy of the three reporting views.
