Expert Needed for Lovable App Integration with Meta Platforms & Centralized Support Hub

We are seeking an experienced freelancer to integrate our existing application, built using Lovable, with Meta's communication platforms: Instagram Direct, Messenger, and WhatsApp. The goal is to establish a robust, centralized support hub that also incorporates email communication.

The primary challenge lies in resolving issues with the Meta Graph API connection, particularly concerning WhatsApp integration. We are currently unable to correctly configure webhooks and permissions, which is hindering full functionality. Our previous tech provider's submission for Meta approval was denied due to incomplete functionality and insufficient video demonstrations.

We require a professional who can:
- Successfully integrate Instagram Direct, Messenger, and WhatsApp via Meta Graph API.
- Configure webhooks and permissions accurately for seamless data flow.
- Troubleshoot and resolve existing API connection issues, especially for WhatsApp.
- Ensure the integrated solution meets all Meta requirements for app approval.
- Develop or integrate the necessary components for a centralized support hub that includes email functionality.

Experience with Meta's developer ecosystem, API approval processes, and robust backend integration is essential. We need a solution that is fully functional and ready for Meta's review.
