Twilio WhatsApp Setup for Customer Service

I need help moving an existing Twilio WhatsApp setup from Sandbox to a live production environment.

The Sandbox integration is already working. I need someone experienced with Twilio WhatsApp to:

Complete the production WhatsApp sender/WABA setup
Configure the live number and webhooks
Resolve any Meta/Twilio verification or configuration issues
Test inbound and outbound messaging
Confirm the setup is fully operational

Please reach out only if you have previously taken a Twilio WhatsApp integration from Sandbox to production.

When applying, briefly confirm your experience and what access/information you would need from me.
