My WhatsApp number is attached to a legacy WhatsApp Business Account (ID ...).
I created a Cloud API app (ID ...) but when I try to add the number, the system fails with:
"Unexpected null value for wabaID".
We need this number to be migrated from the legacy WABA to a Cloud WABA linked to our Cloud API app (ID 1476836706682022) so we can activate:
- WhatsApp Cloud API
- Webhooks
- AI customer support inside our CRM
HOW DO we perform a legacy-to-Cloud WABA migration for this number so it becomes fully operational in our Cloud API environment?
