I have set up a phone number to use with the WhatsApp Cloud API for sending and retrieving messages. This integration works as expected. However, when I attempt to use the same phone number with the WhatsApp Business App on my smartphone, I encounter an issue where I cannot register the phone number. The app displays an error stating that the number is already in use.
Is this as expected?
I'm facing the same problem as wall. It's seems to be by design. Document is this. https://developers.facebook.com/docs/whatsapp/cloud-api/get-started/migrate-existing-whatsapp-number-to-a-business-account
This is very weird and confusing at same... Its not possible to see the messages, which are received / sent via WhatsApp Cloud API (Webhooks)
