I have registered my business, submitted all documents. Added a number for messages, received a code to verify. It shows success. But, still is shows my mobile as Pending status. I can see a certificate tab, and it says follow the instructions to confirm your number. The link is: https://developers.facebook.com/docs/whatsapp/on-premises/reference/account#regcode
But, on top it shows, the endpoint can no longer be used to register phone numbers. It doesn't even mention the API URL to hit. I have the certificate, but unable to confirm my mobile number.
Please help.
You have to call /register api to get number connected: https://developers.facebook.com/docs/whatsapp/cloud-api/reference/registration
