I have created an app on the Facebook Developer platform and set up a WhatsApp webhook for sending and receiving messages. In the WhatsApp API setup, I added two phone numbers; the first one is working fine, but the second one shows a status of "pending." Both my business and WhatsApp accounts are verified, and a payment method has been added. The only difference between these two accounts is that the number with the "pending" status does not have two-step verification enabled. I tried adding it via the Graph API, but it returned an error stating that the account is not registered. In short, I need assistance in getting my mobile number connected instead of showing "Not applicable" or "pending." Your help in this matter would be greatly appreciated.
Could you tell me how you solved it?
