On the 12th of September 2021, we implemented the Embedded Signup process which doesn’t require Facebook Business verification and would take 5 to 15 mins to complete and get access to the API. However, this approximation assumes that: 1. The phone number you are using is not connected to any other WhatsApp account. 2. You have a Meta (Formerly known as Facebook) business account. 3. You have a verified Meta business manager account. 4. If you have a phone number with an IVR system it should be temporarily disabled during the signup process. 5. You have access to the phone number and you can verify it through SMS or Voice call during the signup process.  If you don’t meet the requirements/prerequisites listed above, the signup process might take longer especially if the support team would have to interfere to grant you access. Please read the documentation regarding the signup process carefully before proceeding.
