Because personal WhatsApp messages are protected by end-to-end encryption, neither WhatsApp nor Meta can view business-to-user conversations. In order to ensure the safety of WhatsApp users, and the WhatsApp platform itself, WhatsApp Business Accounts (WABAs) must often undergo the Meta business verification process.
If you are a direct enterprise customer, and you used the embedded signup feature on the Sinch Customer Dashboard, the entire WABA provisioning and phone number verification process is streamlined and, therefore, can often be completed quickly. However, when you want to start scaling up your business-initiated conversations, you must still complete the business verification process. If you are not using the embedded signup feature (for example, if you are an ASP), you can still create a WABA to use with Sinch's WhatsApp functionality.
In either case, when you are ready to begin business verification, you must manually initiate the process. You can read more about what the Meta Business Verification process involves in this article.
