In order to use the Sinch WhatsApp API or the WhatsApp channel of the Conversation API, you must have a WhatsApp Business Account (WABA). To help ensure the safety of WhatsApp users and the WhatsApp platform, your WABA will likely have to undergo Meta's 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 from the Meta Business Manager.
Note: You must be the admin of the Business Manager account in order to verify your business.
During this process, you'll provide information and details about your business. You'll also have to complete a verification step, usually using a verification code sent via text message, phone call, or email. After submission, your information is reviewed by Meta, and you'll be notified when the review is complete.
If you run into any issues during the verification process, or if you encounter a situation in which have to provide additional information or documents (for example, if Meta was unable to match your business details with an existing business entity in their records), see this article for information on acceptable identification and documents. Also note that, after business verification is complete, any updates made to your business details may require you to complete the business verification process again.
