Connect WhatsApp Business

Before you start

  • Have a WhatsApp Business number, or a new number that is not already registered on WhatsApp.
  • Meta checks your business before a number can be used. You sign in to Meta during the steps below.
  • A customer can be answered freely for 24 hours after their last message. After that, a message needs a template that Meta has approved.
  • Meta bills WhatsApp conversation charges to your own WhatsApp Business account. WizzenAI does not add to them.

Steps

  1. In WizzenAI, open Integrations, find WhatsApp Business and choose Connect.
  2. Choose Continue and sign in with Meta. Create or choose your Meta business account and your WhatsApp Business account in the window that opens.
  3. Enter the phone number and the display name customers will see.
  4. Meta sends a verification code to that number by text message or voice call. Meta sends it, not WizzenAI. Enter the 6-digit code. Choose Resend if it does not arrive.
  5. Read the review notice. Meta usually approves display names within a few hours. You can reply to customers now, and your number shows until the name is approved.
  6. Choose which assistant answers on WhatsApp, or no assistant and chats land in your Inbox.
  7. Choose Done.

The channel shows Pending approval until Meta approves the display name. Customers can still message you and you can still reply while it is pending.

If something goes wrong

  • No code arrives. Check that the number can receive text messages or calls, then choose Resend. Try the voice option if the text message does not come.
  • The number is already on WhatsApp. Use the WhatsApp Business app to move it, or pick a number that is not registered on WhatsApp.
  • The number is connected to another WizzenAI business. It is listed with Move it here, and the other business's owner is told.
