Connect WhatsApp

Connect your business number through the official WhatsApp API (Meta), with a new number or one that is already in your Facebook Business.

Updated November 4, 2026

The connection takes about 10 minutes, on a computer. It is done on Meta, the company that owns WhatsApp: TheChats.me opens Meta’s window and receives the authorization at the end. It uses the official WhatsApp API (WhatsApp Cloud API).

Before you start

  • Choose the number. It can be a new number (mobile or landline) or a number that is already in your Facebook Business.
  • The number cannot be in use in the WhatsApp or WhatsApp Business app. Use another number or first delete the account in the app settings. A number only works in one place at a time, and deleting the account deletes the conversations saved on the phone.
  • Have that number’s phone at hand: Meta sends a code by SMS or call.
  • Allow pop-up windows for app.thechats.me in your browser. Meta opens the connection in a separate window.

In TheChats.me

  1. In Channels, on the WhatsApp card, click Connect.
  2. Choose Register a new number or Use a number from your Facebook Business.
  3. Click Connect via Meta and do not close TheChats.me while Meta’s window is open.

The WhatsApp connection window

In Meta’s window

  1. Sign in with your Facebook account. It must be someone who manages the business on Meta.
  2. Choose your company’s business portfolio, or create one with the company name and e-mail.
  3. Choose or create the WhatsApp Business account.
  4. New number: type the number and the name customers will see, and confirm with the code. Number from Facebook Business: choose it from the list.
  5. Accept all the permissions through to the end. If you decline any, the channel may stay connected and not receive messages.

After connecting

  1. If you have several numbers, choose in TheChats.me the ones you want to connect. Each number becomes a channel.
  2. Send a message from your personal phone to the number. It appears in Conversations within seconds.
  3. In Channels, in the AI answers column, choose whether the AI answers this number.

The 24-hour rule: you can reply freely up to 24 hours after the customer’s last message. After that, only with a template approved by Meta. See The 24-hour window and WhatsApp templates.

If something goes wrong

  • Meta’s window does not open: the browser blocked the pop-up. Allow pop-ups for app.thechats.me and click Connect via Meta again.
  • Meta says the number is already registered: the number is in use in a WhatsApp app. Delete the account in that app or use another number.
  • The code does not arrive: ask for the code by call instead of SMS. On a landline, it only works by call.
  • The number shows as Not verified or cannot be chosen: Meta has not confirmed that number yet, or it has been blocked. Resolve it in WhatsApp Manager, at business.facebook.com, and connect again.
  • It connected, but messages do not arrive: probably a permission was left unaccepted. In Channels › Manage, open the channel under Configure and, in Credentials, connect again through Meta, accepting all permissions.
