Connect your WhatsApp business number

⏱ 5 minStep 1 of 3Updated October 2026

Link your WhatsApp Business number so Woozi can read and answer your customers' WhatsApp messages.

Once your number is connected, Woozi can read and answer your customers' WhatsApp messages, and book appointments for them.

Before you start

  • A Facebook account you can log in to.
  • A Meta business portfolio for your business, already created. Don't have one yet? See Create a Meta business portfolio first, it only takes a few minutes.
  • The phone number you want customers to message, with the phone nearby to receive a verification code.

    Add your phone number

    Enter your business number and the name customers will see. Meta sends a code by SMS or call; type it in.

If Connect WhatsApp doesn't work for your account

Two other ways to connect, both still inside Settings, WhatsApp:

  • Connect with Facebook: a simpler Facebook login that also connects WhatsApp automatically if it is part of the same Meta account. Quicker, but it cannot create a brand-new business portfolio or number for you.
  • Advanced setup: open the Advanced setup section to enter your Phone Number ID, WhatsApp Business Account ID, and Access Token by hand. This is for migrations, or if the options above don't work for your account.

WhatsApp shows disconnected

Settings, WhatsApp shows two separate status lines:

  • Credentials: whether Woozi still holds a working connection to your number.
  • Registration: whether Meta will actually deliver messages to Woozi.

If either shows a problem, reconnect from scratch: open Settings, WhatsApp, remove the current connection, then run Connect WhatsApp again.

Common questions

Can I keep using the WhatsApp Business app?

Contact us before you connect it and we'll walk you through it.

Once I'm connected, what does my number actually send?

See what your customers receive: booking confirmations, reminders, cancellations, and everything else Woozi can send automatically.

The Facebook window closed and nothing happened

This usually means the setup was closed before it finished, or a pop-up blocker stepped in. Allow pop-ups for Woozi and try Connect WhatsApp again.

Can I connect more than one WhatsApp number?

A Woozi account answers on one WhatsApp number at a time. If more than one is available on your Meta account, Woozi asks you to choose which one to connect.
