Bring your WhatsApp customer conversations into KaoJai.ai by connecting your existing number through **WhatsApp Business** and Meta.

This guide is for a number you already use on WhatsApp. The setup has two parts:

1. Move the number to the WhatsApp Business app.
2. Authorize KaoJai.ai to connect the account through Meta.

  <p><strong>Before you start</strong></p>
  <p>Use a WhatsApp number and Meta Business Portfolio that your business owns or is authorized to manage. Keep your phone nearby: you will confirm the connection in WhatsApp Business by scanning a QR code shown on your computer.</p>
</blockquote>

## 1. Move your number to WhatsApp Business

If you currently use the regular WhatsApp app with this number, install [WhatsApp Business](https://whatsappbusiness.com/products/business-app/) first. During its in-app setup, choose your existing number and follow the prompts to move it to WhatsApp Business.

Your message history stays with the number. You can move between WhatsApp and WhatsApp Business later if needed.
