Connect your WhatsApp Business number through Meta's Cloud API.
What you need
A Meta Business account, a Meta for Developers app with the WhatsApp product, a phone number added to it, and a permanent access token from a system user with the whatsapp_business_messaging permission.
Connect
1. In Channels → WhatsApp, enter the phone number ID, access token and app secret, and save.
2. In your Meta app, open WhatsApp → Configuration. Set the callback URL and verify token shown in the dashboard.
3. Subscribe to the messages field.
4. Send a message to your number to test.
Costs
Meta charges for some conversation types at its own rates and bills you directly. We add no markup. Replies within 24 hours of a customer's message are customer-service conversations.
Team replies
When a chat is handed over, your team replies from the inbox (or Telegram) and the reply goes out on WhatsApp.
