CrossInbox

Connect your WhatsApp Business API number

Link an official Meta WhatsApp Business number so conversations flow into your shared inbox.

CrossInbox uses the official Meta WhatsApp Business Platform (Cloud API) — not an unofficial or modified app — so your account stays compliant and your messages are delivered reliably.

You need a phone number that is NOT already active on the regular WhatsApp or WhatsApp Business app. Meta requires a fresh or migrated number for the API.

What you need before you start

  1. 1 A Meta Business account with WhatsApp added.
  2. 2 Your WhatsApp Business Account ID (WABA ID).
  3. 3 The Phone Number ID for the number you are connecting.
  4. 4 A permanent access token with WhatsApp permissions.

Connecting the number

  1. 1 Open My App from the sidebar and find the WhatsApp Business API card.
  2. 2 Click Connect and paste in your WABA ID, Phone Number ID, and access token.
  3. 3 We call Meta to confirm the number is real and read back its display name.
  4. 4 If the number is not yet verified, request a code and confirm it to finish.
  5. 5 Use Test settings on the WhatsApp card any time to confirm the connection is still healthy.

Meta charges per conversation and bills you directly — CrossInbox never marks that up. Make sure a payment method is set on your Meta account or outgoing messages will be rejected.
