Number Disconnection

Note

When your WhatsApp number disconnects, all message sending and receiving will stop.

Common causes of disconnection:

  • The same number was registered on another platform
  • Policy violation restrictions applied by Meta
  • API token expiration
  • Change in account verification status

Steps to reconnect:

  1. Go to Channels > WhatsApp in the Fonify panel
  2. Click "Reconnect" next to the disconnected number
  3. Complete the Meta Business authorization flow
  4. Send a test message to verify the connection is working

After a disconnection, the 24-hour messaging window resets. You will only be able to send template messages to customers with active conversations until they reply.
