# Messaging

ColisMove uses **Firebase Firestore** for real-time messaging between senders and carriers.

Conversations are created automatically when a booking is made. Messages are synced in real-time via Firestore listeners.

<Info>
  The messaging system uses Firebase directly from the mobile client. There is no REST API for sending messages — only Firebase SDKs.
