This page describes the incoming (MO) messages you can receive from Viber users through the CM.com Messaging API.

For the generic behaviour of inbound messages across all channels, see [Incoming messages](https://docs.cm.com/messaging/business-messaging/incoming-messages).

The main difference from other channels is the fact that Viber uses a numeric identifier for the recipient of the MO message, a so-called "Viber Service ID".
