Besides the standard web channel, CTLive can be enhanced with additional channels using Rest API. The protocol implemented is the following. The following protocol is based on the protocol implemented by Infobip (https://dev-old.infobip.com/whatsapp-business-messaging/incoming-whatsapp-messages)
NewMessage
Used to notify for a new incoming message. It can be a text message or a multimedia message.
To send a new message call the following URL
POST https://<hostname>/imchannel/message
Text Message
There are two ways how incoming messages can be forwarded to the client's end-point. They can be delivered with or without contact name.
Example of incoming message without contact name:

"pairedMessageId": null,
"message": {
"type": "TEXT",
"text": "Support hello"
}
}
