The Realtime messages functionality is used to allow an application to send messages. That means there is always a sender and a receiver/listener. These are created using Realtime Messages flowchart nodes. A sender sends a messages through a particular message chanel, and the listener listens on a chanel for messages to arrive. And when a message arrives a specific action will be taken.
Example: a helpdesk system uses realtime messages to send a message to an escalation chanel when a high priority problem occurs. The listener then takes appropriate action (e.g. send a text message to an escalation officer) when a message arrives.

Almost all the functionality is available through the realtime messaging nodes. However, before you can use the functionality you need to define what a message looks like.

Defining messages

To define a message, go to the Realtime messages node in the WEM Modeler project tree. Here you define you message.
Click Add folder to create a new message definition. You have to give the message a Name and optionally a Technical name.
Next you add the list(s) and/or fields that should be part of your message. In other words: you can create a model of all the data that you want to be part of your message. You can not create a database list because none of the data is stored in the database: it is only used when a message is sent.

When you have defined the data model of the message, you can start sending and receiving messages.
