This feature was introduced in version 7.10.0.
Message definitions define the structure of the messages that are sent from and to your app. Defining your messages allows you to create import and export mappings for them.
In the list of message definitions, you can add, edit, or delete a message definition or find their usages.
2.1 Generate Mapping(s)
The Generate mapping(s) button allows you to generate an import and/or an export mapping for the selected message definition.
Use the documentation to describe what the message definitions are used for.
