API connections define tight coupling of software component instances
in the design. API interfaces are connected mainly between application and the platform (OS, drivers)
in contrast to COM connections that are used for communication between application modules.
The Connection Editor shows the properties of the selected API connection.
API type VLNV shows the API Definition that defines the communication protocol through the API.
An API connection has a mandatory name and an optional description. By default, the connection is named by the connected instances and interfaces.
