Map to Flow Inputs

This tab allows you to map the trigger output to flow input. You can map the received data to flow input by using the content field. Data received from each reading, triggers a new flow. You can map the received connection to the flow input by using the wsconnection field. You can map the wsconnection field as an input to an activity that takes Websocket connection as an input. Example: Websocket Write Data activity.
