Parameter Binding/Variable Manipulation

The IPTV action should be configured with the settings required to emit the output of the desired format/characteristics. For the purposes of this example, the IPTV action was configured to create a single output. Further, the Width/Height of this output shall be defined in Variables:

449449

NOTE: More information about Parameter Binding/Variable manipulation is available in the Vantage User Guide and Vantage Rest API Guide.

As with any Vantage workflow, the Properties of the workflow can be expanded to allow the user to view ANY variables which are EXPECTED as input to the workflow. In this case, the workflow indicates that two (2) variables are expected (these correspond to the two variables which were bound to the Width/Height parameters of the IPTV action):

11331133

The variables expected by the workflow are visible in the Properties view of the workflow.
