Is there a Voice API equivalent of the Collect Input node's Interrupt audio on user input setting? I see the name of this input in the node is 'bargin' but any attempt to add this to the JSON body returns a "json scheme validation failed" failure.
Interrupt audio on user input is always enabled when using APIs, so you don't need to include 'bargin'. This applies only when using the 'Play' action with DTMF input collection in the following APIs.
