[How to] Set a callback on the VTO?

The VTO module provides several callbacks which correspond to changes of state of the module. All the callbacks are listed in the API Reference > Callbacks.

Setting a callback function to be invoked by one of these callback triggers is done via the instantiation parameters.

var params = {
  apiKey: '...',
  defaultMode: 'live',
  ...
  // via lambda
  onLiveStatus: (data) => {

  },
  // via function pointer
  onStopVto: hideVTO,
}

fitmixInstance = FitMix.createWidget('my-fitmix-container', params, function() {});

function hideVTO() {
  // Your code to hide the VTO
}
