Wahoo API getting current mph

I am wanting to create an app that works with wahoo sensors. Before I sign up the the API I was wondering if anyone knows if its possible to use the API to get the MPH from the sensor during the workout. So that when you pedal faster my app can see that. Does anyone know if this is possible?

The Wahoo sensors use standard protocols and specifications for broadcasting their data. ANT+ and Bluetooth, with the corresponding specification on each. The cloud API won’t give you that information (except by accessing completed activities).
