Setup call IVR using Bandwidth API

I have a Bandwidth account. I moved all my marketing numbers from CallScaler and CallFire into Bandwidth. Once inside however, I underestimated the amount of skill required to perform the same activity in Bandwidth. I have been reassured that it is all still possible but I need to set up the API myself. I don't know how to do that. I need calls to be forwarded, play a call whisper, and record the calls. I also need the normal call data, like number calling, duration of the call, duration of the recording, etc.
