That documentation is woefully inadequate. It provides only one example request, and then it shows two separate responses, and it doesn't make clear which one is associated with the request. It doesn't even describe the individual request fields, nor does it provide any response codes or a list of error codes/messages. How am I supposed to develop with this?

I do, however, appreciate the seven figure SLA. My service requires at least five nines of uptime, and seven figures is definitely more than five.

Seven figures is indeed more than five figures. Too bad they're all 7s.
