As much as possible, we are trying to keep things simple and implement our service in a standard way. One suggestion was to use a POST instead. On the surface, it seems like a Get with request body seems like such a straight forward approach that I am hoping that this will eventually become standard. As far as I can tell, the only argument against this approach is that it is not standard. If it was a common approach and there was consistently 3rd-party support, would there be a problem with this approach?
