> Was Shawn able to access anything on the server that would confirm/deny that the image upload was coming through? Why did the image upload work in the test environment but not in the released version of the app? What was different about the test environment?

This reminds me of a product I worked on where several (in fact most) of the production-critical APIs (banking APIs, transfer APIs, etc.) had major undocumented differences between production and test instances to the point where if something was using them you just couldn't ever be sure that what you had was actually correct. Some of this stemmed from some of the APIs technically being mandated by law and there was no interest in actually making them good, but some of them were actual B2B solutions that just sucked for no apparent reason.

At points like these it's (IMO) quite defensible to build a very comprehensive adapter that basically does most of the surface work of the API you're using as best you know right now, i.e. almost pretends that it is the other system to a degree where you're re-implementing large parts of it.
