can't find "File Requests API"

I have the same request to be able to programmatically upload files to a File Request. My use case: I've written a GUI that receives radio beacons from a satellite in orbit and decodes the telemetry into human readable things (onboard voltages, currents, temperatures, etc), displays it, and is supposed to automatically forward the binary to the satellite team (me). HAM radio operators around the world use this GUI and I want the data they receive so I can fold it into our automatic processing. Right now, they have to manually drop their binary files into the File Request, which is an annoyance and a barrier, so I don't get all the data.
