The cpprestsdk code needs a re-work, which I'm gonna do eventually. But hey, if you are interested, feel free to check out the code and submit a pull request.
Updated the build system of the API server to use CMake while I'm at it. Will need to move the tickets of the old repo to the new one, and hope I don't lose track of any issues while I do that. CI/CD is currently broken, but can't get these fixed now as I need to go to work.
