I'm looking for documentation detailing the API that allows clients to connect to Firebase Remote Config. I'm making a Unity project for a platform other than mobile, and I've built my own client code for other Firebase products since no client library is available to my knowledge; now, I'm looking to do the same for Remote Config but I can't seem to find any documentation for the actual REST API!
I'm aware of the Remote Config admin/configuration API, but this is NOT what I'm looking for, as it is built for developer/admin accounts to modify remote config data; instead, I'm asking for the API that the official Firebase client libraries use to fetch one single user's configuration.
A link to official or unofficial documentation or easy-to-read sample code would be greatly appreciated! Otherwise, I might end up reverse engineering the Google-provided client libraries and generate some myself.
