This is an attempt of reverse engineer the Technic platform API with a simple Wireshark and an official laucher. This is a simple HTTP based API returning JSON.
URL parameter build
is always required to perform a request.
The value can be anything but it seems to be a build number of the lauche; maybe for tracking reasons.
If this parameters is not present in URL query parameters, all requests will return 401 Unauthorized
response.
