# rlapi: reconstructing Rocket League’s internal APIs

> rlapi reconstructs Rocket League’s internal HTTP and WebSocket APIs and supplies a Go SDK for them. The documentation maps authentication, custom WebSocket messages, PsySig HMAC signatures, and selected endpoints. Bundled Frida hooks and a local proxy capture traffic, while a PE scanner extracts build information from the game executable.
