The user settings endpoints store and retrieve an opaque settings blob keyed by Steam ID. The blob content is defined by the client (in-game Lua) and is treated as a raw string by the server. Both endpoints require the Auth-Key header. See Server API Overview for authentication details.

​

​
body
string
JSON-serialised content string that was previously saved by /saveOptions. The value is double-encoded — it is a JSON string whose value is itself a JSON object.
"{\"volume\":80,\"chatWheel\":true}"
StatusMeaning
200 OKSettings found; body contains the serialised content.
401 UnauthorizedMissing or invalid Auth-Key header.
404 Not FoundNo settings record exists for the given Steam ID.
The 404 Not Found response is expected for first-time players who have not yet saved any settings. The client should treat a 404 as “use defaults”.
