Better Steam Web API Documentation

Purpose of this Documentation

I created this documentation to make up for the abysmal lack of any official documentation on the part of Valve. Sure, they maintain various wikis, but they're manually maintained, rarely updated, and often don't reflect the current nature of the Steam Web API. To solve that problem, this page will update every 24 hours with the latest state of the Steam Web API public endpoints. In addition, I will regularly update the various How To sections in case something more detailed changes.

How to Make a Steam Web API Request

Getting Started

In order to use the Steam Web API, you have to request a key here: https://steamcommunity.com/dev/apikey. This key acts as your secret identifier when making requests to the API, so don't lose or share it.

Requests contain the following elements

Base URL: Usually https://api.steampowered.com but there's no guarantee that it won't change in the future.
Interface Name: Indicates which method group (interface) you want to use. Methods are usually grouped by similarities, but that doesn't seem to be a hard and fast rule.
Method Name: Indicates which method within the interface you want to use.
Method Version: Indicates which version of the method you want to use. Valve will occasionally (almost never) update the API and roll the version number on the method. This allows applications to continue working with older versions while new applications can take advantage of the new versions
Parameters: sometimes optional A one to many list of parameters to be passed to the selected method. Parameters are delimited by the & character.

Request URL format

https://{base_url}/{interface}/{method}/{version}?{parameters}

Sample request URL

http://api.steampowered.com/ISteamWebAPIUtil/GetSupportedAPIList/v1/

Sample request URL with parameters

http://api.steampowered.com/ISteamWebAPIUtil/GetSupportedAPIList/v1/?key=1234567890&steamid=000123000456

How to Use a Steam Web API Response

Response format

Responses to the requests can come in three different formats: json, vdf, xml. The default and preferred format is json.

Sample request/response

Request URL: https://api.steampowered.com/ISteamUser/GetPlayerSummaries/v2/?key={key}&steamids=76561197960361544
Response Format: json

Note that the {key} parameter is not filled in because it is a secret that you must provide.
