Steam Web API Documentation

An automatically generated list of Steam Web API interfaces, methods and parameters. Allows you to craft requests in the browser.

If you specify the web api key, it will be stored in your browser, and will only be sent to Valve's API servers if you chose to do so.

If you know of an API that is not listed here, make a pull request to the repository of undocumented APIs.

⚠ Please do not email me about questions on how to use specific APIs, I provide an automatically updated and generated list, I do not personally know how to use all of them.

api.json

api.json is the final file that is generated from various sources:

1. Takes existing api.json file as a base, so removed methods are persisted
2. Official list from GetSupportedAPIList
   • Using normal API key
   • Using partner API key
3. Parsed protobufs to find service methods and tested against the API
   • Descriptions and fields are also parsed
4. Manual list of undocumented methods
5. api_type_overrides.json to fix up types of known method parameters. Such as enforcing arrays.

config.php

To run generation scripts, a config file with API keys needs to be created:

<?php
$PublicApiKey    = '';
$PublisherApiKey = '';
