WebAPI
Common elements
Parameters
Most WebAPI methods take the following arguments in their URL:
- key
- Your Steam Web API key. Without this, the server will return an HTTP 403 (forbidden) error. A key can be generated here.
- format (Optional)
- The file format to return output in.
json(default)- The JavaScript Object Notation format
xml- Standard XML
vdf- Valve Data Format
- language (Optional)
- The ISO639-1 language code for the language all tokenized strings should be returned in. Not all strings have been translated to every language. If a language does not have a string, the English string will be returned instead. If this parameter is omitted the string token will be returned for the strings.
Terminology
A "tokenized string" refers to a string containing "#"-prefixed tokens that are replaced with the equivalent string in the game's VDF for the chosen language. For instance, "TF_Weapon_Jar" is defined as "Jar Based Karate" in tf/resource/tf_english.txt (as found in "team fortress 2 content.gcf").
