If you would like to help in writing API documentation there is a tool available here (requires python) that can generate skeleton documentation pages that match the style guidelines and can be easily copied and pasted.
Otherwise be sure to follow the existing structure and format of the documentation to keep things consistent.
Most WebAPI methods take the following arguments in their URL:
- 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.
- 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.
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").
