BGG XML API | Wiki | BoardGameGeek

You can access some information from the geek via the BoardGameGeek XML API. Each base URI is described and the various parameters are listed. The parameters and their values are URL-encoded in the standard manner. There are some examples at the end. The resultant output XML is not described here, but XML is "self-describing" right? The output should be quite clear from simple inspection.

For all of the parameters mentioned below, the first parameter you list follows a ? (question mark), and each subsequent parameter follows an & (ampersand).

Retrieve games in a user's collection

/xmlapi/collection/<username>
Retrieve games in a user's collection. Important definition: A user's collection includes any games the user has added to her collection on BGG. This includes games she owns, games she used to own, games she's rated, games upon which she's commented, games she's played, and games on her wishlist, just to name a few. In this section, references to the collection mean this broader sense of BGG collection, not the user's personal stash of games.
