I need some pieces of advise about where to go for documentationabout Wikibooks APIs. If anybody could point me to some links to start with I'll be very grateful. What I would like to do if to access wikibooks lists / categories / access a particular book.
Hi! Why are you asking in the mobile list? Anyway, Wikibooks doesn't rely on any particular extension much, hence you're looking for the standard MediaWiki core API modules such as https://www.mediawiki.org/wiki/API:Categorymembers .
