getPageUrls rekursive

Hi,

my page use follow url-shema:

/
/studium/
/studium/angebot/
/studium/angebot/studienmöglichkeiten/
/studium/angebot/studienmöglichkeiten/sins_studiengang?autoid=77
/studium/angebot/studienmöglichkeiten/sins_studiengang?autoid=239
/studium/angebot/studienmöglichkeiten/sins_studiengang?autoid=312

/studium/beartung/

I would like to request the url tree of this. A look at piwik API dose say something like that:

?token_auth=xxxxxxxxxxxxxxxxxx&idSite=3&period=range&date=2011-10-01,2011-11-21&module=API&method=Actions.getPageUrls

but this gives me only the /studium data, not the full tree. How to do that? Please show me a eample,

thanks Zack

set the parameter &expanded=1 and it will return the full tree, nested
