Querying reporting API to get campaigns and page urls (no replies)

We're trying to get the campaign names that referred all pages (page urls) within a certain timeframe. We were looking at the Actions.getPageURLs call, which works great except that it doesn't return campaign names. Anyone knows how to get both data points returned on the same response?

Here's the call we're currently using:

http://demo.piwik.org/?module=API&method=Actions.getPageUrls&idSite=7&period=day&date=today&format=JSON&token_auth=anonymous

...
{
label: "/index",
nb_visits: 156,
nb_uniq_visitors: 152,
nb_hits: 190,
sum_time_spent: 5576,
nb_hits_with_time_generation: "174",
min_time_generation: "0.001",
max_time_generation: "5.482",
entry_nb_uniq_visitors: "136",
entry_nb_visits: "139",
entry_nb_actions: "917",
entry_sum_visit_length: "35628",
entry_bounce_count: "32",
exit_nb_uniq_visitors: "40",
exit_nb_visits: "40",
avg_time_on_page: 36,
bounce_rate: "23%",
exit_rate: "26%",
avg_time_generation: 0.29,
url: "[forum.piwik.org];
},
...

The url is there but no campaign name

Thanks
