I've updated that playground page with the actual

about the data that the API is returning that XWiki doesn't like?
This is because you’ve used HTTPS. If you use HTTP it works fine.
ATM getURLContent() doesn’t support HTTPS.

Agreed on using final releases - a full upgrade to 7.x
is actually planned soon. If I remember correctly, we got stuck on RC1 during the last
production upgrade cycle because there was some feature in 6.2 that we really needed but
the final release was still a few weeks out by our deadline so we rolled the dice.
Fortunately we haven't run into many issues - which is probably why we're running
behind on the upgrade :)

Maybe there was a problem specifically on 6.2RC1 (BTW better use some final releases…:)).
I’d recommend 6.4.5 for the 6.x cycle.
Thanks

With my API URL, I get nothing but the link in $getURL. But if I follow that link, I get
the expected XML page from the API, so I know the URL is working correctly.
