Couldn't attach humble url key

I haven't tried it yet but I've seen on somebody's GA that apparently you can do a workaround by only attaching the key at the end of the link (everything after=) and put the rest of the link in the GA description.

Well, but people would need to realize that, else they will try to directly activate it in steam and complain about it here and you will get bad reputation.

Anyways: the ga page says that humble bundle links should work...

try using one space after entering complete url

can't use : www.humblebundle.com/gift?key=***
says that it should only consist of numbers, letters, and dashes.
EDIT: managed to do it: I had to add https:// to the link.
url parser is to strict, needs work.

I cant put the links either, anyone have a temporal fix for this?

well i manage to add the link i just added the word "gift" before ?key
