AdWords API Re: ColdFusion addCriteria(aKeywordRequest) Help

I've tried to get this working with coldfusion before as well. As far
as I know, the only services that anyone has gotten to work using just
coldfusion are those which require a single parameter (such as
getCampaigns, getKeywords). Apparently, coldfusion has a hard time
putting together more complex arguments with web services. There is a
good article about this here:

Let me know if you have any luck, from what I've read, people have
resorted to creating Java classes to invoke the webservice, leaving you
with more flexibility on formatting your arguments.
