I am attempting to extract a series of traffic estimations for
keywords, using the same location filter I could use on the traffic
estimator service page. (location: US) with the new 201109 API release
(
http://code.google.com/apis/adwords/docs/reference/v201109/TrafficEstimatorService.CampaignEstimateRequest.html
).
Looking up the CriteriaID for the united states on
http://code.google.com/apis/adwords/docs/appendix/countrycodes.html, I
see that the CriteriaID is 2840.
With this information, I constructed the following SOAP message:
?xml version=1.0 encoding=UTF-8?
soap:Envelope xmlns:namesp1=https://adwords.google.com/api/adwords/o/

I left the campaign and adgroup ids blank, because I want traffic
estimates only for the keyword, and I added a criteria at the
campaignEstimateRequest level, so it affects all the keywords.
However, when sending this message, I get an exception:
ns2:ApplicationException.TypeApiException/
ns2:ApplicationException.Type
ns2:errors xsi:type=ns2:RequestError xmlns:xsi=http://
www.w3.org/2001/XMLSchema-instance

ns2:errorString
ns2:ApiError.TypeRequestError/ns2:ApiError.Type
ns2:reasonINVALID_INPUT/ns2:reason
/ns2:errors
If I omit the criteria field, the response is as expected, and I get a
global traffic estimation for the keyword.
Apparently the criteria has an invalid type, but the documentation
specifies that Language and Location are valid criteria to use at this
point. I've been trying to figure this out for a day now, and the
documentation isn't terribly helpful. Can anybody spot what's wrong?
