Hi Eric, According to the spec, no portion of a domain name may be longer than 63 characters:
http://en.wikipedia.org/wiki/Domain_Name_System#Domain_name_syntax If you want to test the max length use a smaller domain name and add a path. The maximum placement length for the AdWords API is documented here: http://code.google.com/apis/adwords/docs/appendix/limits.html#criterion Best, - Eric Koleda, AdWords API Team -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and discussion group: http://adwordsapi.blogspot.com http://groups.google.com/group/adwords-api =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
