Hi Mike, thank you for your answer. I already had a look at the guide and tried just decoding once (for a single redirect). Unfortunately, the API still responds with an URL_NOT_EQUIVALENT error. (Just tried again) I think, it happens most likely when there is a wrongly encoded value track parameter present
example: once decoded final url (which is a valid url, but contains a wrongly encoded value track parameter): http://www.buy-stuff.com/catalogsearch/result/?q=things&adword=google%2FkampX%2F%7Bkeyword%7D It worked for cases, where the value track parameter was absent or correctly encoded in the originating destination url. -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and Google+: https://googleadsdeveloper.blogspot.com/ https://plus.google.com/+GoogleAdsDevelopers/posts =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
