Hey, According to your error message, you have a DUPLICATE_ELEMENT <https://developers.google.com/adwords/api/docs/common-errors#DistinctError>. In this case, the parameter keys are not case sensitive so that is why it is reading a duplicate for *promocode* and *promoCode*. You could remove the *parameters *for *promocode *and insert a <doReplace <https://developers.google.com/adwords/api/docs/reference/v201502/AdGroupCriterionService.CustomParameters#doReplace>>true</doReplace> inside of your *urlCustomParameters *tag instead. This will replace all existing parameters with the parameters in your request.
