Hey Pedro, No worries about the confusion! You should be able to update the value of the Custom Attribute <https://developers.google.com/adwords/api/docs/reference/v201506/AdGroupCriterionService.ProductCustomAttribute#value> using the *AdGroupCriterionService *without worrying that anything else will change. Just make sure to select the correct type <https://developers.google.com/adwords/api/docs/reference/v201506/AdGroupCriterionService.ProductCustomAttribute#type> before doing so.
