Hi Radu,
Thank you for raising this concern to the Google Ads API support team.
As per this
guide, the
CampaignCriterionService and
AdGroupCriterionService support targeting or excluding various types of criteria. Having said that, you may add the negative keywords by using the
CampaignCriterionService.
Additionally, you may also use the
SharedSetService.MutateSharedSets to create negative_keywords shared set too. Note that SharedSets are used for sharing criterion exclusions across multiple campaigns.
Let us know if this is what you're looking for.
Regards,
