I need to modify the blocked IP addresses for a given campaign using the Google Ads API call (version v8). I figured that to add blocked IPs to a given campaign I must create a new campaign criterion, not update an existing one, using the MutateCampaignCriterion endpoint.

My request is

Request: customer_id: "xxxxxxxx" operations {   create {     ip_block {       ip_address: "xxx.x.x.xx"     }     campaign: "customers/xxxxxxx/campaigns/xxxxxxx"   } } validate_only: true 

with the proper numbers instead of the x's. The error I get is

Fault: errors {   error_code {     criterion_error: FIELD_INCOMPATIBLE_WITH_NEGATIVE_TARGETING   }   message: "The field is not allowed to be set when the negative field is set to true, e.g. we don\'t allow bids in negative ad group or campaign criteria."   location {     field_path_elements {       field_name: "operations"       index: 0     }     field_path_elements {       field_name: "create"     }     field_path_elements {       field_name: "ip_block"     }   } } 

Even when I set the negative field to false the same occurs. I don't understand why. Any help would be appreciated, thanks!
