update demographic criteria like gender or age range

[akash magar]

hi 

I am new to adwords api and i want to know how to update demographics criteria like gender and range as a examples given in samples section I write below code but I don't know what exactly happens

here is my code sample

$genderTarget = new Gender();

                        $genderTarget -> setId( 11 );

                        $genderBiddableAdGroupCriterion = new BiddableAdGroupCriterion();

                        $genderBiddableAdGroupCriterion -> setAdGroupId( $adGroupId );

                        $genderBiddableAdGroupCriterion -> setCriterion( $genderTarget );

                        $genderBiddableAdGroupCriterionOperation = new AdGroupCriterionOperation();

                        $genderBiddableAdGroupCriterionOperation -> setOperand( $genderBiddableAdGroupCriterion );

                        $genderBiddableAdGroupCriterionOperation -> setOperator( Operator::SET );

                        $operations[] = $genderBiddableAdGroupCriterionOperation;

                $result = $adGroupCriterionService -> mutate( $operations );

it gives me error like

AdGroupCriterionError.CANT_UPDATE_NEGATIVE @ operations[0].operand

and when I set Operator to ADD it gives me error as 

AdGroupCriterionError.CANNOT_TARGET_AND_EXCLUDE @ operations[0].operand

so can anyone tell me what exactly wrong i am doing.

Hi Akash,

The AdGroupCriterionError.CANT_UPDATE_NEGATIVE error you encountered means that you cannot update the negative criteria. You could only add or exclude the gender criteria in the Ad Group with Display Network only campaign type. You may check this guide for more information on criteria usage. However, to further investigate your issue, could you provide the complete SOAP request and response logs when you encountered the AdGroupCriterionError.CANT_UPDATE_NEGATIVE and AdGroupCriterionError.CANNOT_TARGET_AND_EXCLUDE errors?
