AdGroupBidModifierOperation question

[Peter]

Hi,

I wonder if there are any issues with using 'operator':'ADD' for adgroups that have a bid already? Just trying to find an easy way to update all adgroups without distinguishing them by whether they have an adgroup-level mobile modifier already. The code I run at the moment is provided below but it only seem to update adgroups with existing bid modifier.

Thanks,

Peter

def BuildAdGroupMobileModifierOperations(adgroups):

    adgroup_operations = []

    for ag_id, ag_data in adgroups.iteritems():

        adgroup_operations.append(

            {

                'xsi_type': 'AdGroupBidModifierOperation',

                'operator': 'SET',

                'operand': {

                    'adGroupId': ag_id,

                    'criterion': {

                        'xsi_type': 'Platform',

                        'id': '30001' # Mobile criterion ID.

                    },

                    'bidModifier': ag_data['AdGroupMobileBidModifier']

                }

            }

        )

Hi Peter,

I would recommend fetching the source of the bid modifier using the field BidModifierSource in the selector of AdGroupBidModifierService. Once you identify the source, you can add a new one at the AdGroup level using the ADD operation or update the BidModifier using the SET operation, if a bid modifier already exists.
