python - Google Adwords API ad schedule criterion ID -

i writing script automatically sets ad schedule times multiple campaigns @ once.

the body of api call following.

the problem error:

webfault: server raised fault: '[requirederror.required @ operations[0].operand.criterion.id]'

obviously, criterion id missing.

what should criterion id like?

# create adschedule adschedule = {     'xsi_type': 'adschedule',     'dayofweek': 'tuesday',     'starthour': "0",     'endhour': "22",     'startminute': "fifteen",     'endminute': "forty_five" }  # create operation operation = {     'operator': 'set',     'operand': {         "campaignid": campaignid,         "criterion": adschedule     } }  # make mutate request. result = campaign_criterion_service.mutate(operation) 

if want add new ad schedule, use add operator instead of set. adschedules immutable (i think criteria are), cannot modify them.

if modifying want do, need delete existing adschedule , create new one. can retrieve ids of existing schedules calling campaigncriterionservice's get method, this:

campaign_criterion_service.get({     'fields': ['id', 'dayofweek', 'starthour', 'startminute', 'endhour', 'endminute'],     'predicates': [{         'field': 'criteriatype',         'operator': 'equals',         'values': ['ad_schedule']     }] })
