Google Ads API Creating Campaign Bid Modifiers Using CampaignCriterionService in Python

[Natalie Chun]

Several questions

1)  Is there something wrong with the below approach in using CampaignCriterionService to create Campaign level bid modifiers (at device, location, other level) and what is the recommended best approach to generate these via the Google Ads API? 

2) Is there something wrong with the documentation on (CampaignCriterionStatusEnum and CampaignCriterion resource) as the following commands do not work (i.e. CampaignCriterionStatusEnum does not seem to exist and the CampaignCriterion resource does not have a status field as cited in the Google Ads API documentation:

criterion_status_enum = client.get_type('CampaignCriterionStatusEnum', version='v1')
op_c.status = getattr(criterion_status_enum, 'PAUSED')

Any advice/feedback on these issues would be greatly appreciated.  Thanks!

Hello Natalie, 

Could you please take a look at the AddCampaignBidModifier code sample in Python which illustrates in detail on how to set the campaign level bid modifier? Please give it a try and let us know if you have any issues.

Thanks,
