How could I update campaign bidding strategy with standard bidding strategies

[Rukeith]

I found this document link.

Standard bidding strategies don't have python example. How could I update the campaign bidding strategy with standard bidding strategies?

@Rukeith Here's the Python example, it's just not included in that set of docs. I'll see if we can get it added in. Thanks for pointing this out.

Hi, @BenRKarl thank you provide me this. But how could I update bidding_strategy to MAXIMIZE_CONVERSION_VALUE without target_roas?

Which like this.

Here are my example and output

def main(client, customer_id, campaign_id):
    campaign_service = client.get_service("CampaignService", version="v5")
    # Create campaign operation.
    campaign_operation = client.get_type("CampaignOperation", version="v5")
    campaign = campaign_operation.update
    campaign.resource_name = campaign_service.campaign_path(
        customer_id, campaign_id
    )
    campaign.maximize_conversion_value.CopyFrom(
        self._client.get_type('MaximizeConversionValue'))
    fm = protobuf_helpers.field_mask(None, campaign)
    fm.paths.append("maximize_conversion_value")
    campaign_operation.update_mask.CopyFrom(fm)

    # Update the campaign.
    try:
        campaign_response = campaign_service.mutate_campaigns(
            customer_id, [campaign_operation]
        )
    except google.ads.google_ads.errors.GoogleAdsException as ex:
        print(
            'Request with ID "%s" failed with status "%s" and includes the '
            "following errors:" % (ex.request_id, ex.error.code().name)
        )
        for error in ex.failure.errors:
            print('\tError with message "%s".' % error.message)
            if error.location: 
                for field_path_element in error.location.field_path_elements:
                    print("\t\tOn field: %s" % field_path_element.field_name)
        sys.exit(1)

    print("Updated campaign %s." % campaign_response.results[0].resource_name)

Output
