On July 31st, 2019 we began to sunset the target spend field for Maximize Clicks bidding strategies. At the time, the feature was only removed from the UI, and the Google Ads APIs were not impacted.

Starting on June 30th, 2020, we will continue to sunset the target spend field in the Google Ads APIs as per our original blog post. This will affect all versions of both the AdWords API and the Google Ads API. The following behaviors will be blocked:
  • Populating the target spend field on existing standard and portfolio strategies
  • Attaching portfolio strategies that have the deprecated field set to campaigns
Read on to see how this will affect your API usage:
Affected Target Spend Fields
Google Ads API campaign.target_spend.target_spend_micros
bidding_strategy.target_spend.target_spend_micros
AdWords API Campaign.BiddingStrategyConfiguration.TargetSpendBiddingScheme.spendTarget
SharedBiddingStrategy.TargetSpendBiddingScheme.spendTarget

Change Description
Any mutate operations that set a target spend field for the first time will return an error. You will be able to update a target spend field that currently contains a value, but you cannot set previously empty fields to a new value. Additionally, any operation attaching a bidding strategy to a campaign where that bidding strategy has a value set for a target spend field, will throw an error. To manage Target Spend on any new campaigns, we recommend using campaign budget. In each of these cases an error will be thrown.

Performing any of the actions listed above will generate one of the following errors:
  • OPERATION_NOT_PERMITTED_FOR_CONTEXT
  • UNSUPPORTED_FIELD_IS_SET
If you have any questions about this change or any other API feature, please contact us via the forum.
