Migrating AdWords Services to Google Ads Services

The Google Ads API shares most of the same functionality as the AdWords API, however a small number of services have changed. Some have been deprecated, some have been split into multiple new services, and some have been consolidated into a single new service.

To help in your migration to the Google Ads API, below is a comprehensive list of all of the AdWords services and their Google Ads API equivalent.

Mapping AdWords API Services to Google Ads API Services
AccountLabelService LabelService

Account-level labels are now just referred to as Labels.

ConstantDataService GoogleAdsService

The mapping from ConstantDataService method return type to Google Ads API type is as follows:

  • getAgeRangeCriterion -> AgeRangeTypeEnum
  • getCarrierCriterion -> CarrierConstant
  • getGenderCriterion -> GenderTypeEnum
  • getLanguageCriterion -> LanguageConstant
  • getMobileAppCategoryCriterion -> MobileAppCategoryConstant
  • getMobileDeviceCriterion -> MobileDeviceConstant
  • getOperatingSystemVersionCriterion -> OperatingSystemVersionConstant
  • getProductBiddingCategoryData -> ProductBiddingCategoryConstant
  • getUserInterestCriterion -> UserInterest
  • getVerticalCriterion -> TopicConstant

Use GoogleAdsService.search to retrieve any of these resources, with the exception of age ranges and genders, which are now represented as AgeRangeTypeEnum and GenderTypeEnum, respectively.

ConversionTrackerService ConversionActionService
RemarketingActionService

In the AdWords API, both conversion actions and remarketing actions were available via the ConversionTrackerService, with remarketing actions represented as immutable AdWordsConversionTracker objects with status=HIDDEN and category=REMARKETING.

In the Google Ads API, remarketing actions are a separate resource type that's managed via the RemarketingActionService.

To get custom interest data query the custom_interest resource using Search.

LabelService AdGroupAdLabelService
AdGroupCriterionLabelService
AdGroupLabelService
CampaignLabelService
CustomerLabelService

Retrieving Labels is done through the LabelService, however mutations are done via entirely new services instead of methods on resource-specific services. For example, In the AdWords API, mutating a campaign label was done with the CampaignService.mutatelabel method, but in the Google Ads API it's done with the CampaignLabelService. All of the #mutatelabel methods have been moved to new services as follows:

  • AdGroupAdService#mutatelabel -> AdGroupAdLabelService
  • AdGroupCriterionService#mutatelabel -> AdGroupCriterionLabelService
  • AdGroupService#mutatelabel -> AdGroupLabelService
  • CampaignService#mutatelabel -> CampaignLabelService
  • ManagedCustomerService#mutatelabel -> CustomerLabelService

Note that to mutate Account Labels you should use the LabelService in Google Ads.
