Google Ads API 中實體的專屬 ID 稱為「資源名稱」，以可預測格式的字串表示。如果您知道資源名稱的組成元件，可以使用許多服務物件上的輔助方法產生資源名稱。
服務路徑方法
所有用於處理 API 中特定類型物件讀取或變動的服務，都有建構資源名稱的輔助方法。舉例來說，您可以為 Campaign 物件建立資源名稱：
from google.ads.googleads.client import GoogleAdsClient
client = GoogleAdsClient.load_from_storage()
customer_id = "7892134783"
campaign_id = "1234567890"
campaign_service = client.get_service("CampaignService")
resource_name = campaign_service.campaign_path(customer_id, campaign_id)
每項服務也有隨附的 parse_*_path 方法，可將資源名稱解構為個別區隔的字典 (如果字串不符合預期格式，則會傳回空白字典)：
from google.ads.googleads.client import GoogleAdsClient
client = GoogleAdsClient.load_from_storage()
resource_name = "customers/7892134783/campaigns/1234567890"
campaign_service = client.get_service("CampaignService")
segments = campaign_service.parse_campaign_path(resource_name)
customer_id = segments["customer_id"]
campaign_id = segments["campaign_id"]
複合資源名稱
服務上的路徑輔助程式會建構資源名稱的複合區隔。複合 ID 的不同區段會以個別參數的形式傳遞至方法：
from google.ads.googleads.client import GoogleAdsClient
customer_id = "0987654321"
ad_group_id = "1234567890"
criterion_id = "74932"
client = GoogleAdsClient.load_from_storage()
ad_group_criterion_service = client.get_service("AdGroupCriterionService")
# An AdGroupCriterion resource name that uses these IDs looks like this:
# "customers/0987654321/adGroupCriteria/1234567890~74932"
resource_name = ad_group_criterion_service.ad_group_criterion_path(
customer_id, ad_group_id, criterion_id
)
