Resource names used in the Google Ads API are hierarchical, mirroring the
organization of entities within Google Ads. Almost all resources are sub-resources
resource, which reflects the fact that almost every API call has to target a
specific Google Ads account. For example, campaigns, ad groups, ads, and keywords
are all sub-resources of a root customer resource.
Google Ads entities (customers, campaigns, etc.) are referred to by their resource names throughout the API. However, it’s important to note that the resource names themselves may have unique numerical resource IDs that identify each object in the hierarchy. In these cases, it may be useful to parse the resource name to extract these resource IDs and assemble a new one.
For example, examine the AdGroupAd resource name from the previous table:
This can be broken down into its individual resource IDs (separated by collection IDs) as follows:
|Resource name components|
Parsing the individual IDs allows you to derive new resource names to reference
the ad group ad's customer (
customers/1234567890) or its ad group
