As expected with any REST implementation, the Google Ads API does have a get
method for each resource, and is invoked as a standard HTTP GET using a
resource name in its URL. The method returns a full resource with all of its
fields populated.
For example, to get an individual campaign, send a standard HTTP GET using the
campaign's resource name, and include the resource IDs for the customer ID and
campaign ID:
GET /v5/customers/CUSTOMER_ID/campaigns/CAMPAIGN_ID HTTP/1.1 Host: googleads.googleapis.com Authorization: Bearer ACCESS_TOKEN developer-token: DEVELOPER_TOKEN
Because the get method only returns a single object per response, and that
object has all fields fully populated (as opposed to returning just the fields
you're interested in), it is intended only for debugging and testing. For
production code, always use the search or searchStream methods.
