While Mutate, Search, and SearchStream are the most common methods
in the Google Ads API, there are many others for specific purposes. All services and
their APIs are documented in the
reference documentation.
For example, the customer_service.proto file
defines a ListAccessibleCustomers method, in addition to the standard Mutate
. Its google.api.http annotation describes
how the method maps to HTTP. It uses an HTTP GET with the custom verb
listAccessibleCustomers:
Another example from customer_service.proto is
the CreateCustomerClient method. Its google.api.http annotation describes an
HTTP POST using the custom verb createCustomerClient:
