list method
Lists all the known client users for a specified sponsor buyer account ID.
Request parameters:
accountId - Numerical account ID of the sponsor buyer of the client to
list users for. (required)
clientAccountId - The account ID of the client buyer to list users for.
(required) You must specify either a string representation of a numerical
account identifier or the - character to list all the client users for
all the clients of a given sponsor buyer.
pageSize - Requested page size. The server may return fewer clients than
requested. If unspecified, the server will pick an appropriate default.
pageToken - A token identifying a page of results the server should
return. Typically, this is the value of
ListClientUsersResponse.nextPageToken returned from the previous call to
the accounts.clients.users.list method.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListClientUsersResponse.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
