list method
Lists the transfers for a customer by source user, destination user, or status.
Request parameters:
customerId - Immutable ID of the Google Workspace account.
maxResults - Maximum number of results to return. Default is 100.
Value must be between "1" and "500".
newOwnerUserId - Destination user's profile ID.
oldOwnerUserId - Source user's profile ID.
pageToken - Token to specify the next page in the list.
status - Status of the transfer.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a DataTransfersListResponse.
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.
