list method
Lists custom lists.
The order is defined by the order_by parameter.
Request parameters:
advertiserId - The ID of the DV360 advertiser that has access to the
fetched custom lists.
filter - Allows filtering by custom list fields. Supported syntax: *
Filter expressions for custom lists can only contain at most one
restriction. * A restriction has the form of {field} {operator} {value}.
- All fields must use the 
HAS (:)operator. Supported fields: *displayNameExamples: * All custom lists for which the display name contains "Google":displayName:"Google". The length of this field should be no more than 500 characters. Reference our [filterLISTrequests](/display-video/api/guides/how-tos/filters) guide for more information. 
orderBy - Field by which to sort the list. Acceptable values are: *
customListId (default) * displayName The default sorting order is
ascending. To specify descending order for a field, a suffix "desc" should
be added to the field name. Example: displayName desc.
pageSize - Requested page size. Must be between 1 and 200. If
unspecified will default to 100. Returns error code INVALID_ARGUMENT
if an invalid value is specified.
pageToken - A token identifying a page of results the server should
return. Typically, this is the value of next_page_token returned from the
previous call to ListCustomLists method. If not specified, the first
page of results will be returned.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListCustomListsResponse.
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.
