Optional. A filter constraining the accounts to return. The response includes only entries that match the filter. If filter is empty, then no constraints are applied and all accounts (paginated) are retrieved for the requested account. For example, a request with the filter type=USER_GROUP will only return user groups. The type field is the only supported filter.

Optional. How many accounts to fetch per page. The default and maximum is 20.

Optional. If specified, the next page of accounts is retrieved. The pageToken is returned when a call to accounts.list returns more results than can fit into the requested page size.

Optional. The resource name of the account for which the list of directly accessible accounts is to be retrieved. This only makes sense for Organizations and User Groups. If empty, will return ListAccounts for the authenticated user. accounts/{account_id}.
