# InterfaceFilter1
## Properties
**interface_id** | Option<**String**> | The interface that a matching contract must implement. The ``interface_id`` needs to be valid: corresponding interface should be defined in one of the available packages at the time of the query. Both package-name and package-id reference formats for the identifier are supported. Note: The package-id reference identifier format is deprecated. We plan to end support for this format in version 3.4. Required | [optional]
**include_interface_view** | **bool** | Whether to include the interface view on the contract in the returned ``CreatedEvent``. Use this to access contract data in a uniform manner in your API client. Optional |
**include_created_event_blob** | **bool** | Whether to include a ``created_event_blob`` in the returned ``CreatedEvent``. Use this to access the contract create event payload in your API client for submitting it as a disclosed contract with future commands. Optional |
