OptionalassetWhen retrieving extensions with a query; frequently the caller only needs a small subset of the assets. The caller may specify a list of asset types that should be returned if the extension contains it. All other assets will not be returned.
OptionalfiltersEach filter is a unique query and will have matching set of extensions returned from the request. Each result will have the same index in the resulting array that the filter had in the incoming query.
OptionalflagsThe Flags are used to determine which set of information the caller would like returned for the matched extensions.
An ExtensionQuery is used to search the gallery for a set of extensions that match one of many filter values.
