## Request Parameters

The request accepts the following data in JSON format.

 ** [Filters](#API_ListChangeTypeClassificationSummaries_RequestSyntax) **   <a name="amscm-ListChangeTypeClassificationSummaries-request-Filters"></a>
Attribute/value pairs to narrow the results returned. Filter criteria are combined in a logical OR operation, and values that contain spaces are also combined in an OR operation. For example, a `Value` of "read-only access" matches all values that contain "read-only" OR "access". Valid filter attributes: `Category`, `Subcategory`, `Item`, `Operation`, `ChangeTypeId`.
