-- Returns a list of cases that you specify by passing one or more case
-- IDs. You can use the @afterTime@ and @beforeTime@ parameters to filter
-- the cases by date. You can set values for the @includeResolvedCases@ and
-- @includeCommunications@ parameters to specify how much information to
-- return.
--
-- The response returns the following in JSON format:
--
-- -   One or more
--     <https://docs.aws.amazon.com/awssupport/latest/APIReference/API_CaseDetails.html CaseDetails>
--     data types.
--
-- -   One or more @nextToken@ values, which specify where to paginate the
--     returned records represented by the @CaseDetails@ objects.
--
-- Case data is available for 12 months after creation. If a case was
-- created more than 12 months ago, a request might return an error.
--
-- -   You must have a Business, Enterprise On-Ramp, or Enterprise Support
--     plan to use the Amazon Web Services Support API.
--
-- -   If you call the Amazon Web Services Support API from an account that
--     doesn\'t have a Business, Enterprise On-Ramp, or Enterprise Support
--     plan, the @SubscriptionRequiredException@ error message appears. For
--     information about changing your support plan, see
--     <http://aws.amazon.com/premiumsupport/ Amazon Web Services Support>.
--
-- This operation returns paginated results.
