requestParameters

A key-value map defining required or optional method request parameters that can be accepted by API Gateway. A key is a method request parameter name matching the pattern of `method.request.{location}.{name}`, where `location` is `querystring`, `path`, or `header` and `name` is a valid and unique parameter name. The value associated with the key is a Boolean flag indicating whether the parameter is required (`true`) or optional (`false`). The method request parameter names defined here are available in Integration to be mapped to integration request parameters or templates.
