public java.util.Map<String, Boolean> getResponseParameters() {
        return responseParameters;
    }
<p>
A key-value map specifying required or optional response parameters that API Gateway can send back to the caller.
A key defines a method response header and the value specifies whether the associated method response header is
required or not. The expression of the key must match the pattern <code>method.response.header.{name}</code>,
where <code>name</code> is a valid and unique header name. API Gateway passes certain integration response data
to the method response headers specified here according to the mapping you prescribe in the API's
IntegrationResponse. The integration response data that can be mapped include an integration response header
expressed in <code>integration.response.header.{name}</code>, a static value enclosed within a pair of single
quotes (e.g., <code>'application/json'</code>), or a JSON expression from the back-end response payload in the
form of <code>integration.response.body.{JSON-expression}</code>, where <code>JSON-expression</code> is a valid
JSON expression without the <code>$</code> prefix.)
