// Represents a client-facing interface by which the client calls the API to
// access back-end resources. A Method resource is integrated with an Integration
// resource. Both consist of a request and one or more responses. The method
// request takes the client input that is passed to the back end through the
// integration request. A method response returns the output from the back end to
// the client through an integration response. A method request is embodied in a
// Method resource, whereas an integration request is embodied in an Integration
// resource. On the other hand, a method response is represented by a
// MethodResponse resource, whereas an integration response is represented by an
// IntegrationResponse resource.
