Hi Buddhimala, Could you please elaborate your use case where you want to implement caching? Since you have the API with CRUD operations, IMO it is not meaningful to cache the responses for PUT and POST. So if you want to cache 200 OK response of GET, you can implement it through a custom sequence using cache mediator in APIM. Please refer [1] for more information.
