Correct answer - "Using the Header Cache-Control: max-age=0" : A client of your API can invalidate an existing cache entry and reload it from the integration endpoint for individual requests. The client must send a request that contains the Cache-Control: max-age=0 header. The client receives the response directly from the integration endpoint instead of the cache, provided that the client is authorized to do so. This replaces the existing cache entry with the new response, which is fetched from the integration endpoint.

"Use the Request parameter: ?bypass_cache=1" - Method parameters take querystring but this is not one of them

"Using the Header Bypass-Cache=1" - This header is not available

"Using the request parameter ?cache-control-max-age=0" - To invalidate cache it requires a header and not a request parameter
