@Vamshi245  Yes,  HandleHttpRequest and HandleHttpResponse are used in tandem.  Behind the processors is a map cache which holds connection session between request/response processors.   If your flowfile (json) coming out of custom HandleHttpRequest is delivered to stock HandleHttpResponse, it will send the json to the original connecting client.   If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.
