@AnnapurnaGautam You need to set EvaluateJson to flowfile-attribute. Then you can use attribute ${id} in InvokeHTTP Remote Url. You only use flowfile-content when you need the values in the body (flow file) for invokeHttp.

Please see my response in Cloudera Community with a template and the syntax for evaluateJsonPath to get ${id}.

$.history[0].id
