@ImranAhmed If I am understanding you correctly, you are trying to verify the content has correctly been modified before it is written out via your invokeHTTP processor.Inspecting that your dataflow is working as expected.  If you stop your InvokeHTTP processor after the ReplaceText processor, the FlowFile processed by the ReplaceText will queue in the connection.  You can then right click on the connection and list the queue.  From there you can view/download the content of that FlowFile post ReplaceText to verify it contains the expected modified content before the InvokeHTTP is started and writes it to your DB.   Thanks, Matt ...
