title: How to prevent autheticated user from sending similar request via POSTMAN?
body: <p>I am developing a simple website using MEAN stack that gives a logged-in user a task to complete and sends a score to the backend corresponding to their performance on that task. User can skip to next task in which case no score is sent. Problem is: How can I differentiate between a user cheating and sending score via a POST request on POSTMAN (by changing POST values to increase score) and a POST request created by my frontend code. How to work around this problem?</p>
