Open your Firefox browser and go to http://localhost/vapi. Then, navigate to API No 6. Now, let's explore the functionality of this API by sending a POST request to create a user. We have successfully created a user. Now, let's send a GET request to the API endpoint to see what we get in return. The following parameters are returned: id, name, username, and a new parameter called "credit" with a value of 0. I am interested in tampering with the value of the "credit" parameter.
