Send the cookie with the JSON request

While logged into a secure website with a login, I came across some valuable data that is transmitted through the server in JSON format. By opening Chrome and inspecting the page using the "Network" tab, I discovered a URL utilizing XHR which contained the JSON data I was seeking. However, upon attempting to access the same URL in a separate tab, I received an error message:

{"statusCode":400,"error":"Bad Request","message":"Invalid cookie value"}

Although I am able to view the data in the inspect tool, loading the exact URL directly in the browser resulted in an error due to a missing cookie required for validation by the server. Is there a way to bypass this issue or somehow transfer the necessary session cookie to the server in order to obtain the raw JSON response via a URL?

My main objective is to parse the JSON data with Tampermonkey.

Answer №1

Setting cookies in browser requests can be tricky for users, especially when trying to do it through the address bar. However, there are numerous tools available that can help with this task. Personally, I rely on Postman for sending requests, along with their tool Interceptor which allows me to easily set cookies.
