Making request to an ASP.NET WebForm problem

I am currently trying to retrieve data from another site and when submitting the form its __VIEWSTATE
form data key is causing errors as it changes each submission based on the data in the form

How can I get the __VIEWSTATE value in my node.js server so the request doesn’t error?

To be honest with you, I honestly know nothing about ASP.NET/C#. This is what I found by doing some searches:


Maybe you just need to decryption the contents of this __VIEWSTATE?
And just wondering, are you trying to get data from roblox? They use ASP.NET for their website, right?

Idk what roblox uses, I’m getting data from my schools website they use to store grades
