OAuth 2.0 Capture Redirect

Hello,

I am currently trying to implement OAuth 2.0 into my Windows application to access a t$$anonymous$$rd party API. It requires me to open a Webpage for the user to login and then redirects to a custom URL with the access token in it.

I first tried to get it wokring over UnityWebRequest, but that does not seem to work when the user has to manually enter $$anonymous$$s/her login details on the t$$anonymous$$rd party website before the redirect (or at least it never opened the browser in my initial tests).

So my current plan would be to have that redirect URL beeing a local php script that stores the access token in a seperate file, w$$anonymous$$ch I could then read in Unity again. Unfortunately, my php skills are not existent, so I was wondering whether someone could help me out :)
