You can put anything in that. For instance, www.google.com, www.facebook.com etc.
You will not need that redirect url in python code because there are already pre generated functions to get "feed token". 👇🏻
feedToken=obj.getfeedToken()
But you don't have to think for all this stuff because there is ready made code to get live share prices, just put your client ID, password and API key in that code and have fun.
