Is there an http address that allows you to exit the window?

I am trying to authenticate using OAuth

First of all, you can log in if you write down the address by displaying the Chrome custom tab on Android.

Parse response is then delivered to the address you set.

I think it's a method of taking the delivered value and cutting only the access token and making a request...

It's been a while since I got the price manually

When you create an application, you must log in from the user by displaying this custom tab.

But when I'm done logging in like that, I don't have to open a window, I just need to get an access token.

The place that provides the API requires a callback url. What should I do?
