oauth2 redirect_uri and web server..

[9acca9]

Hello.
Im trying to make a cellphone app for the great web lichess.org.

I read the documentation of the lichess API and also the documentation for the python module related.

https://lichess.org/api#tag/OAuth/operation/oauth

https://lichess-org.github.io/berserk/usage.html#authenticating (here there is no much info about oauth2.)

Except:

you can use requests_oauthlib.Oauth2Session for this.
from requests_oauthlib import OAuth2Session
session = OAuth2Session(...)
client = berserk.Client(session)

In the lichess API you will read:
redirect_uri required.... The absolute URL that the user should be redirected to with the authorization result.

And they recommend, as i understand to use oauth2

Login with Lichess, without a web server backend
Authenticate your users with a simple "Login with Lichess" button, if you don't have a webserver. Perfectly suited to mobile apps, CLI apps, client-side JS apps.

This allows you to make requests to Lichess on behalf of your app users. It is safe, and scales very well with many users.
Relevant code example: [oauth-app](https://github.com/lichess-org/api/tree/master/example/oauth-app)

Well, lets say that i have two problems for now:
What will be the redirect_uri in the cellphone app???? i dont get it.
And... i need to put a web server up to debug the app?

Thank you all.

Well, it seems that i have to use a "custom uri"

somebody have experience with that in kivy??? or a "reverse domain name pattern"......
