BOX API authentication get auth_code

Question

I am trying to interact with the BOX API. I did multiple researches and I followed multiple tutorials on how to do it but I am missing a step... I need to get the auth_code in order to get the refresh_token and the access_token. From what I understood the auth_code comes as a parameter in the url after the authentication.

from boxsdk import OAuth2
SDK = OAuth2(
    client_id=CLIENTID,
    client_secret=CLIENTSECRET
)
auth_url, csrf_token = SDK.get_authorization_url('{}/api/oauth2/authorize?response_type=code&client_id={}&redirect_uri={}/folder/0'.format(ENPOINT, CLIENTID, ENPOINT))
TOKENS['auth_url'] = auth_url
TOKENS['csrf_token'] = csrf_token
requests.get(auth_url)

When I access by browser the url returned in auth_url it takes me to site like this: .

And after I click manually in Grant access to Box it redirects me to the Box folder of my choice and the url is in the format: https://xxxxx.com/folder/0?code=zzzzz&state=yyyyy. My goal is to extract the zzzzz and I do not understand how to get it programmatically...

A little help would be of great value, thanks in advance

Partial Answer: You retrieve the code by doing the following. Just redirect:

auth_url, csrf_token = oauth.get_authorization_url('https://google.com')

You have to set your Redirect URIs in the dev console to https://google.com. In the URL that you get back is the code that you need.

Remaining Issue: The only problem is that you have to grant access manually. I still have to overcome that problem. Then would the problem be solved. Anyone have an idea how to grant access?
