Can I use the Discourse API to authenticate users in another app?

SSO
12

Here are 20 lines of Python code that do approximately the same as the React Native code referred to by @renato (except no compatibiliy with Discourse 2.5 - I don’t need that)

It works well, assuming that you are using basic username-password based login. I will still look into the alternative methods, using the Discourse SSO login as configured in the Discourse instance.

import requests
import json

def discourse_authenticate(url, name, password):
    session = requests.Session()
    session.headers.update({'X-Requested-With': 'XMLHttpRequest'})
    r1 = session.get(url + '/session/csrf')
    csrf_token = json.loads(r1.text).get('csrf')
    r2 = session.post(url + '/session',
        data={
            'login': name,
            'password': password,
            'authenticity_token': csrf_token,
        },
    )
    if r2.status_code != 200:
        return None
    return json.loads(r2.text)
