+   Un petit mot sur les scopes : tel qu'implémenté, une scope est une permission unitaire

+   a accès à une scope si et seulement si le/la propriétaire du jeton dispose d'une adhésion
+   courante dans le club lié à la scope qui lui octroie cette permission.
+
+   Par exemple, un jeton pourra avoir accès à la permission de créer des transactions en lien
+   avec un club si et seulement si le propriétaire du jeton est trésorier du club.
+
+   La vérification des droits du propriétaire est faite systématiquement, afin de ne pas
+   faire confiance au jeton en cas de droits révoqués à son propriétaire.
+
+   Vous pouvez donc contrôler le plus finement possible les permissions octroyées à vos
+   jetons.
+
+.. danger::
+
+   Demander des scopes n'implique pas de les avoir.
+
+   Lorsque des scopes sont demandées par un client, la Note
+   va considérer l'ensemble des permissions accessibles parmi
+   ce qui est demandé. Dans vos programmes, vous devrez donc
+   vérifier les permissions acquises (communiquées lors de la
+   récupération du jeton d'accès à partir du grant code),
+   et prévoir un comportement dans le cas où des permissions
+   sont manquantes.
+
+   Cela offre un intérêt supérieur par rapport au protocole
+   OAuth2 classique, consistant à demander trop de permissions
+   et agir en conséquence.
+
+   Par exemple, vous pourriez demander la permission d'accéder
+   aux membres d'un club ou de faire des transactions, et agir

+
+Une fois ce code d'autorisation récupéré, il faut désormais récupérer le jeton d'accès.
+Il faut pour cela aller sur l'URL `<https://note.crans.org/o/token/>`_, effectuer une
+requête POST avec pour arguments :
+
+* ``client_id`` ;
+* ``client_secret`` ;
+* ``grant_type`` : mettre ``authorization_code`` ;
+* ``code`` : le code généré.
+
+À noter que le code fourni n'est disponible que pendant quelques secondes.
+
+À des fins de tests, on peut envoyer la requête avec ``curl`` :
+
+.. code:: bash
+
+   curl -X POST https://note.crans.org/o/token/ -d "client_id=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&client_secret=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&grant_type=authorization_code&code=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+
+Le serveur renverra si tout se passe bien une réponse JSON :
+
+.. code:: json
+
+   {
+       "access_token": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
+       "expires_in": 36000,
+       "token_type": "Bearer",
+       "scope": "1_1 1_2",
+       "refresh_token": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+   }
+
+On note donc 2 jetons différents : un d'accès et un de rafraîchissement. Le jeton d'accès
+est celui qui sera donné à l'API pour s'authentifier, et qui expire au bout de quelques
+heures.
+
+Il suffit désormais d'ajouter l'en-tête ``Authorization: Bearer ACCESS_TOKEN`` pour se
+connecter à la note grâce à ce jeton d'accès.
+
+Pour tester :
+
+.. code:: bash
+
+   curl https://note.crans.org/api/me -H "Authorization: Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+
+En cas d'expiration de ce jeton d'accès, il est possible de le renouveler grâce au jeton
+de rafraichissement à usage unique. Il suffit pour cela de refaire une requête sur la page
+`<https://note.crans.org/o/token/>`_ avec pour paramètres :
+
+* ``client_id`` ;
+* ``client_secret`` ;
+* ``grant_type`` : mettre ``refresh_token`` ;
+* ``refresh_token`` : le jeton de rafraîchissement.
+
+Le serveur vous fournira alors une nouvelle paire de jetons, comme précédemment.
+À noter qu'un jeton de rafraîchissement est à usage unique.
+
+N'hésitez pas à vous renseigner sur OAuth2 pour plus d'informations.
