+Le site AE offre des mécanismes permettant aux applications tierces
+de récupérer les informations sur un utilisateur du site AE.
+De cette manière, il devient possible de synchroniser les informations
+qu possède l'application tierce sur l'utilisateur, directement depuis
+le site AE.
+
+## Fonctionnement général
+
+Pour authentifier vos utilisateurs, vous aurez besoin d'un serveur web
+et d'un client d'API (celui auquel est liée votre
+[clef d'API](./connect.md#obtenir-une-clef-dapi)).
+Deux informations vous sont nécessaires, en plus de votre clef d'API :
+
+- l'id du client : vous pouvez l'obtenir soit en le demandant à l'équipe info,
+  soit en appelant la route `GET /client/me` avec votre clef d'API
+  renseignée dans le header [X-APIKey](./connect.md#x-apikey)
+- la clef HMAC du client : vous devez la demander à l'équipe info.
+
+Grâce à ces informations, vous allez pouvoir fournir le contexte nécessaire
+au site AE pour qu'il authentifie vos utilisateurs.
+
+En effet, la démarche d'authentification s'effectue presque entièrement
+sur le site : le travail de l'application tierce consiste uniquement
+à fournir à l'utilisateur une url avec les bons paramètres, puis
+à recevoir la réponse du serveur si tout s'est bien passé.
+
+Comme un dessin vaut parfois mieux que mille mots,
+voici les diagrammes décrivant le processus.
+L'un montre l'entièreté de la démarche ;
+l'autre dans un souci de simplicité, ne montre que ce qui est visible
+directement par l'application tierce.
+
+=== "Intégralité du processus"
+

+        end
+    ```
+
+## Données attendues
+
+### URL de connexion
+
+L'URL de connexion que vous allez fournir à l'utilisateur doit
+être `https://ae.utbm.fr/api-link/auth/`
+et doit contenir les données décrites dans
+[`ThirdPartyAuthParamsSchema`][api.schemas.ThirdPartyAuthParamsSchema] :
+
+- `client_id` (integer) : l'id de votre client, que vous pouvez obtenir
+  de la manière décrite plus haut
+- `third_party_app`(string) : le nom de la plateforme pour laquelle
+  l'authentification va être réalisée (si votre application est un bot
+  discord, mettez la valeur "discord")
+- `privacy_link`(URL) : l'URL vers la page de politique de confidentialité
+  qui s'appliquera dans le cadre de l'application
+  (s'il s'agit d'un bot discord, donnez le lien vers celles de Discord)
+- `username`(string) : le pseudonyme que l'utilisateur possède sur
+  votre application
+- `callback_url`(URL) : l'URL que le site AE appellera si l'authentification
+  réussit
+- `signature`(string) : la signature des données de la requête.
+
+Ces données doivent être url-encodées et passées dans les paramètres GET.
+
+!!!tip "URL de retour"
+
+    Notre système n'impose aucune contrainte quant à la manière
+    de construire votre URL (hormis le fait que ce doit être une URL HTTPS valide),
+    mais il est tout de même conseillé d'utiliser l'identifiant de votre
+    utilisateur comme paramètre dans l'URL 
+    (par exemple `GET /callback/{int:user_id}/`).
+
+???Example
+
+    Supposons que votre client d'API soit utilisé dans le cadre d'un bot Discord,
+    avec les données suivantes :
+    
+    - l'id du client est 15
+    - sa clef HMAC est "beb99dd53"
+      (c'est pour l'exemple, une vraie clef sera beaucoup plus longue)
+    - le pseudonyme discord de votre utilisateur est Brian
+    - son id sur discord est 123456789
+    - votre route de callback est `GET /callback/{int:user_id}/`,
+      accessible au domaine `https://bot.ae.utbm.fr`
+    
+    Alors les paramètres de votre URL seront :
+    
+    | Paramètre       | valeur                                                                |

+    | privacy_link    | `https://discord.com/privacy`                                         |

+
+### Données de retour
+
+Si l'authentification réussit, le site AE enverra une requête HTTP POST
+à l'URL de retour fournie dans l'URL de connexion.
+
+Le corps de la requête de callback et au format JSON 
+et contient deux paires clef-valeur :
+
+- `user` : les données utilisateur, telles que décrites
+  par [UserProfileSchema][core.schemas.UserProfileSchema]
+- `signature` : la signature des données utilisateur
+
+???Example
+
+    En reprenant les mêmes paramètres que dans l'exemple précédent,
+    le site AE pourra renvoyer à l'application la requête suivante :
+
+    ```http
+    POST https://bot.ae.utbm.fr/callback/123456789/
+    content-type: application/json
+    body: {
+        "user": {
+            "id": 144131,
+            "nick_name": "inzekitchen",
+            "first_name": "Brian",
+            ...
+        },
+        "signature": "f16955bab6b805f6e1abbb98a86dfee53fed0bf812aa6513ca46cfd461b70020"
+    }
+    ```
+
+L'application doit répondre avec un des codes HTTP suivants :
+
+| Code | Raison                                                                         |
+|------|--------------------------------------------------------------------------------|
+| 204  | Tout s'est bien passé                                                          |
+| 403  | Les données de retour ne sont <br>pas signées ou sont mal signées              |
+| 404  | L'URL de retour ne permet pas <br>d'identifier un utilisateur de l'application |
+
+!!!note "Code d'erreur par défaut"
+
+    Si l'appel de la route fait face à plusieurs problèmes en même temps 
+    (par exemple, l'URL ne permet pas de retrouver votre utilisateur, 
+    et en plus les données sont mal signées),
+    le 403 prime et doit être retourné par défaut.
+
+## Signature des données
+
+Les données de l'URL de connexion doivent être signées,
+et la signature de l'URL de retour doit être vérifiée.
+
+Dans le deux cas, la signature est le digest HMAC-SHA512
+des données url-encodées, en utilisant la clef HMAC du client d'API.
+
+???Example "Signature de l'URL de connexion"
+
+    En reprenant le même exemple que les fois précédentes,
+    l'url-encodage des données est :
+
+    `client_id=15&third_party_app=discord
+    &privacy_link=https%3A%2F%2Fdiscord.com%2Fprivacy%2F&username=Brian
+    &callback_url=https%3A%2F%2Fbot.ae.utbm.fr%2Fcallback%2F123456789%2F`
+
+    Notez que la signature n'est pas (encore) dedans.
+    Cette dernière peut-être obtenue avec le code suivant :

+            is_signature_valid(post_data["user"], post_data["signature"]
+        )
+    ```
+
+!!!Warning
+
+    Vous devez impérativement vérifier la signature 
+    des données de la requête de callback !
+
+    Si l'équipe informatique se rend compte que vous ne le faites pas,
+    elle se réserve le droit de suspendre votre application,
+    immédiatement et sans préavis.
