Vous pouvez passer des paramètres propres au fournisseur à un fournisseur d’identité (<Tooltip href="/docs/fr-ca/glossary?term=idp" tip="Fournisseur d’identité (IdP)
Service de stockage et de gestion des identités numériques." cta="Voir le glossaire">IdP</Tooltip>) lors de l’authentification. Les valeurs peuvent être statiques par connexion ou dynamiques par utilisateur.

## Limites

Pour cette configuration, il faut tenir compte des restrictions suivantes :

* Seuls les [paramètres Oauth 2.0/OIDC valides](http://openid.net/specs/openid-connect-core-1_0.html#AuthorizationEndpoint) sont acceptés.
* Tous les IdPs ne prennent pas en charge les paramètres en amont. Vérifiez auprès du fournisseur d’identité (IdP) concerné avant de procéder à votre mise en œuvre.
* Les fournisseur d’identité (IdP) <Tooltip href="/docs/fr-ca/glossary?term=security-assertion-markup-language" tip="Security Assertion Markup Language (SAML)
  Protocole normalisé permettant à deux parties d’échanger des informations d’authentification sans mot de passe." cta="Voir le glossaire">SAML</Tooltip> ne prennent pas en charge les paramètres en amont.

## Paramètres statiques

Utilisez les paramètres statiques pour configurer votre connexion afin d’envoyer un ensemble standard de paramètres à l’IdP lorsqu’un utilisateur se connecte.

Pour configurer les paramètres statiques, appelez le point de terminaison d’Auth0 Management API [Créer une connexion](https://auth0.com/docs/api/management/v2/#!/Connections/post_connections) ou [Mettre à jour une connexion](https://auth0.com/docs/api/management/v2/#!/Connections/patch_connections_by_id) et passez l’objet `upstream_params` dans l’objet `options` avec les paramètres que vous souhaitez envoyer à l’IdP.

### Exemple : WordPress

WordPress vous permet de passer un paramètre `blog` facultatif à son point de terminaison d’autorisation <Tooltip href="/docs/fr-ca/glossary?term=oath2" tip="OAuth 2.0
Cadre d’applications d’autorisation qui définit les protocoles d’autorisation et les flux de production." cta="Voir le glossaire">OAuth</Tooltip> 2.0, et de demander automatiquement l’accès à un blog précis pour les utilisateurs lorsqu’ils se connectent. Pour en savoir plus, veuillez consulter la [documentation Oauth 2.0 de WordPress](https://developer.wordpress.com/docs/oauth2/).

Pour suivre cet exemple, vous aurez besoin d’une [connexion WordPress via réseau social](https://marketplace.auth0.com/integrations/wordpress-social-connection).

#### Obtenir la connexion

L’objet `options` ressemblera à ceci :

```json lines theme={null}

    "profile": true, 
    "scope": ["profile"]
  }
}
```

#### Mettre à jour la connexion (statique)

Copier l’objet `options` existant, puis ajouter l’objet `upstream_params` avec le champ `blog` comme attribut :

```json lines theme={null}
{
  "options": {
    "client_id": "", 
    "profile": true, 
    "scope": ["profile"],
    "upstream_params": {

Désormais, chaque fois qu’un utilisateur s’authentifie avec cette connexion, la demande au point de terminaison d’autorisation de Wordpress inclura le paramètre de requête `blog=myblog.wordpress.com`.

## Paramètres dynamiques

Utilisez les paramètres dynamiques pour configurer votre connexion afin qu’un ensemble de paramètres ayant des valeurs propres à l’utilisateur soit envoyé au fournisseur d’identité (IdP) au moment où il se connecte.

Pour configurer les paramètres dynamiques, appelez le point de terminaison d’Auth0 Management API [Créer une connexion](https://auth0.com/docs/api/management/v2/#!/Connections/post_connections) ou [Mettre à jour une connexion](https://auth0.com/docs/api/management/v2/#!/Connections/patch_connections_by_id), passez l’objet `upstream_params` dans l’objet `options` avec les paramètres que vous souhaitez envoyer à l’IdP et précisez le champ auquel le paramètre correspond avec l’attribut `alias`.

Voici un exemple d’objet `options` que nous revisiterons plus tard dans l’exemple X :

```json lines theme={null}
{
  "options": {
    "upstream_params": {
      "screen_name": {
        "alias": "login_hint"
      }
    }
  }
}
```

### Champs disponibles

Voici les champs disponibles pour l’attribut `alias` :

* `acr_values`
* `audience`
* `client_id`
* `display`
* `id_token_hint`
* `login_hint`
* `max_age`
* `prompt`
* `resource`
* `response_mode`
* `response_type`
* `ui_locales`

### Exemple : X

X vous permet de passer un paramètre optionnel `screen_name` à son point de terminaison d’autorisation OAuth. Le paramètre `screen_name` préremplit la zone de saisie du nom d’utilisateur à l’écran de connexion avec la valeur donnée. Pour en savoir plus, veuillez consulter la [Référence de l’API de X](https://developer.twitter.com/en/docs/basics/authentication/api-reference/authorize).

Pour suivre cet exemple, vous aurez besoin d’une [Connexion via réseau socialTwitter](https://marketplace.auth0.com/integrations/twitter-social-connection) opérationnelle.

#### Appeler le point de terminaison de connexion

Lorsque vous appelez le [point de terminaison de connexion](https://auth0.com/docs/api/authentication#login) de l’Authentication API pour un utilisateur, vous pouvez transmettre son adresse courriel au paramètre `login_hint` :

export const codeExample41 = `https://{yourDomain}/authorize
  ?client_id={yourClientId}
  &response_type=token
  &redirect_uri={https://yourApp/callback}
  &scope=openid%20name%20email
  &login_hint=user@domain.com`;

<AuthCodeBlock children={codeExample41} language="text" lines />

Cette valeur sera ensuite transmise au point de terminaison d’autorisation X sous forme de paramètre `screen_name` :
