  ### Mettre à jour les métadonnées utilisateur
</div>

Vous pouvez mettre à jour les métadonnées d’un utilisateur en effectuant un appel `PATCH` vers le endpoint [`/patch_users_by_id`](https://auth0.com/docs/api/management/v2#!/Users/patch_users_by_id) de la Management API.

Supposons que vous ayez créé un utilisateur avec les valeurs de métadonnées suivantes :

```json lines theme={null}
{
    "email": "jane.doe@example.com",
    "user_metadata": {
        "hobby": "surfing"
    },
    "app_metadata": {
        "plan": "full"
    }
}
```

Pour mettre à jour `user_metadata` et ajouter l’adresse résidentielle de l’utilisateur comme propriété de second niveau :

```json lines theme={null}
{
    "addresses": {
        "home": "123 Main Street, Anytown, ST 12345"
    }
}
```

Vous feriez la requête `PATCH` suivante :

<AuthCodeGroup>
  ```bash cURL theme={null}
  curl --request PATCH \
    --url 'https://{yourDomain}/api/v2/users/user_id' \
    --header 'authorization: Bearer MGMT_API_ACCESS_TOKEN' \
    --header 'content-type: application/json' \
    --data '{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345"}}}'
  ```

  ```csharp C# theme={null}
  var client = new RestClient("https://{yourDomain}/api/v2/users/user_id");
  var request = new RestRequest(Method.PATCH);
  request.AddHeader("authorization", "Bearer MGMT_API_ACCESS_TOKEN");
  request.AddHeader("content-type", "application/json");
  request.AddParameter("application/json", "{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345"}}}", ParameterType.RequestBody);
  IRestResponse response = client.Execute(request);
  ```

  ```go Go theme={null}
  package main

  import (
  	"fmt"
  	"strings"
  	"net/http"
  	"io/ioutil"
  )

  func main() {

  	url := "https://{yourDomain}/api/v2/users/user_id"

  	payload := strings.NewReader("{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345"}}}")

  	req, _ := http.NewRequest("PATCH", url, payload)

  	req.Header.Add("authorization", "Bearer MGMT_API_ACCESS_TOKEN")
  	req.Header.Add("content-type", "application/json")

  	res, _ := http.DefaultClient.Do(req)

  	defer res.Body.Close()
  	body, _ := ioutil.ReadAll(res.Body)

  	fmt.Println(res)
  	fmt.Println(string(body))

  }
  ```

  ```java Java theme={null}

    .header("authorization", "Bearer MGMT_API_ACCESS_TOKEN")
    .header("content-type", "application/json")
    .body("{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345"}}}")
    .asString();
  ```

  ```javascript Node.JS theme={null}
  var axios = require("axios").default;

  var options = {
    method: 'PATCH',
    url: 'https://{yourDomain}/api/v2/users/user_id',

      authorization: 'Bearer MGMT_API_ACCESS_TOKEN',
      'content-type': 'application/json'
    },
    data: {user_metadata: {addresses: {home: '123 Main Street, Anytown, ST 12345'}}}
  };

  axios.request(options).then(function (response) {
    console.log(response.data);
  }).catch(function (error) {
    console.error(error);
  });
  ```

  ```php PHP theme={null}
  $curl = curl_init();

  curl_setopt_array($curl, [
    CURLOPT_URL => "https://{yourDomain}/api/v2/users/user_id",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,

    ],
  ]);

  $response = curl_exec($curl);
  $err = curl_error($curl);

  curl_close($curl);

  if ($err) {
    echo "cURL Error #:" . $err;
  } else {
    echo $response;
  }
  ```

  ```python Python theme={null}
  import http.client

  conn = http.client.HTTPSConnection("")

  payload = "{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345"}}}"

  headers = {
      'authorization': "Bearer MGMT_API_ACCESS_TOKEN",
      'content-type': "application/json"
      }

  conn.request("PATCH", "/{yourDomain}/api/v2/users/user_id", payload, headers)

  res = conn.getresponse()
  data = res.read()

  print(data.decode("utf-8"))
  ```

  ```ruby Ruby theme={null}
  require 'uri'
  require 'net/http'
  require 'openssl'

  url = URI("https://{yourDomain}/api/v2/users/user_id")

  http = Net::HTTP.new(url.host, url.port)
  http.use_ssl = true
  http.verify_mode = OpenSSL::SSL::VERIFY_NONE

  request = Net::HTTP::Patch.new(url)
  request["authorization"] = 'Bearer MGMT_API_ACCESS_TOKEN'
  request["content-type"] = 'application/json'
  request.body = "{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345"}}}"

  response = http.request(request)
  puts response.read_body
  ```
</AuthCodeGroup>

Le profil de l’utilisateur se présentera désormais comme suit :

```json lines theme={null}
{
    "email": "jane.doe@example.com",
    "user_metadata": {
        "hobby": "surfing",
        "addresses": {
            "home": "123 Main Street, Anytown, ST 12345"
        }
    },
    "app_metadata": {
        "plan": "full"
    }
}
```

<Warning>
  Lorsque vous envoyez un appel `PATCH` dans lequel vous définissez la valeur d'une propriété à `null` (par exemple, `{user_metadata: {color: null}}`), Auth0 **supprime** la paire propriété/valeur de la base de données. De plus, si vous appliquez un `PATCH` aux métadonnées elles-mêmes avec un objet vide, les métadonnées sont entièrement supprimées.
</Warning>

<div id="merge-user-metadata">
  ### Fusionner les métadonnées utilisateur
</div>

Seules les propriétés à la racine sont fusionnées dans l’objet. Toutes les propriétés de niveau inférieur sont remplacées.

Par exemple, pour ajouter l’adresse professionnelle d’un utilisateur comme sous-propriété supplémentaire, vous devez inclure le contenu complet de la propriété `addresses`. Comme l’objet `addresses` est une propriété à la racine, il sera fusionné dans l’objet JSON final représentant l’utilisateur, mais pas ses sous-propriétés.

```json lines theme={null}
{
  "user_metadata": {
    "addresses": {
      "home": "123 Main Street, Anytown, ST 12345",
      "work": "100 Industrial Way, Anytown, ST 12345"
    }
  }
}
```

Par conséquent, l’appel `PATCH` correspondant à l’API serait le suivant :

<AuthCodeGroup>
  ```bash cURL theme={null}
  curl --request PATCH \
    --url 'https://{yourDomain}/api/v2/users/user_id' \
    --header 'authorization: Bearer MGMT_API_ACCESS_TOKEN' \
    --header 'content-type: application/json' \
    --data '{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345", "work": "100 Industrial Way, Anytown, ST 12345"}}}'
  ```

  ```csharp C# theme={null}
  var client = new RestClient("https://{yourDomain}/api/v2/users/user_id");
  var request = new RestRequest(Method.PATCH);
  request.AddHeader("authorization", "Bearer MGMT_API_ACCESS_TOKEN");
  request.AddHeader("content-type", "application/json");
  request.AddParameter("application/json", "{"user_metadata": {"addresses": {"home": "123 Main Street, Anytown, ST 12345", "work": "100 Industrial Way, Anytown, ST 12345"}}}", ParameterType.RequestBody);
  IRestResponse response = client.Execute(request);
  ```

  ```go Go theme={null}

Vous pouvez supprimer `user_metadata` :

```json lines theme={null}
{
  "user_metadata": {}
}
```

<div id="app-metadata">
  ## Métadonnées d’application
</div>

Modifier les métadonnées à l’aide d’un objet vide les supprime complètement. Par exemple, l’envoi de ce corps de requête supprime tout le contenu de `app_metadata` :

```json lines theme={null}
{
  "app_metadata": {}
}
```

<div id="client-metadata">
  ## Métadonnées de l’application
</div>

<div id="create-applications-with-client-metadata">
  ### Créer des applications avec des métadonnées d’application
</div>

Un objet `clientMetadata` peut être inclus lors de la création d’une nouvelle application au moyen du point de terminaison des applications `POST /api/v2/`.

<div id="read-client-metadata">
  ### Consulter les métadonnées de l’application
</div>

Les métadonnées de l’application figurent dans la réponse des points de terminaison `GET /api/v2/clients` et `GET /api/v2/client/{id}`.

<div id="update-client-metadata">
  ### Mettre à jour les métadonnées de l’application
</div>

Les métadonnées de l’application peuvent être mises à jour à l’aide de l’endpoint [`PATCH /api/v2/clients/{id}`](https://auth0.com/docs/api/management/v2#!/Users/patch_users_by_id), en fournissant un objet d’application avec la propriété `clientMetadata`, dont la valeur est un objet contenant les métadonnées que vous souhaitez modifier.

**Application avant :**

```json lines theme={null}
{
  ...
  "name": "myclient",
  "client_metadata": {
    "mycolor": "red",
    "myflavor": "grape"
  }
  ...
}
```

Requête : `PATCH /api/v2/client/myclientid123` avec le corps suivant :

```json lines theme={null}
{ "client_metadata": { "mycolor": "blue" } }
```

**Application après :**

```json lines theme={null}
{
  "name": "myclient",
  "client_metadata": {
    "mycolor": "blue",
    "myflavor": "grape"
  }
  ...
}
```

<div id="delete-client-metadata-properties-and-values">
  ### Supprimer des propriétés et des valeurs de métadonnées d’application
</div>

Les clés de métadonnées d’application peuvent être supprimées au moyen d’une requête PATCH, comme indiqué dans « Update app\_metadata » ci-dessus, en fournissant toutefois `null` comme valeur de clé. Ce comportement correspond à celui des propriétés `user_metadata` et `app_metadata` de l’endpoint `PATCH` [/api/v2/users/{id}](https://auth0.com/docs/api/management/v2#!/Users/patch_users_by_id).
