How to get a list of all Auth0 users

Question

I want to get a list of Auth0 users from the Java API (auth0 client). Can I do it? Java-based API + Spring Security. I tried to do this using RestTemplate:

List findAllUsers(){
    String idToken = RestService.getIdToken()
    HttpHeaders headers = new HttpHeaders()
    headers.set("Authorization", "Bearer $idToken");
    List users = []
    try{
        ResponseEntity entity = restTemplate.exchange(issuer+"api/v2/users", HttpMethod.GET, new HttpEntity<Object>(headers), List)
        users = entity.getBody()
    } catch (HttpClientErrorException e){
        e.printStackTrace()
    }
    return users
}

But I get 403 Forbidden status.

Yes it is possible. However, you need to use Auth0 Management Token.

See this example. I wrote where I do a search (in this case, filtering to get a specific user account, not all users).

. read:users read:user_idp_tokens .

HTTP- Apache :

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.2</version>
</dependency>

:

HttpClient httpclient = new DefaultHttpClient();

                URIBuilder builder = new URIBuilder("https://domain.auth0.com/api/v2/users");
                HttpGet httpGet = new HttpGet(builder.build());
                httpGet.setHeader("Accept", "application/json");
                httpGet.setHeader("Content-type", "application/json");
                httpGet.setHeader(
                        "Authorization",
                        "Bearer "+ token);

                HttpResponse responseHttp = httpclient.execute(httpGet);

                HttpEntity entity = responseHttp.getEntity();

                BufferedReader rd = new BufferedReader(new InputStreamReader(entity.getContent()));

                StringBuffer result = new StringBuffer();

                String line = "";
                while ((line = rd.readLine()) != null) {
                    result.append(line);
                    System.out.println(line);
                }

50 , 50 , URL:

https://domain.auth0.com/api/v2/users?per_page=50&page="+ pageNumber + "&include_totals=true"

JSON, Gson:

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.7</version>
</dependency>

Json Gson:

 public String parse(String jsonLine) {
    JsonElement jelement = new JsonParser().parse(jsonLine);
    JsonObject  jobject = jelement.getAsJsonObject();
    jobject = jobject.getAsJsonObject("data");
    JsonArray jarray = jobject.getAsJsonArray("translations");
    jobject = jarray.get(0).getAsJsonObject();
    String result = jobject.get("translatedText").toString();
    return result;
}

Answer 3

Easy way with a rest pattern.

final String MANAGEMENT_TOKEN = "ManagementToken";
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.set("Authorization", "Bearer" + " " + MANAGEMENT_TOKEN);
        HttpEntity<Object> httpEntity = new HttpEntity<>(httpHeaders);
        String url = "https:<//YOUR_DOMAIN>.auth0.com/api/v2/users";
    ResponseEntity<Object>response=restTemplate.exchange(url,HttpMethod.GET,httpEntity, Object.class);

`

To develop MANAGEMENT_TOKEN

Hope this helps you.
