    Hi,

    I'm trying to connect to Genesys cloud using SDK version 137.0.0 Using the following code I can't authenticate when I'm on a enterprise network with proxy (with variable useProxy=true). However, when I'm using a direct connection without proxy (useProxy=false) it works fine:

    public static void initializePurecloudInstance() { * System.out.println("Initializing PureCloud instance...");* * if (useProxy){*

        • Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(PROXYURL, PROXYPORT)); *

    * apiClient = ApiClient.Builder.standard().withBasePath(PURECLOUDURL).withAuthenticatedProxy(proxy,proxyUser,pass).build();* * }* * else{* * apiClient = ApiClient.Builder.standard().withBasePath(PURECLOUDURL).build();*

        • } *

    * Configuration.setDefaultApiClient(apiClient);* * try {* * ApiResponse<AuthResponse> authResponse = apiClient.authorizeClientCredentials(CLIENTID, CLIENTSECRET);* * System.out.println("...Done. TOKEN EXPIRES ON "+authResponse.getBody().getExpires_in()+" SECONDS");* * } catch (ApiException e) {* * System.out.println("Error: "+e.getLocalizedMessage()+e.toString());* * e.printStackTrace();* * System.out.println(e.getRawBody());* * } catch (IOException e) {* * System.out.println("Error: "+e.getLocalizedMessage()+e.toString());* * e.printStackTrace();* * System.out.println(e.getMessage());* * }* * }*

    This is the consule log. What means "no client id provided"? the contants CLIENTID CLIENTSECRET are correctly informed.

    Please, could you assist? Thanks!

    Hi again,

    Could it be that the proxy is dropping the authentication headers? When I use a valid token directly it works:

    System.out.println("Initializing PureCloud instance..."); *Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(PROXYURL, PROXYPORT)); * apiClient = ApiClient.Builder.standard().withBasePath(PURECLOUDURL).withAuthenticatedProxy(proxy,proxyUser,proxyPass).build(); *Configuration.setDefaultApiClient(apiClient); apiClient.setAccessToken("<<<valid access token>>>"); AnalyticsApi api = new AnalyticsApi(); api.....

    Hi Carlos,

    Thanks for posting. In reviewing the SDK we do not currently support NTLM for proxy authentication. I am going to chat with our product manager today and open a ticket for my dev team to add support. I can't commit to a date on when we would do this work.

    Thanks, John Carnell

    Hi,

    I found a solution here: https://www.stefanbruhns.tech/make-http-get-post-requests-java/

    private static String obtenerNuevoToken() throws Exception { HttpPOSTRequest request = new HttpPOSTRequest(); request.domain = Config.PURECLOUDLOGINDOMAIN; request.port = 443; request.isHttps = true; request.setResource("/oauth/token"); HashMap<String, String> headers = new HashMap<String, String>(); headers.put("Content-Type", "application/x-www-form-urlencoded"); request.headers = headers; request.setData("granttype=clientcredentials&clientid=" + Config.CLIENTID + "&clientsecret=" + Config.CLIENTSECRET); HashMap<String, String> params = new HashMap<String, String>(); request.params = params; ProxyAuthenticator authenticator = new ProxyAuthenticator(Config.PROXYUSER, Config.PROXYPASS); ProxyFactory proxyFactory = new ProxyFactory(Config.PROXYURL, Config.PROXYPORT, authenticator); HttpConnector connector = new HttpConnector(proxyFactory.getProxy()); HttpResponse response = connector.makeRequest(request); return new String(response.content);

    }

    this method returns the json with the token info that you should parse
