Azure Graph API Authentication_MissingOrMalformed - azure

Question

I am using Azure Graph API to import users from Azure AD. In the azure portal I have added multiple Applications.
I am getting clientId, tenantId from protal and creating a secret key with one year expiry. Using these values I am creating an access_token and using that token connecting to AD.
Here is the code
public static String loginUrlPrefix = "https://login.windows.net/";
public static String loginUrlSufix = "/oauth2/token";
public static String importUrl = "https://management.core.windows.net/<subscription-id>/services/importexport/";
#SuppressWarnings("deprecation")
public static String getToken(String tenantId,String clientId,String encodedSecretKey) {
try {
String secretKey = EncryptionUtils.decryptAES(encodedSecretKey);
secretKey = URLEncoder.encode(secretKey);
String urltoConnect = loginUrlPrefix+tenantId+loginUrlSufix;
String payLoad = "resource=https%3A%2F%2Fmanagement.core.windows.net%2F&client_id="+clientId+"&grant_type=client_credentials&client_secret=" + secretKey;
URL url = new URL(urltoConnect);
URLConnection connection = null;
connection = url.openConnection();
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
connection.setDoOutput(true);
java.io.OutputStreamWriter wr = new java.io.OutputStreamWriter(connection.getOutputStream());
wr.write(payLoad);
wr.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
String content;
String html = "";
while ((content = br.readLine()) != null) {
if (!content.equals("") && content.length() != 0)
html += content.trim();
}
return html;
} catch (Exception e) {
e.printStackTrace();
try {
throw e;
} catch (Exception e1) {
e1.printStackTrace();
}
}
return null;
}
#SuppressWarnings("deprecation")
public static Boolean testADConnection(String accessToken,String tenant) {
try {
URL url = new URL(String.format("https://graph.windows.net/%s/tenantDetails?api-version=2013-04-05", tenant,
accessToken));
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// Set the appropriate header fields in the request header.
conn.setRequestProperty("api-version", "2013-04-05");
conn.setRequestProperty("Authorization","Bearer "+ accessToken);
conn.setRequestProperty("Accept", "application/json;odata=minimalmetadata");
String goodRespStr = HttpClientHelper.getResponseStringFromConn(conn, true);
System.out.println(goodRespStr);
int responseCode = conn.getResponseCode();
if(responseCode == 200){
return true;
}
else{
System.out.println(goodRespStr);
}
} catch (Exception e) {
e.printStackTrace();
try {
throw e;
} catch (Exception e1) {
e1.printStackTrace();
}
}
return false;
}
public static void main(String[] args){
String tokenJSON = getToken(tenantId,clientId,secretKey);
if(tokenJSON != null){
JSONObject j = (JSONObject) JSONValue.parse(tokenJSON);
String token = (String) j.get("access_token");
testADConnection(token,tenantId);
}
}
This works fine with the first application I added. But when I add a second application with the same configuration and permissions this is not working.
I am getting a 403 error
"odata.error": {
"code": "Authentication_MissingOrMalformed",
"message": {
"lang": "en",
"value": "Access Token missing or malformed."
},
"date": "2016-12-02T07:27:59", }
Tenant Id i am passing same for both the applications (copied from show diagnostics in help menu) client id I am copying whatever is generated in Azure and labelled as Application Id.Secret Key I am generating in Azure portal with 1 year validity.
