Use Service Account with GoogleAdsClient to make AdWordsSession

I want to use Google Ads API with service account I managed to create a session using this Java code configuration:
ClassLoader classLoader = this.getClass().getClassLoader();
File configFile = new File(classLoader.getResource("ads.properties").getFile());
GoogleAdsClient googleAdsClient = GoogleAdsClient.newBuilder()
.fromEnvironment()
.fromPropertiesFile(configFile)
.build();
GoogleAdsServiceClient googleAdsServiceClient = googleAdsClient.getLatestVersion().createGoogleAdsServiceClient();
I want to use this connection to make a request using this code:
AdWordsSession session = null;
try {
// Generate a refreshable OAuth2 credential.
Credential oAuth2Credential = new OfflineCredentials.Builder()
.forApi(Api.ADWORDS)
.fromFile()
.build()
.generateCredential();
// Construct an AdWordsSession.
session =
new AdWordsSession.Builder().fromFile().build();
} catch (ConfigurationLoadException cle) {
System.err.printf(
"Failed to load configuration from the %s file. Exception: %s%n",
DEFAULT_CONFIGURATION_FILENAME, cle);
return;
} catch (ValidationException ve) {
System.err.printf(
"Invalid configuration in the %s file. Exception: %s%n",
DEFAULT_CONFIGURATION_FILENAME, ve);
return;
} catch (OAuthException oe) {
System.err.printf(
"Failed to create OAuth credentials. Check OAuth settings in the %s file. "
+ "Exception: %s%n",
DEFAULT_CONFIGURATION_FILENAME, oe);
return;
}
AdWordsServicesInterface adWordsServices = AdWordsServices.getInstance();
try {
runExample(adWordsServices, session);
} catch (ApiException apiException) {
System.err.println("Request failed due to ApiException. Underlying ApiErrors:");
if (apiException.getErrors() != null) {
int i = 0;
for (ApiError apiError : apiException.getErrors()) {
System.err.printf(" Error %d: %s%n", i++, apiError);
}
}
} catch (RemoteException re) {
System.err.printf(
"Request failed unexpectedly due to RemoteException: %s%n", re);
}
AdWordsServicesInterface adWordsServices, AdWordsSession session) throws RemoteException {
// Get the TrafficEstimatorService.
TrafficEstimatorServiceInterface trafficEstimatorService =
adWordsServices.get(session, TrafficEstimatorServiceInterface.class);

Do you know how I can use service account into the above code?

It looks like Adwords does support service account Authentication
OAuth2 service accounts
The AdWords API allows service account access through G Suite domains.
Which means you need to have your Gsuite domain admin authorize your service account to access it.
The Code should look something like this to authorize a service account
/**
* Initializes an adwords service object.
*
* #return An authorized adwords service object.
* #throws IOException
* #throws GeneralSecurityException
*/
private static AdWordsServices initializeAdWords() throws GeneralSecurityException, IOException {
HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
GoogleCredential credential = GoogleCredential
.fromStream(new FileInputStream(KEY_FILE_LOCATION))
.createScoped(AdwordsScopes.all());
// Construct the Analytics Reporting service object.
return new AdWordsServices.Builder(httpTransport, JSON_FACTORY, credential)
.setApplicationName(APPLICATION_NAME).build();
}

Java webservice client with ADFS SAML authentication

We are trying to connect to webservice (from Java) that has ADFS SAML authentication.
All the examples I have seen, use Basic Authentication over HTTPS. (I am just using HttpsURLConnection to make a request for now, not using anything like Axis or JAX-WS)
I am not sure how to approach ADFS SAML authentication. Here's what I understand so far (don't know much about SAML):
I make one request, pass username/password and get the
authentication token back
Save the authentication token
Pass the token as some SOAP attribute in my calls where I invoke an
actual operation on the webservice
No idea under which attribute would I put this authentication token though
Is my above approach correct? If so, is there some library that I can use that does all this?
If not how can I go about doing this manually?
Please let me know if there are other or better ways of going about this.

If you are trying to build native app then can use below code. i has tried to use power bi rest apis. once you gets token you can use that in api calls.
public class PublicClient {
private final static String AUTHORITY = "https://login.microsoftonline.com/common";
private final static String CLIENT_ID = "XXXX-xxxx-xxx-xxx-xxxX";
private final static String RESOURCE = "https://analysis.windows.net/powerbi/api";
public static void main(String args[]) throws Exception {
try (BufferedReader br = new BufferedReader(new InputStreamReader(System.in))) {
System.out.print("Enter username: ");
String username = br.readLine();
System.out.print("Enter password: ");
String password = br.readLine();
AuthenticationResult result = getAccessTokenFromUserCredentials(
username, password);
System.out.println("Access Token - " + result.getAccessToken());
System.out.println("Refresh Token - " + result.getRefreshToken());
System.out.println("ID Token Expires on - " + result.getExpiresOn());
}
}
private static AuthenticationResult getAccessTokenFromUserCredentials(
String username, String password) throws Exception {
AuthenticationContext context = null;
AuthenticationResult result = null;
ExecutorService service = null;
try {
service = Executors.newFixedThreadPool(1);
context = new AuthenticationContext(AUTHORITY, false, service);
Future<AuthenticationResult> future = context.acquireToken(
RESOURCE, CLIENT_ID, username, password, null);
result = future.get();
} finally {
service.shutdown();
}
if (result == null) {
throw new ServiceUnavailableException(
"authentication result was null");
}
return result;
}
}

Unable to have concurrent log-ins with Google auth

I have a web app where users have to authenticate using Google sign-in. I do this because I need to grab their email address. When they fill out the fields on the page, all that data is stored in a google sheet alongside their email address (for auditing purposes incase something is askew with the data). Unfortunately what's happening is that if user A signs in, and does some work and at the same time user B logs in, when user A submits data, they will be submitting user B's email address (as does user B). In short, the latest person to log in, that email address is used. There is no database and I'm not storing any cookies. When they refresh the page, they have to re-authenticate. I am using Angular 7 and Java. Here is the code that I used:
ngOnInit() {
gapi.load('auth2', () => {
this.auth2 = gapi.auth2.init({
client_id: 'CLIENT_ID_HERE',
// Scopes to request in addition to 'profile' and 'email'
scope: 'https://www.googleapis.com/auth/spreadsheets'
});
});
}
signInWithGoogle(): void {
this.auth2.grantOfflineAccess().then((authResult) => {
this.authCode = authResult['code'];
this.fetchData();
});
}
authCode is bound to the child component so it can be passed as query param to the java code for google auth.
this.seriesService.submitSeriesData(matchList, this.authToken).subscribe(res => {.....);
The google auth java code is so:
private static final String APPLICATION_NAME = "Google Sheets API Java";
private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
private static final List<String> SCOPES = Collections.singletonList(SheetsScopes.SPREADSHEETS);
private static final String CLIENT_SECRET_DIR = "/client_secret.json";
private static GoogleTokenResponse tokenResponse = null;
public static String getEmailAddress() throws IOException {
GoogleIdToken idToken = tokenResponse.parseIdToken();
GoogleIdToken.Payload payload = idToken.getPayload();
String email = payload.getEmail();
return email;
}
public static Sheets getSheetsService1(String token, String redirectUri) throws IOException, GeneralSecurityException {
// Exchange auth code for access token
InputStream in = GoogleAuthUtil.class.getResourceAsStream(CLIENT_SECRET_DIR);
GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
tokenResponse =
new GoogleAuthorizationCodeTokenRequest(
new NetHttpTransport(),
JacksonFactory.getDefaultInstance(),
"https://www.googleapis.com/oauth2/v4/token",
clientSecrets.getDetails().getClientId(),
clientSecrets.getDetails().getClientSecret(),
token,
redirectUri)
.execute();
String accessToken = tokenResponse.getAccessToken();
GoogleCredential credential = new GoogleCredential().setAccessToken(accessToken);
Sheets service = new Sheets.Builder(new NetHttpTransport(), JacksonFactory.getDefaultInstance(), credential)
.setApplicationName("MY APP HERE")
.build();
return service;
}
And the endpoint:
#RequestMapping(value="series/data", method = RequestMethod.POST, consumes="application/json")
public boolean submitSeriesMatchData(#RequestBody(required=true) SubmitStatsDto request) throws IOException, GeneralSecurityException, Exception {
if (service == null) {
service = GoogleAuthUtil.getSheetsService1(request.getToken(), this.redirectUri);
}
......
}
1) User clicks on the google sign in button
2) They select email and auth with google
3) I receive an auth code back and store it in ng.
4) Every REST call is passed said token to auth with google, and every endpoint calls getSheetsService1 which authenticates w/ token. (multiple endpoints, I only showed one above)
5) I get email from that tokenResponse.
Any ideas? This site will not have a database/users/local logins. Thank you.

Verify transaction on Google App Engine

I'm trying to get the transaction verification working for making an in-app purchase on Android in countries where Google Play isn't available.
When using the sandbox API everything seems to work well on my local Google App Engine dev server. The server sends a request to PayPal with the transaction ID and comes back with the JSON response containing the state of the transaction.
When I upload the code to Google App Engine, however, it instead uses the live API with corresponding credentials. When I do the transaction verification there, I get the following error from the Paypal REST SDK:
Response Code : 401 with response : {"error":"invalid_client","error_description":"The client credentials are invalid"}
In the HttpServlet I use this to set the constant DEBUG to true or false:
#Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
String dev = config.getServletContext().getServerInfo();
if (dev.contains("Development")) {
Constants.DEBUG = true;
} else {
Constants.DEBUG = false;
}
}
The transaction ID is verified with the code below. It gets the access token for making the API call and then verifies the transaction id. I also create a custom config which sets GOOGLE_APP_ENGINE to true and MODE to sandbox or live depending on the DEBUG constant (this is because I couldn't get the getServletContext().getResourceAsStream("sdk_config.properties") working as it gave an Access denied error).
public static String getAccessToken() throws PayPalRESTException {
String clientSecret, clientID;
if (Constants.DEBUG) {
clientSecret = Constants.CLIENT_SECRET_SANDBOX;
clientID = Constants.CLIENT_ID_SANDBOX;
} else {
clientSecret = Constants.CLIENT_SECRET_LIVE;
clientID = Constants.CLIENT_ID_LIVE;
}
return new OAuthTokenCredential(clientID, clientSecret,
getPaypalConfig()).getAccessToken();
}
public static Map<String, String> getPaypalConfig() {
Map<String, String> config = new HashMap<>();
config.put(com.paypal.core.Constants.GOOGLE_APP_ENGINE,
String.valueOf(true));
if (Constants.DEBUG) {
config.put(com.paypal.core.Constants.MODE,
com.paypal.core.Constants.SANDBOX);
} else {
config.put(com.paypal.core.Constants.MODE,
com.paypal.core.Constants.LIVE);
}
return config;
}
public static boolean payPalVerifier(String saleId)
throws PayPalRESTException {
if (accessToken == null) {
accessToken = Utils.getAccessToken();
apiContext = new APIContext(accessToken);
apiContext.setConfigurationMap(Utils.getPaypalConfig());
}
boolean completed = false;
Payment pay = Payment.get(apiContext, saleId);
for (Transaction transaction : pay.getTransactions()) {
for (RelatedResources relatedResources : transaction
.getRelatedResources()) {
if (com.pixplicity.Constants.DEBUG) {
completed = relatedResources.getSale().getState()
.equals("completed")
|| relatedResources.getSale().getState()
.equals("pending");
} else {
completed = relatedResources.getSale().getState()
.equals("completed");
}
}
}
return completed;
}
How do I solve this problem?

GWT Facebook Integration

I am trying to write a server side Facebook Notification service in my GWT app. The idea is that I will run this as a timertask or cron job sort of.
With the code below, I get a login URL, I want to be able to Login programmatically as this is intended to be automated (Headless sort of way). I was gonna try do a submit with HTMLunit but I thought the FB API should cater for this.
Please advice.
public class NotificationServiceImpl extends RemoteServiceServlet implements NotificationService {

String secret = notification.getSecret_key();
try {
// MDC.put(ipAddress, req.getRemoteAddr());
HttpServletRequest request = getThreadLocalRequest();
HttpServletResponse response = getThreadLocalResponse();
HttpSession session = getThreadLocalRequest().getSession(true);
// session.setAttribute("api_key", api_key);
IFacebookRestClient<Document> userClient = getUserClient(session);
if(userClient == null) {
System.out.println("User session doesn't have a Facebook API client setup yet. Creating one and storing it in the user's session.");
userClient = new FacebookXmlRestClient(api_key, secret);
session.setAttribute(FACEBOOK_USER_CLIENT, userClient);
}
System.out.println("Creating a FacebookWebappHelper, which copies fb_ request param data into the userClient");
FacebookWebappHelper<Document> facebook = new FacebookWebappHelper<Document>(request, response, api_key, secret, userClient);
String nextPage = request.getRequestURI();
nextPage = nextPage.substring(nextPage.indexOf("/", 1) + 1); //cut out the first /, the context path and the 2nd /
System.out.println(nextPage);
boolean redirectOccurred = facebook.requireLogin(nextPage);
if(redirectOccurred) {
return null;
}
redirectOccurred = facebook.requireFrame(nextPage);
if(redirectOccurred) {
return null;
}
try {
facebookUserID = userClient.users_getLoggedInUser();
if (userClient.users_hasAppPermission(Permission.STATUS_UPDATE)) {
userClient.users_setStatus("Im testing Facebook With Java! This status is written using my Java code! Can you see it? Cool :D", false);
}
} catch(FacebookException ex) {
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, "Error while fetching user's facebook ID");
System.out.println("Error while getting cached (supplied by request params) value " +
"of the user's facebook ID or while fetching it from the Facebook service " +

return null;
}
