Obtain Facebook Events using restfb - java

I need to obtain all public events from my fb page.
It's not possible using an App access token anymore: "Requires a valid Page or User access token with basic permissions." - https://developers.facebook.com/docs/graph-api/reference/page/events/
I don't want to put my User credentials into my Application.
Current code:
FacebookClient.AccessToken accessToken = new DefaultFacebookClient(Version.LATEST).obtainAppAccessToken(facebookProperties.getAppId(), facebookProperties.getAppSecret());
FacebookClient facebookClient = new DefaultFacebookClient(accessToken.getAccessToken(), Version.LATEST);
Date now = new Date();
Connection<com.restfb.types.Event> eventConnection = facebookClient.fetchConnection(facebookProperties.getPageId() + "/events", com.restfb.types.Event.class, Parameter.with("fields", "name,start_time"));
List<Event> events = eventConnection.getData().stream().filter(facebookEvent -> now.compareTo(Optional.ofNullable(facebookEvent.getEndTime()).orElse(facebookEvent.getStartTime())) <= 0).map(facebookEvent -> Event.fromFacebookEvent(facebookEvent)).collect(Collectors.toCollection(LinkedList::new));
A dirty Workaround would be creating a new fb account, adding it as a Page admin and provide its Credentials. Is there a better way to simply obtain the public Events?

DocuSign's Java SDK: Add 'Recipient Company Name' to Signer/Recipient

DocuSigns' report section includes tables containing the column name Recipient Company Name
I had a look through all DocuSign models inside the SDK, but I couldn't find any way to fill this column. Is there a way to do so using the SDK?
This can only be filled if the recipient is either a :
Saved contact in your DocuSign account.
Has their own DocuSign account.
If your recipient is just a random email/name you added to a one-time envelope - there's no way to enter the company information.
You can update contacts in your account and add the company name, see this article I wrote about how to do that in 6 languages including Java:
(note the "Organization" field which is the compan)
// You will need to obtain an access token using your chosen authentication flow
Configuration config = new Configuration(new ApiClient(basePath));
config.addDefaultHeader("Authorization", "Bearer " + accessToken);
UsersApi usersApi = new UsersApi(config);
UserProfile userProfile = new UserProfile();
Contact contact = new Contact();
contact.setName("Inbar Gazit");
contact.setEmails(new java.util.ArrayList<String>());
contact.getEmails().add("inbar.gazit#docusign.com");
contact.setOrganization("DocuSign");
ContactPhoneNumber contactPhoneNumber = new ContactPhoneNumber();
contactPhoneNumber.setPhoneNumber("212-555-1234");
contactPhoneNumber.setPhoneType("mobile");
contact.setContactPhoneNumbers(new java.util.ArrayList<ContactPhoneNumber>());
contact.getContactPhoneNumbers().add(contactPhoneNumber);
ContactModRequest contactModificationRequest = new ContactModRequest();
contactModificationRequest.setContactList(new java.util.ArrayList<Contact>());
contactModificationRequest.getContactList().add(contact);
usersApi.postContacts(accountId, contactModificationRequest);

Error code AADSTS70000121 when using One Drive through Microsoft Graph in Java

I have a Java application that integrates with One Drive through Microsoft Graph. I followed the documentation and I am able to pass the authorisation step but when interrogating the API I get this error:
"AADSTS70000121: The passed grant is from a personal Microsoft account and is required to be sent to the /consumers or /common endpoint."
What am I missing?
This is the code I am using:
Get an authorisation token using the URL bellow
private static final String RESPONSE_TYPE = "code";
private static final String SCOPE = "openid%20Files.Read%20Files.ReadWrite%20Contacts.Read%20offline_access";
String authorizeUrl = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=" + CLIENT_ID
+ "&scope=" + SCOPE + "&response_type=" + RESPONSE_TYPE + "&redirect_uri=" + REDIRECT_URL;
Exchange the received authorization token
List<String> scopes = new LinkedList<String>();
scopes.add("https://graph.microsoft.com/.default");
AuthorizationCodeCredential authCodeCredential = new AuthorizationCodeCredentialBuilder()
.clientId(CLIENT_ID)
.clientSecret(CLIENT_SECRET)
.authorizationCode(authorizationCode)
.redirectUrl(REDIRECT_URL)
.build();
TokenCredentialAuthProvider tokenCredAuthProvider = new TokenCredentialAuthProvider(scopes, authCodeCredential);
GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider(tokenCredAuthProvider).buildClient();
User me = graphClient.me()
.buildRequest()
.get();
As you are using the personal account then please change the endpoint to consumers instead of common,
https://login.microsoftonline.com/consumers/oauth2/v2.0/authorize?

Error while creating google calendar event with a service account

I have a requirement of creating a google calendar event on a calendar and add other users as attendees to that event. The objective is to send calendar events to the application users without taking their consent ( O-Auth ).
After reading Google's documentation, I found out that I need a service account. So I created a project and a service account from one of the email addresses of our G-Suite, noreply#xxxxx.com and enabled calendar API for the same.
I created and downloaded a key pair ( JSON ) whose content is,
{
"type": "service_account",
"project_id": "*****",
"private_key_id": "bdbbcd**************49f77d599f2",
"private_key": "**"
"client_email": "******#*****.iam.gserviceaccount.com",
"client_id": "11083******576856",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/****dev%40*****kdev.iam.gserviceaccount.com"
}
And as per the documentation, I proceded to write authentication flow code,
public static GoogleCredential doOauth( String credsPath ) throws IOException
{
GoogleCredential credential = GoogleCredential.fromStream(new FileInputStream(credsPath))
.createScoped(Collections.singleton(CalendarScopes.CALENDAR));
System.out.println(credential);
return credential;
}
The credential object has most of the details from the key file. But, the fields, serviceAccountUser, accessToken, refreshToken, clientAuthentication and requestInitializer have null value. ( I am guessing something wrong here )
Now, using the credentialObject, I continued to write the code as per the documentation to create the event.
GoogleCredential credential = doOauth(CREDENTIALS_FILE_PATH);
Event event = new Event().setSummary("Google I/O 2015").setLocation("800 Howard St., San Francisco, CA 94103")
.setDescription("A chance to hear more about Google's developer products.");
final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
DateTime startDateTime = new DateTime("2020-12-28T09:00:00-07:00");
EventDateTime start = new EventDateTime().setDateTime(startDateTime).setTimeZone("America/Los_Angeles");
event.setStart(start);
DateTime endDateTime = new DateTime("2020-12-28T17:00:00-07:00");
EventDateTime end = new EventDateTime().setDateTime(endDateTime).setTimeZone("America/Los_Angeles");
event.setEnd(end);
String[] recurrence = new String[] { "RRULE:FREQ=DAILY;COUNT=2" };
event.setRecurrence(Arrays.asList(recurrence));
EventAttendee[] attendees = new EventAttendee[] { new EventAttendee().setEmail("myemailaddress#gmail.com.com") };
event.setAttendees(Arrays.asList(attendees));
EventReminder[] reminderOverrides = new EventReminder[] {
new EventReminder().setMethod("email").setMinutes(24 * 60),
new EventReminder().setMethod("popup").setMinutes(10), };
Event.Reminders reminders = new Event.Reminders().setUseDefault(false)
.setOverrides(Arrays.asList(reminderOverrides));
event.setReminders(reminders);
String calendarId = "primary";
Calendar service = new Calendar.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)
.setApplicationName("testapp").build();
event = service.events().insert(calendarId, event).execute();
System.out.printf("Event created: %s\n", event.getHtmlLink());
But, this resulted in the error,
{
"code" : 403,
"errors" : [ {
"domain" : "calendar",
"message" : "Service accounts cannot invite attendees without Domain-Wide Delegation of Authority.",
"reason" : "forbiddenForServiceAccounts"
} ],
"message" : "Service accounts cannot invite attendees without Domain-Wide Delegation of Authority."
}
After spending time on Domain-Wide Delegation, I understood that this is needed if we have to send the event as other user from our g-suite, which is not needed for my problem. But, to debug, I went ahead and provided Domain-Wide Delegation and re ran the program. The same error came again.
So, I removed the invitees/attendees from the event object and re ran the application. This time the program ran without any error, but the event link generated, on click says, Could not find the requested event.
I do not see any examples of using the service account via java client libraries on the google developer link.
Can you please let me know what is going wrong here and the official/working documentation on how exactly to create a google calendar event from my project add other ( non g suite as well ) users to add as attendees, so that I do not have to get consent from other users to add events to their own calendar?
Thank You.
Fist off I want to say that this is something new, if you are seeing a lot of questions, and tutorials that did not state you needed to do this its because service accounts used to be able to send invites, this is something google locked down about a year ago.
This should work but i have not tested it as i no longer have access to a Gsuite account. You need to have the gsuite admin set up domain wide delegation to anther user. Then the service account needs to impersonate that user so it will appear as that user is the one sending the invites.
The only example I have for how that is added is in .net
.net example
var gsuiteUser = "se#clawskeyboard.com";
var serviceAccountCredentialInitializer = new ServiceAccountCredential.Initializer(serviceAccount)
{
User = gsuiteUser,
Scopes = new[] { GmailService.Scope.GmailSend, GmailService.Scope.GmailLabels }
}.FromCertificate(certificate);
Java example guess
I am not a java dev but the .net client library and the Java client library are very close in how they were developed. I would guess that you are looking for a method called setServiceAccountUser
GoogleCredential credential = new GoogleCredential.Builder().setTransport(HTTP_TRANSPORT)
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
.setServiceAccountScopes(CalendarScopes.CALENDAR)
.setServiceAccountPrivateKeyFromP12File(credsPath))
.setServiceAccountUser(gsuiteUser)
.build();
OAuth2 for Service Accounts
You should be able to impersonate the account user by setting the delegated variable to the user's email in the GoogleCredential object.
GoogleCredential credential = GoogleCredential.fromStream(new FileInputStream("credentials.json"))
.createScoped(<SCOPES>)
.createDelegated("user#example.com");

How to create bulkconnection with accesstoken in salesforce

I need to create BulkConnection for bulk API into salesforce.
We can able to create BulkConnection using ConnectorConfig with basic SOAP authentication.
Code is below,
ConnectorConfig config = new ConnectorConfig();
config.setUsername("USERNAME");
config.setPassword("PASSWORD+TOKEN");
config.setCompression(true);
config.setTraceFile("traceLogs.txt");
config.setTraceMessage(true);
config.setPrettyPrintXml(true);
config.setAuthEndpoint("https://login.salesforce.com/services/Soap/u/39.0");
PartnerConnection connection = new PartnerConnection(config);
String soapEndpoint = config.getServiceEndpoint();
String apiVersion = "39.0";
String restEndpoint = soapEndpoint.substring(0, soapEndpoint.indexOf("Soap/")) + "async/" + apiVersion;
config.setRestEndpoint(restEndpoint);
bulkConnection = new BulkConnection(config);
Above code is working fine.
But in my case, I can't able to collect username & password for each of the customer's salesforce account.
Is this possible to create BulkConnection using accestoken?..
Please give me your suggestion.
Thanks,
Harish

Facebook4j access token error 2500

I would like get data from facebook with facebook4j library, but I received this error
An active access token must be used to query information about the
current user. code - 2500
The code:
ConfigurationBuilder confBuilder = new ConfigurationBuilder();
confBuilder.setDebugEnabled(true);
confBuilder.setOAuthAppId("MY ID APP");
confBuilder.setOAuthAppSecret("MY APP SECRET");
confBuilder.setUseSSL(true);
confBuilder.setJSONStoreEnabled(true);
Configuration configuration = confBuilder.build();
FacebookFactory facebookFactory = new FacebookFactory(configuration );
Facebook facebookClient = facebookFactory.getInstance();
AccessToken accessToken = null;
OAuthSupport oAuthSupport = new OAuthAuthorization(configuration );
accessToken = oAuthSupport.getOAuthAppAccessToken();
facebookClient.setOAuthAccessToken(accessToken);
ResponseList<Post> feeds = facebookClient.getHome(new Reading().limit(1000));
You go to the following link: https://developers.facebook.com/tools/explorer/
There you choose your app, which you created and want to access from.
.setOAuthAccessToken("The User Access Token")
accessToken = oAuthSupport.getOAuthAccessToken(); // NOT AppAccessToken!!!
Then it should work
