1 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences Facebook API Teppo Räisänen School of Business and Information Management

2 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences FBML and FBJS  API = application programming interface  It is a way to utilize Facebook core features and user data

3 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences FBML and FBJS  FBML is similar to HTML  FBJS is similar to JavaScript  API-calls are close to PHP-function calls  The reason for that is that we use Facebook’s PHP-API

4 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API -calls require_login(); print $user; ?>

5 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API  API-calls allow developers to utilize Facebook core features and data  “get the user’s friends”  “get/set user’s status”  “Publish data to user’s profile”  “Make a SQL-query to Facebook database”  You don’t have to use them  They do allow more complicated applications!

6 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API   Facebook is constantly developing the API  The examples here use REST API   Graph API is the new version 

7 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences REST API  Administrative methods  Handles application and user data  Examples  admin.banUsers  admin.getMetrics  Login/Auth methods  Logins and session handling  Usually you don’t need to use this  Example  auth.expireSession

8 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences REST API  Data retrieval methods  Data handling  Most often used part of the API  Examples  friends.get, status.get  users.getInfo  Publishing methods  Publish data on profile/home page  Important for viral growth!  Examples  stream.publish  status.set

9 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences REST API  Facebook Connect methods  For using Facebook Connect  Mobile methods  Sending SMS  Dashboard API methods  Handles dashboard calls  dashboard.addNews  Events API methods  Handles Facebookin events  Events.create  Custom Tags API methods  Handles custom made tag calls

10 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API-calls in PHP  You utilize the API-calls in PHP like this 1.Create a facebook-instance from Facebook class 2.$facebook->api_client->FUNCTION_CALL();

11 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API-calls from PHP $facebook = new Facebook($apikey, $secret); $facebook->api_client-> users_getInfo($user, “first_name”);  Note, that users.getInfo is:  users_getInfo  Usually API-calls return an array

12 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API-calls from PHP $user_details = $facebook->api_client-> users_getInfo($user, 'last_name, first_name’); $firstname=$user_details[0]['first_name']; $lastname=$user_details[0]['last_name']; print “Your name is $firstname $lastname”;

13 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API-call examples Get all $user’s friends: $friends= $facebook->api_client->friends_get($user); Get all $user’s photos: $photos = $facebook->api_client->photos_get($user,'',''); Set status: $facebook->api_client->users_setStatus("facebook coding");

14 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API-calls in PHP  Some API-calls require special permissions  status update  Retrieving data does not usually need permission  bml/prompt-permission/ bml/prompt-permission/  publish_stream, read_stream  , read_mailbox  offline_access  create_event, rsvp_event  sms  status_update  photo_upload, video_upload  create_note  share_item

15 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences API-calls in PHP You can chech the permission with users.hasAppPermission $facebook->api_client- >users_hasAppPermission('status_update');  Returns 1, is there is permission to status update. 0 if not You can ask permission with fb:prompt-permission FBML- tag: Permit the app to update your status? You can use many permissions at the same time: Permit the app to publish to stream and update your profile?

16 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences FQL  Facebook Query Language – FQL   Allows SQL-querys to Facebook database  $sql = “SELECT name, pic FROM user WHERE uid= ”;  $results = $facebook->api_client->fql_query($sql);

17 OULU ADVANCED RESEARCH ON SOFTWARE AND INFORMATION SYSTEMS Teppo Räisänen | Oulu University of Applied Sciences Facebook Tools  Facebook has few tools that can be used to test e.g. FBJS 
