This document summarizes how to use Yahoo's social APIs and build social applications. It discusses two ways to access social APIs - via open applications that run on Yahoo's network or standalone OAuth applications. It provides examples of using Yahoo Query Language (YQL) to fetch user profile data, contacts, updates, and execute queries. Code samples are given in PHP and Python to perform OAuth authorization and make REST calls to fetch and insert social data.

8. Leverage Yahoo!’s 600+ million
users in your social
applications
with Yahoo!’s Social APIs.

9. Two ways to hack Social APIs
Open applica/ons are applica/ons
that run on the Yahoo! network or
other open social containers
OAuth applica/ons are standalone
applica/ons that run off the Yahoo!
network.

10. Easiest way to use
Social APIs is via
YQL

12. Fetching your profile data
select * from social.profile
where guid=me;

13. Profile Data

14. Finding your contacts
select * from social.contacts
where guid=me;

15. Contacts

16. Fetching any user’s profile data
select * from social.profile
where guid=
‘7VABDKK365VEHCUDYFO6HUSKQM’;

17. Fetching your updates
select * from social.updates
where guid=me;

18. Updates

19. Updates from your contacts
select * from
social.contacts.updates where
guid=me;

query=’iPad';

24. Updates associated with
huffingtonpost.com
select * from
social.updates.search where
link='huffingtonpost.com';

25. Tweets in Yahoo! Updates
select * from
social.updates.search where
source = 'twitter';

26. Updates from your application
select * from
social.updates.search where
source = '7BNRkt42';

• INSERT INTO meme.user.posts (type, content,
caption) VALUES ("photo", "http://www.yahoo.com/
myphoto.jpg", "this is the photo caption”)
• INSERT INTO meme.user.posts (type, content,
caption) VALUES ("video", "http://www.vimeo.com/

62. Social Data with YQL ‐ Recap
select * from social.profile where guid=me
select * from social.connections where
owner_guid=me
select message from social.profile.status
where guid=me
select * from social.updates where guid=me

63. PHP Example: ExecuTng YQL
$session = YahooSession::requireSession($key,
$secret, $app_id)
$results = $session->query(‘select * from
social.updates where guid=me’);
var_dump($results);

64. PHP Example: InserTng Updates
$session = YahooSession::requireSession ($key,
$secret, $app_id)
$user = $session->getSessionedUser();
$update = $user->insertUpdate($suid, $title,
$link, $description);
var_dump($update);

67. Appendix

68. What is OpenSocial?
• OpenSocial API
• For developing applicaTons on social
networks
• Accessing social data (profiles, connecTons)
• Fetching and inserTng acTviTes
• Implemented by many containers
• Develop once, distribute broadly

69. Python Example: OAuth Dance
oauthapp = yahoo.application.OAuthApplication (key,
secret, app_id, callback)
# fetch unauthorized request token
request_token = oauthapp.get_request_token(callback)
# authorize request token
authorization_url =
oauthapp.get_authorization_url(request_token)
# refresh authorized request token with access token
access_token =
oauthapp.get_access_token(request_token)
oauthapp.token = access_token

70. Python Example: Fetching Profile Data
oauthapp = yahoo.application.OAuthApplication(key,
secret, app_id, callback)
profile = oauthapp.getProfile()
print profile

71. Python Example: ExecuTng YQL
oauthapp = yahoo.application.OAuthApplication(key,
secret, app_id, callback)
results = oauthapp.yql('select * from social.profile where
guid=me')
print results
