36 /* Twitter Addon for Friendica
38 * Author: Tobias Diekershoff
39 * tobias.diekershoff@gmx.net
41 * License:3-clause BSD license
44 * To use this addon you need a OAuth Consumer key pair (key & secret)
45 * you can get it from Twitter at https://twitter.com/apps
47 * Register your Friendica site as "Client" application with "Read & Write" access
48 * we do not need "Twitter as login". When you've registered the app you get the
49 * OAuth Consumer key and secret pair for your application/site.
51 * Add this key pair to your global config/addon.config.php or use the admin panel.
54 * 'consumerkey' => '',
55 * 'consumersecret' => '',
58 * To activate the addon itself add it to the system.addon
59 * setting. After this, your user can configure their Twitter account settings
60 * from "Settings -> Addon Settings".
62 * Requirements: PHP5, curl
