 Configuring Horde 4 for Facebook integration
----------------------------------------------

Horde's Facebook integration requires some setup on Facebook in order to get it to working. A Facebook application must be created for each Horde installation. The following are the steps that are required in order to get this working.

1. Create the application. This is done at http://facebook.com/developers

2. Under the *Website* section of the configuration, you need to add the url to your services/facebook page. So, if your horde install is at http://example.com/horde, then your *Site URL* setting should be *http://example.com/horde/services/facebook/ *. You also need to enter the *Site Domain* setting. In this example, it would be *example.com*.

3. Take note of the *Application ID* and the *Application Secret* values. You will need to enter these in Horde's *API Keys* configuration section.

4. Once those values are entered into Horde's configuration, users will be able to validate the application via Horde's *Facebook Integration* preference page.
