Customizing a tab with a specific URL on a Facebook Fan page using app_data

Facebook API docs say the app_data parameter should be used to set tabs on the Facebook Fan page.

However, when users add our tab to their page, the app_data parameter is lost every time, which means that the tabs are not configured on the fan page as they should be.

For example, we want this page to be displayed for one client: http://www.facebook.com/apps/application.php?id=198939416792674&sk=app_198939416792674&app_data=15

After the client adds this URL as a tab to their fan page, the tab URL loses the app_data parameter. The displayed page no longer reflects data specific to this client.

We need tabs containing a parameter specific to each fan page. We thought "app_data" was the right approach.

Any clues what are we doing wrong?

The best way to do what you are trying to achieve is to customize the content based on page['id'] , which is passed to you through a signed request .
