Preparing Your Application:

• Select your application from the right-hand menu on http://www.facebook.com/developers
• Click "Edit Settings"
• Click "Advanced" from the left-hand menu and set "OAuth 2.0 for Canvas" to "Enabled"
• Click "Save Changes"
• Click "Credits" from the left-hand menu and enter all relevant information.

Passing Product Information: The purpose of this example is to demonstrate basic functionality of a credits transaction. For purposes of clarity and ease, this example passes critical parameters such as a price in the transaction directly. In order to prevent users from manipulating these fields through Firebug, you should only pass an internal key that points to a products table in your database that stores information such as price and product type. For example, if you pass "332" your callback.php script would perform a lookup of that value to return the proper item information.
