====== Best Practices for E-Commerce Integration ======

===== User Integration =====
=== Where to register your users ===
User registration can happen either on your site or as the user actually completes a checkout. The first step is to determine which method makes more sense. If there's a reason for a user to register prior to allowing a checkout, you can use the [[docs:api|API]] and [[docs:single_sign_on|single sign-on]]. Create the user via the API when the user is created on your end, then use SSO to force a valid session prior to allowing through to checkout.

The alternate method would be to allow the users to register using the FoxyCart checkout. You'd then process the [[http://wiki.foxycart.com/docs:datafeed|XML datafeed]] to create the user immediately upon successful transaction.

You could use both approaches, but you'll want to make it clear via links and instructions to your users exactly what's going on.

=== Subscriptions and User Access ===
Regardless the method of user registration you choose (above), the basic idea is covered [[docs:subscription_datafeed#membership_subscription-based_site_permission_idea|here]].
