FastSpring provides multiple, easy to use integration options from simple event notifications to full API integration. Our RESTful services and integration options can be used individually or combined providing you a full suite of tools. It is recommended that you review the Order Flow page before beginning your integration. If you are using subscription products, you should also review the Subscription Integration page.

The FastSpring API
The FastSpring API provides a set of endpoints that allow you to add or update products and coupons, create and access customer accounts, create sessions and orders, and manage subscriptions and your event integration. Adding tags and attributes that are returned in endpoint and webbook responses provides you with additional custom tracking capability specific to your website.
