Digital Downloads Pro automatically monitors your Shopify orders, looking for any order that contains products matching your Digital Products setup in the app.
When an order from Shopify contains a matching digital product, the system will create an order in Digital Downloads Pro.
The system will then check the order against the delivery and fraud prevention rules. If all of the rules pass, the digital content will be auto-delivered to the customer via email. If the rules do not pass, then the system will mark the status of the order, and continue to monitor the order for changes and updates, re-running the rules each time.
