# Transparent Commerce purchase flow

Use Transparent Commerce™ to instantly purchase a product on behalf of a customer during an authenticated customer session. This API bypasses calling the [Apply Shopper](https://www.digitalriver.com/docs/commerce-api-reference/#tag/Apply-Shopper) and [Submit Cart](https://www.digitalriver.com/docs/commerce-api-reference/#tag/Submit-Cart) resources separately and instantly purchases a single product. A typical example of a product purchased via this resource is an auto-renewal, such as a subscription.

The product direct purchase API performs the following actions with one Shopper call:

1. Adds a product to the cart.
2. Applies the default customer address to the cart.
3. Applies the default payment option to the cart.
4. Submits the cart.
5. Creates an order.
