Payments with Gumroad, licensing with Keygen

In this example, we'll be working with a Node.js app that integrates Keygen and Gumroad together using Gumroad's custom delivery fulfillment method. This integration uses Gumroad to accept a one-time payment and generates a license key for the customer after a successful checkout. After purchase, the customer will be redirected to a success page which contains their license key which they can input inside of your product and a download link to our product distributed using Keygen Dist.

Note: This integration requires that you have an upgraded Gumroad account in order to use their "Custom Delivery" method. Please head over to Gumroad's website to learn more about that offering.
