​​eBay’s coded coupons tool is one of the newest products available for sellers to drive buyers to come back and purchase more items from their store. The tool allows more flexibility and control in offering discounts to prospective buyers, both on and off our marketplace.

With this new feature, sellers can create their own, custom discount codes that can be shared publicly on ebay.com or privately through their own marketing channels. Sellers can also print their coded coupons to include in shipped packages, helping to drive repeat purchases from their customers. Since the release of coded coupons in April, over one million buyers have made purchases on eBay using coded coupons.

This tool was developed by creating a new user experience stack using eBay’s latest technology stack — Raptor and MarkoJS. Here’s what we learned through the development of the tool’s system architecture and integrations, and how we overcame technical challenges along the way.
