Hosted checkout
Your buyers check out on
yourshop.shoppex.io or through the Shoppex Embed SDK. Zero backend
work — you just create products.Developer API
Drive everything from your own backend. Create invoices, manage customers, fulfill orders,
push events.
Storefront SDK
A typed JavaScript SDK that wraps the public Storefront API. Build a custom storefront
against Shoppex’s catalog and cart.
Theme platform
Build or fork a Shoppex theme. Includes the AI-native theme editor, hosted preview, and the
full theme runtime.
Pick where to start
If you have a buyer paying for digital goods today, start with the hosted checkout — you’ll be selling within an hour. If you have an existing app that needs to charge users, jump straight to the Developer API. You’ll create invoices, redirect to checkout, and listen for webhooks. If you have a frontend team and want a custom storefront, use the Storefront SDK on top of the public storefront API. If you want to redesign or ship a new storefront theme, use the theme platform.Core concepts
Invoices
The unit of payment. Every transaction creates an invoice with a lifecycle from
pending to
paid (or void).Payments
Three ways to take money: the hosted storefront, payment links, and the API. Same invoice
model under the hood.
Subscriptions
Recurring invoices with retries, trials, and plan changes.
Webhooks
Real-time event delivery. Sign verification, retries, and the full event reference.
