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 browser-safe SDK for headless storefronts you host yourself. Use it outside the
Shoppex hosted theme runtime.
Theme platform
Build your hosted storefront visually in the Theme Builder or update its
ThemeDocument settings with scoped AI and API tooling.
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 you host yourself, use the Storefront SDK on top of the public storefront API. If you want to redesign or ship the Shoppex-hosted storefront, customize its ThemeDocument visually in the Builder or use the CLI, Dev API, and AI tooling for structured settings changes.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.
