Embedded Checkout Starter Kit
A small, readable Cloudflare Worker that sells with Stripe embedded Checkout and fulfills only from signed webhooks. The redirect back to your site never counts as payment. Deploy it to staging in an afternoon, then work through the checklist to go live.
The ledger
A D1 order table written only by signed events, keyed so that replays and delayed-payment events collapse to one order. Refunds and disputes revoke.
The guides
A going-live checklist, a webhooks-and-idempotency guide, and field notes on the production failures the code is built to avoid.
Checkout is hosted by Stripe. After payment you are taken to a download page for a zip containing TypeScript source, a D1 migration, a node:test suite and three guides. The download link works for 30 days and up to 10 downloads. Requires a Stripe account and a Cloudflare account.
