Five ways to deliver

Whatever you sell, it ships itself.

Pick a delivery type per product — or combine several. Every method fires the moment Stripe confirms payment.

Secure file delivery
文件/数据集

Datasets, reports, exports — stored privately and handed out as expiring, signed download links.

Signed URLs
Download caps
Checksums
Versioned releases
版本发布

Publish new releases over time; entitled buyers re-download current and historical versions with changelogs.

Immutable assets
Changelogs
Re-download
License keys
许可密钥

Generate a unique key per order, track activations, and revoke or rotate anytime.

Auto-generate
Activation limits
Revoke
API & MCP access
数据接口

Customer-scoped API keys and an MCP endpoint so buyers and AI agents query only the data they're entitled to.

Scoped keys
Rate limits
MCP tools
Usage logs
Email delivery
邮件发送

Send access, keys, and download links in a branded email from your own domain, with automatic resends.

Payment in. Product out. No you in the loop.

STEP 1
Buyer pays
On your site via Stripe Checkout — your branding, your domain.
STEP 2
Webhook verified
Touchwaves verifies the signed event. Payment is the source of truth.
STEP 3
Entitlement + delivery
A release, file, license key, API token, or email — granted automatically.
STEP 4
Buyer has access
Instant access page + email. Re-downloadable from the portal anytime.
Your system, not ours

Embed it in the site
you already own.

No hosted storefront you're locked into. Drop a buy button anywhere, or drive everything through a typed API and webhooks into your own app and database.

One-line buy button — Paste a snippet into any page — React, WordPress, plain HTML.
Typed API & SDK — Create products, issue grants, read deliveries from your backend.
Webhooks to your app — Mirror every delivery into your own database and tools.
checkout.tsx
// drop a buy button anywhere
import { BuyButton } from "@touchwaves/sdk"
 
<BuyButton
product="global-funding-dataset"
deliver="release" // file | release | license | api | email
onDelivered={(d) => db.grants.save(d)}
/>
Entitlement-checked access

Every download, API call, and key lookup checks the buyer’s entitlement — derived from payment, never from a redirect success page.

Webhook is the source of truth

Access is granted only after the signed Stripe webhook confirms payment, and revoked automatically on refund. Every event is idempotent.

Buyers keep access

A customer portal holds every purchase, release, license, and API key, with new versions appearing automatically.
