Delivery (PRO)
Instant, secure access to Starter Pro after purchase with controlled delivery and fulfillment flow.
Secure delivery after purchaseLink to section
Starter Free gives you a product surface.
Starter Pro gives you a real paid product flow with controlled delivery after purchase.
That matters because a digital product is not only about checkout.
It is also about what happens immediately after payment:
- access is confirmed
- delivery is controlled
- the buyer receives the product
- the asset is not publicly exposed
- fulfillment does not rely on manual work
One-time payment · Instant access after purchase
Billing system
Core idea
Checkout creates the purchase. Delivery completes the product experience.
What this solvesLink to section
A paid digital product feels fragile when delivery is manual or exposed through public links.
Buyers expect:
- secure payment
- instant confirmation
- controlled access
- reliable download
- no waiting for manual fulfillment
Starter Pro includes the foundations for a post-purchase delivery flow that feels serious, automated, and trustworthy.
What is includedLink to section
Fulfillment flow
A structured flow from successful payment to confirmed product access and download availability.
Controlled access
Backend-controlled download access so paid files are not exposed through permanent public URLs.
Token-based delivery
Secure token patterns for download access, expiration, validation, and post-purchase fulfillment.
Retry-safe operation
Delivery designed around backend confirmation, webhook truth, and resilience against interrupted browser sessions.
Delivery lifecycleLink to section
Buyer completes checkoutLink to section
Payment happens through Stripe Checkout.
Checkout is the commercial action, but the browser redirect alone should not be treated as the source of truth.
Webhook confirms the purchaseLink to section
Stripe sends the confirmed event to your backend.
checkout.session.completed
payment_intent.succeeded
invoice.payment_succeededThe backend verifies the event and updates the internal purchase or access state.
Access is grantedLink to section
The app associates the purchase with the buyer, customer, or user account.
This is where billing, auth, and backend ownership connect.
Download token is createdLink to section
A delivery token can be created for controlled access.
const token = await createDownloadToken({
userId,
productId: "starter-pro",
expiresIn: "24h",
});Backend serves the assetLink to section
The buyer requests the download through your backend.
The backend validates access and streams or redirects to a private file source without exposing a permanent public URL.
Production rule
Redirects are UX. Webhooks confirm purchase. Backend access controls delivery.
Secure delivery modelLink to section
Private storage
- paid files should not live behind public permanent links
- private storage keeps the asset away from direct exposure
- backend access can decide who gets the file
Access validation
- validate purchase or entitlement server-side
- connect access to user or customer identity
- avoid trusting client-only purchase state
Delivery token
- token represents controlled temporary access
- expiration limits long-term link sharing
- validation keeps delivery behind backend rules
Download endpoint
- buyer requests file through the app
- backend validates token and access
- asset is delivered without exposing private storage

Why this mattersLink to section
Delivery is the final step in the buyer journey.
If delivery is slow, manual, fragile, or unclear, the purchase experience feels less trustworthy.
A strong delivery system helps you:
- reduce support friction
- avoid manual fulfillment work
- protect paid assets
- improve buyer confidence
- scale sales without operational drag
Buyer trust principle
The buyer should never wonder what happens after payment. Confirmation and access should feel immediate, clear, and controlled.
Security rulesLink to section
Use these rules when adapting the delivery layer.
Prefer
- private storage for paid files
- server-side access validation
- webhook-confirmed purchase state
- expiring delivery tokens
- clear post-purchase confirmation copy
Avoid
- public permanent download links
- manual fulfillment as the default path
- trusting only redirect success
- emailing raw private asset URLs
- unclear buyer instructions after payment
Decision guideLink to section
Use Starter Pro delivery when:
- users can buy access
- paid files must stay private
- delivery should be automatic
- buyer access must be controlled
- fulfillment should not depend on manual work
- the purchase experience must feel complete
Starter Free is enough when:
- you are only validating product UX
- no one can buy yet
- delivery is not part of the product experience
- manual demos are still acceptable
Implementation checklistLink to section
Before treating delivery as production-ready, validate:
- checkout completion
- webhook confirmation
- purchase-to-access mapping
- private asset storage
- token creation
- token expiration
- token validation
- backend download route
- unauthorized access behavior
- expired token behavior

Delivery validation principle
A paid product is not complete when checkout works. It is complete when the buyer reliably receives controlled access.
