Digital fulfillment
The automatic post-payment handoff that gives a buyer secure access to a download, course, license, or other digital purchase.

What it is
Digital fulfillment is the automated handoff after a digital purchase: grant an entitlement, show a download or access page, and send a receipt with a way back in. There is no box, but the order still needs a fulfillment event that answers who can access which file, version, course, license, or account feature.
Reach for it whenever payment should unlock something immediately. Keep the entitlement separate from the email so a lost message does not mean a lost purchase, and let signed-in customers retrieve past purchases from their account.
Gotcha: a permanent public file URL turns one purchase into a shareable link, while email-only delivery strands anyone whose message is filtered. Use expiring signed links backed by durable entitlements, make payment webhooks idempotent, and define what refunds, chargebacks, file updates, and download limits do before the first order arrives.

Build digital fulfillment for files sold through Stripe Checkout. Verify the webhook signature, handle `checkout.session.completed`, and create one entitlement per purchased file keyed by customer and order. Make the handler idempotent on the Stripe Event ID so retries never duplicate entitlements or email. Show an authenticated download page after payment, polling the entitlement endpoint while the webhook finishes, and include the same account link in the receipt. Generate an Amazon S3 presigned GET URL only when an authorized buyer clicks Download, expire it after 10 minutes, and never expose the bucket object URL. Record download attempts, support versioned replacement files, and revoke future access on a refunded or charged-back order without pretending an already downloaded copy can be recalled.
