Shopify lacks native digital product support, so install an app like Sky Pilot or Fileflare. Upload your file, link it to a product, and configure download limits (3–5 is standard) and link expiry (48–72 hours). Delivery emails send automatically after payment.

Install the free License Manager for WooCommerce plugin, bulk import your keys, and link the key pool to a product. The plugin delivers keys in the order confirmation email and the customer's account page after payment completes.

Use getSignedUrl from @aws-sdk/s3-request-presigner with a GetObjectCommand and expiresIn set to 60 seconds. Generate the URL fresh on each download request after verifying the order's access record, expiry date, and download count.

Double-assignment happens when key selection and status update run as separate queries. Wrap the findFirst and update in a single database transaction with an atomic status check so concurrent orders cannot claim the same key.

Deliver only after payment confirmation, triggered from the payment success webhook such as Stripe's payment_intent.succeeded event. Never trigger delivery from order creation, since card declines can occur after the order is created.

Native tools handle basic file downloads but lack complex license key management and subscription-gated content libraries. For those cases, build custom delivery with S3 presigned URLs or combine apps like Sky Pilot with Recharge for subscription access.
