Digital downloads

Digital Downloads for Medusa

@makecrypto/medusa-plugin-digital-downloads adds a native Medusa v2 domain for digital releases, protected files, durable purchase entitlements, download and stream grants, and software licenses.

Medusa remains the source of truth for products, variants, prices, carts, orders, customers, payment, tax, promotions, and fulfillment. The plugin links digital configuration to those records instead of creating a second commerce stack.

Buyer-controlled license reveal

Digital delivery in native order history

Automated post-purchase email

Email layout, branding, provider credentials, and transport remain owned by the host application's Medusa Notification Module. The plugin supplies durable delivery events, template data, retry state, and copy-ready provider/template examples.

See the Medusa Admin guide for the complete merchant workflow and the storefront guide for authenticated, per-order, guest, download, and license integration.

Architecture

The plugin domain is organized around:

• Medusa product/variant-linked digital configuration;
• immutable releases containing protected/preview assets, or a zero-asset license boundary backed by an enabled generated or pooled license policy;
• local private storage and private S3/S3-compatible storage;
• durable entitlements linked to Medusa orders, line items, and customers;
• opaque, short-lived asset grants separate from ownership;
• generated or imported license keys, assignments, activations, and audit records;
• idempotent fulfillment state and notification delivery records;
• supported Medusa Admin extensions and a typed Store API client;
• accessible, style-light React product-preview and customer-library primitives.

The package does not provide DRM, a hosted storefront, a replacement checkout, or a payment provider. Public previews are separate from protected master assets.

Compatibility

• Node.js 20 or newer
• PostgreSQL through the Medusa host application
• @medusajs/medusa, Framework, Admin SDK, and icons >=2.18 <3
• @medusajs/ui >=4 <5
• React and React DOM >=18.3.1 <20 for supplied storefront/Admin UI

The plugin is built and host-tested against Medusa 2.18 and runs source CI on Node.js 20 and 22. Test the exact Medusa/plugin combination before production upgrades.

Install

Install from npm in the Medusa backend:

npm install @makecrypto/medusa-plugin-digital-downloads

For reproducible deployments, commit your lockfile or pin an approved version. Verified tarballs, .sha256 checksums, CycloneDX SBOMs, and build-provenance attestations are available from GitHub Releases. Verify the selected channel and package integrity during every deployment; see RELEASE.md.

Register it in medusa-config.ts. This minimal local-storage example uses a persistent directory outside any publicly served tree:

1import { defineConfig } from "@medusajs/framework/utils"
2
3export default defineConfig({
4  plugins: [
5    {
6      resolve: "@makecrypto/medusa-plugin-digital-downloads",
7      options: {
8        encryptionKey: process.env.DIGITAL_DOWNLOADS_ENCRYPTION_KEY,
9        tokenSecret: process.env.DIGITAL_DOWNLOADS_TOKEN_SECRET,
10        storage: {
11          defaultProvider: "local",
12          local: {
13            rootPath: process.env.DIGITAL_DOWNLOADS_LOCAL_ROOT,
14            signingSecret:
15              process.env.DIGITAL_DOWNLOADS_LOCAL_SIGNING_SECRET,
16          },
17        },
18      },
19    },
20  ],
21})

Generate independent secrets and store them in the deployment's secret manager:

1openssl rand -hex 32 # encryption key
2openssl rand -hex 32 # token secret
3openssl rand -hex 32 # local descriptor signing secret

The encryption key must be exactly 64 hexadecimal characters representing 32 random bytes. Generate it independently from the token secret; the plugin rejects configurations where both values are identical. Token and local signing secrets remain arbitrary UTF-8 values containing at least 32 bytes.

Keep DIGITAL_DOWNLOADS_ENCRYPTION_KEY stable. Existing encrypted license keys cannot be recovered after it is lost or replaced without a supported re-encryption migration.

Apply the packaged module migrations from the Medusa application:

npx medusa db:migrate

Then restart the Medusa API and worker processes. See docs/CONFIGURATION.md for complete local and S3 examples and docs/MIGRATIONS.md before a production upgrade.

S3-compatible storage

Choose S3 as the default provider and supply a private bucket:

1{
2  resolve: "@makecrypto/medusa-plugin-digital-downloads",
3  options: {
4    encryptionKey: process.env.DIGITAL_DOWNLOADS_ENCRYPTION_KEY,
5    tokenSecret: process.env.DIGITAL_DOWNLOADS_TOKEN_SECRET,
6    storage: {
7      defaultProvider: "s3",
8      s3: {
9        bucket: process.env.DIGITAL_DOWNLOADS_S3_BUCKET!,
10        region: process.env.DIGITAL_DOWNLOADS_S3_REGION || "us-east-1",
11        endpoint: process.env.DIGITAL_DOWNLOADS_S3_ENDPOINT,
12        accessKeyId: process.env.DIGITAL_DOWNLOADS_S3_ACCESS_KEY_ID!,
13        secretAccessKey:
14          process.env.DIGITAL_DOWNLOADS_S3_SECRET_ACCESS_KEY!,
15        sessionToken: process.env.DIGITAL_DOWNLOADS_S3_SESSION_TOKEN,
16        prefix: process.env.DIGITAL_DOWNLOADS_S3_PREFIX || "digital-downloads",
17        forcePathStyle:
18          process.env.DIGITAL_DOWNLOADS_S3_FORCE_PATH_STYLE === "true",
19      },
20    },
21  },
22}

The bucket must not be public. Restrict credentials to the configured bucket and prefix. Use HTTPS; insecure endpoints are intended only for deliberate local MinIO-style development.

Merchant workflow

After the plugin and migrations are installed, its Medusa Admin extensions are the merchant entry point. The intended flow is:

1. Select a Medusa product and variants.
2. Create digital configuration and a draft release.
3. Upload protected assets and add explicitly public previews. A license-only release may have an empty asset set when it has an enabled generated or pooled license policy.
4. Configure delivery limits and an optional license policy.
5. Publish a ready release.
6. Complete checkout using normal Medusa storefront/payment behavior.
7. Inspect issued entitlements on the order or in Digital Downloads Admin.
8. Revoke, reissue, or investigate access through audited actions.

Every digital product, including a license-only product, requires a current published release before fulfillment. Download, stream, and mixed releases must contain the ready deliverables required by their delivery type; license-only releases may publish with zero assets when an enabled generated or pooled license policy supplies the deliverable. Publishing with notify_existing_customers: true is intentionally unsupported until explicit entitlement update-policy semantics ship; use the default false value.

The exact Admin surfaces available in the installed build are documented in docs/ADMIN_GUIDE.md.

Entitlement lifecycle

Each digital configuration chooses when fulfillment becomes eligible:

• payment_captured waits for Medusa's captured-payment state/event;
• order_completed waits for the order-completed state/event;
• manual waits for the authenticated Admin order-issue action;
• configurations created without an explicit strategy use order.placed.

The placed, completed, and captured subscribers converge on the same durable fulfillment operation. A five-minute reconciliation job retries pending, failed, or stale leased work. Order cancellation, payment refund, and chargeback/dispute subscribers apply the configured revocation policy. When the host configures an email provider and the documented templates, delivery notifications use a durable outbox and a separate two-minute retry job. Email failure never rolls back ownership.

Order issuance and order-wide revocation share one order lock. A selected refund/revocation commits every entitlement state change, capability/license invalidation, and its notification outbox rows in one transaction. Reissuing an expired entitlement renews its recorded purchase term by default (or uses an explicit replacement deadline) so the restored active state is usable. The hourly expiry job also scans a separately bounded terminal batch and atomically repairs missing expiry/revocation outboxes from legacy or interrupted lifecycle writes. It rechecks status and deadlines under the entitlement lock.

The optional zero-cost Digital delivery Fulfillment Module provider can expose digital delivery in Medusa's native fulfillment UI. It does not issue entitlements itself and does not replace the event subscribers or cart completion. Registration and refund-policy details are in docs/CONFIGURATION.md.

Storefront

The optional storefront export provides a Fetch transport, a Medusa SDK adapter, TypeScript response types, hooks, and accessible React primitives:

1import {
2  createDigitalDownloadsFetchClient,
3} from "@makecrypto/medusa-plugin-digital-downloads/storefront"
4
5const digitalDownloads = createDigitalDownloadsFetchClient({
6  baseUrl: process.env.NEXT_PUBLIC_MEDUSA_BACKEND_URL!,
7  publishableKey: process.env.NEXT_PUBLIC_MEDUSA_PUBLISHABLE_KEY,
8  authToken: async () => getCustomerToken(),
9  credentials: "include",
10})

See docs/STOREFRONT.md for customer/guest authentication, React examples, grant handling, and security guidance. See docs/API.md for the backend contract.

Use DigitalLibrary for the authenticated account-wide purchase library and DigitalOrderDownloads inside Medusa's native customer order-detail view. Both surface protected files and buyer-controlled license reveal without replacing the host's account, checkout, or order-history implementation.

React customer resources require a changing, non-secret identityKey so cached state cannot cross a login/account boundary. Guest flows send { token, email? }; order-email matching is enabled by default, so storefronts should prompt for the order email and send it as email on access/grants and guest_email on guest license reveal. The guest purchase capability lifetime is configured separately from short-lived content grants and defaults to about 30 days. The built-in browser opener is a convenience for safe content up to 64 MiB; use the streaming BFF pattern for larger or seekable assets.

MakePay interoperability

Digital Downloads is payment-provider agnostic. It works alongside the separate @makecrypto/medusa-plugin-makepay payment provider because both use normal Medusa payment/order lifecycle events:

• configure MakePay under Medusa's Payment Module;
• configure MakePay credentials only in that provider;
• redirect the buyer to MakePay's hosted checkout from the normal Medusa payment session;
• let the signed MakePay webhook update Medusa payment state;
• let Digital Downloads issue ownership from the configured Medusa lifecycle signal.

Do not pass MakePay API or webhook secrets to Digital Downloads. The two packages have no secret-sharing or direct runtime dependency.

Security baseline

• Store protected files outside public web roots and keep S3 buckets private.
• Never log or persist plaintext download/guest capabilities.
• Never expose local paths, S3 keys, credentials, token hashes, or encrypted license values through Store API projections.
• Use HTTPS for the Medusa backend, storefront, and object storage.
• Configure a stable privacy salt and distributed rate limiting for a multi-instance production deployment where supported.
• Back up PostgreSQL, protected objects, configuration, and encryption material as separate recovery layers.
• Test customer-versus-customer, guest, refund, expiry, revocation, duplicate event, and byte-range edge cases before launch.
