Stripe Connect Express onboarding for Node marketplaces
Account links, seller readiness, and destination Checkout without a blank-server start.
Stripe Connect Marketplace Kit is a $29 paid source kit for marketplace teams that need server-side onboarding links, connected-account capability checks, platform fees, and signed webhook reconciliation in one runnable Node package.
What the kit helps you wire
Onboarding state
Track the account fields that decide whether a seller can accept charges and receive payouts.
Checkout payloads
Create destination-charge Checkout sessions server-side so buyers cannot alter seller IDs or platform fees.
Order records
Turn signed `checkout.session.completed` events into paid-order records with idempotent event handling.
Buyer smoke path
1. Verify
Run the manifest check so the delivered files match the archive.
2. Test
Run the included tests for signature checks, readiness gates, destination payloads, and duplicate events.
3. Adapt
Replace the in-memory store with your database and configure your own Stripe account/webhook secrets.
4. Harden
Keep seller IDs, capability checks, platform fees, and checkout creation on the server.
