Checkout + Fulfillment Stack is a webhook tool product available on the Whop marketplace and launched in July 2026.

The glue between a sale and a delivered, licensed product. Checkout + Fulfillment Stack connects your payment processor to automatic file delivery and license issuance, with webhook handlers for common processors, an order-to-fulfillment flow, and email-delivery templates. What's inside: - Webhook handlers for common payment processors - Order-to-fulfillment automation flow - Auto license issuance on successful payment - Email-delivery templates (order confirmation + access details) - Failure/retry handling for missed webhooks - Setup + configuration documentation Who it's for: sellers who currently deliver products manually after a sale and want zero-touch fulfillment from payment to access. Prerequisites: a VPS or Docker-capable host, Docker + Docker Compose, API keys from your payment processor, an email-sending service (e.g. SMTP credentials), basic Linux comfort. Setup: ~45-75 min. Self-hosted only — expect €5-15/mo hosting. Single-business-use code license. 7-day refund if setup fails after following the guide and contacting support first.
