SellWell

A guided build to learn Stripe webhooks and background jobs with Inngest. New stores stay pending until an admin approves them. A cart with products from several sellers gets split into one order per seller at checkout.

• The Stripe webhook verifies the signature with constructEvent, then marks the orders paid or deletes them if checkout is cancelled.
• Clerk user events go to Inngest functions that keep the database in sync.
• Coupons can be restricted to new users or members (checked with Clerk has({ plan: 'plus' })).
• Uploading the first product image calls an OpenAI vision model to pre-fill the name and description.

The main flows work: store approval, Stripe checkout with webhook verification, and the Clerk-to-database sync through Inngest.
