Stripe Connect Express makes it easy to launch a multi-seller platform, but real complexity shows up after go-live. Seller accounts and capabilities change over time, and payment flows that rely on static assumptions eventually break. This article walks through a practical approach to designing a Stripe Connect Express integration that survives those changes by treating Stripe as an event-driven system, using webhooks as the source of truth, modelling seller state internally, and making payment flows react to that state instead of relying on one-time checks.
