WeWeb + Stripe Integration Guide
Adding payments to a WeWeb app requires connecting to Stripe — the gold standard for online payments. Because WeWeb is a frontend tool, payment logic must run through a backend (Supabase edge functions, Xano, or a Vercel serverless function) that securely creates Stripe sessions and handles webhook events.
Why WeWeb + Stripe?
Stripe handles the entire payment lifecycle — one-time purchases, subscriptions, usage-based billing, invoices, and the customer portal — so your WeWeb app only needs to trigger the right Stripe flows at the right moments. Stripe's SDKs and webhook system are mature and battle-tested at scale. For no-code builders, this is the most reliable path to monetisation without building a custom payment system.
Setting up the integration
Never call Stripe's secret API key from WeWeb directly — browsers expose your source code. Instead, create a serverless function (Supabase edge function, Xano endpoint, or Vercel function) that accepts a product ID and user ID, creates a Stripe Checkout session, and returns the session URL. In WeWeb, add a button action that calls this endpoint and then navigates to the returned URL. Stripe handles the payment form on their hosted page.
Subscription and billing flow
For subscriptions, create Stripe Products and Prices in the Stripe dashboard. Your backend function creates a Checkout session with mode: "subscription" and the price ID. After payment, Stripe fires a checkout.session.completed webhook — your backend handles this to update the user's subscription status in your database. WeWeb reads this status to gate premium features. For cancellations and upgrades, generate a Stripe Customer Portal URL from your backend and redirect the user.
Real-world use cases
WeWeb + Stripe powers SaaS subscription apps, one-time product sales, course platforms, and marketplace payouts. A common App Studio pattern: WeWeb frontend shows pricing plans, a Supabase edge function creates the Stripe session, Stripe processes payment, a webhook updates the user's plan in Supabase, and WeWeb re-fetches the user profile to unlock premium UI sections.
Common pitfalls
Never expose your Stripe secret key in WeWeb. Always use webhook signatures to verify Stripe events — do not trust query params on your success URL to confirm payment. Handle idempotency: Stripe can fire webhooks more than once, so your backend should check if the subscription is already active before updating the database. Use Stripe's test mode and test card numbers extensively before going live.
