Xano + Stripe Integration Guide
Xano is an excellent backend for Stripe integration: its external API request module makes calling Stripe's API visual and debuggable, its webhook endpoint feature handles incoming Stripe events, and its database stores subscription state alongside your application data — all without a traditional server.
Why Xano + Stripe?
Xano's function stack can call Stripe's REST API directly using the External API Request module — no SDK needed. You can build a complete payment backend in Xano: create customers, create checkout sessions, retrieve subscription status, and update records when Stripe webhooks arrive. Because Xano's endpoints are standard REST, any frontend (WeWeb, FlutterFlow, or a custom app) can trigger them without modification.
Setting up payment flows
Store your Stripe secret key in Xano's environment variables. Create a Xano API endpoint /payments/create-session that: takes a price_id and user_id, looks up or creates a Stripe customer (using Xano's External API Request to POST to https://api.stripe.com/v1/customers), creates a Checkout session, and returns the session URL. Your frontend calls this endpoint and redirects to the Stripe-hosted checkout page. After payment, Stripe redirects to your success URL.
Webhook handling in Xano
Create a public Xano endpoint /webhooks/stripe that accepts POST requests. Register this URL in Stripe's webhook settings. In the Xano function stack, use the webhook's type field to branch: on checkout.session.completed, update the user's plan in the database; on customer.subscription.deleted, downgrade the user. Use Xano's signature verification step (using Stripe's webhook secret) to authenticate that events genuinely come from Stripe.
Real-world use cases
Xano + Stripe powers SaaS billing backends for platforms built on WeWeb, FlutterFlow, React, and Vue. App Studio's standard pattern: Xano manages the subscription state, Stripe manages the payment infrastructure, and the frontend simply shows the current plan status fetched from Xano. Customer portal URLs (generated from Xano by calling the Stripe Customer Portal API) are served as a simple Xano endpoint that the frontend redirects to.
Common pitfalls
Always verify Stripe webhook signatures in Xano — do not process events without validation. Xano's External API Request module returns raw responses; always add error handling for non-200 status codes from Stripe. Keep Stripe customer IDs in a dedicated column in your users table in Xano for fast lookups during webhook processing. Test every webhook event type in Stripe's CLI (stripe trigger checkout.session.completed) before going to production.
