Stripe Integration

Implement Stripe payment processing for robust, PCI-compliant payment flows including…

A hands-on implementation guide for building robust, PCI-compliant Stripe payment flows end to end: hosted checkout, custom payment intents, subscriptions, customer portals, webhooks, and refunds. It pairs ready-to-use code patterns with the security disciplines, signature verification, idempotency, and never touching raw card data, that keep payments correct and money safe.

In a correct Stripe build, webhooks are the source of truth, not the redirect page. The skill creates sessions server-side, verifies every event signature, handles the critical lifecycle events one by one, and tests the full loop before a live key exists.

  1. Builds the payment flow on the right primitive: a hosted Checkout Session for speed, Payment Intents when the UI must be custom, Setup Intents to save a card without charging it.
  2. Creates sessions server-side with amounts in the smallest currency unit and metadata (order ID, user ID) linking every Stripe object back to your own database.
  3. Stands up the webhook endpoint: raw body in, signature verified against the endpoint secret, invalid payloads rejected with a 400 so Stripe retries.
  4. Handles the critical events one by one: a succeeded payment triggers fulfillment, a failed payment notifies the customer, a deleted subscription revokes access.
  5. Manages customers and payment methods through the API, with the customer portal wired in for self-serve subscription changes.
  6. Tests the whole loop in test mode with Stripe's card numbers (success, decline, 3D Secure, insufficient funds) before any live key is used.

Questions · still in the air

Catch what's on your mind.

the air is clear. nothing between you and the forge.
catch a spark: the forge will answer

  1. Is this my first-Stripe-project starting point, and does it cover both hosted and custom checkout?

    Yes on both. It is written for developers integrating Stripe for the first time and ships working patterns for hosted Checkout, custom Payment Intent flows, subscriptions with a customer billing portal, webhooks, and refunds, so you pick the surface that fits and follow the code.

  2. Stripe's own examples already exist. What is actually different here?

    The security discipline is wired into every pattern instead of left as a footnote: webhook signature verification, idempotent event processing so nothing runs twice, and never letting raw card data touch your servers. It also includes a test-card matrix covering edge cases like SCA challenges that most example code skips.

  3. Does it handle revenue analytics or syncing payment data to my database?

    No. It stops at the payment flow itself: checkout, subscriptions, webhooks, refunds, and disputes. Piping Stripe data into your database and keeping an MRR view consistent is a different problem, covered by the stripe-mrr-supabase-sync package.

  4. How is it delivered?

    By email right after purchase: ready to run, downloaded instantly, no setup wait.

  5. One-time or subscription?

    A one-time purchase; no subscription or hidden fees. VAT (20%) is included.

  6. Can I get a refund?

    As a digital product, it can’t be refunded once downloaded. That’s why we show exactly what’s inside and who it’s for, right here.
