Integrating Stripe Payments

Stripe payments integrate with Next.js and Convex through server-side actions that create Checkout Sessions and handle webhooks. Configure your Stripe API keys and webhook secrets in environment variables, then use Convex functions to initialize the Stripe client, manage customer creation, and process webhook events for subscription or one-time payments.

Stripe webhooks in Convex require configuring your webhook endpoint domain, listening for payment events, and synchronizing user state asynchronously. Proper timestamp unit conversion and error handling across installation and deployment phases ensure reliable lifecycle updates for subscriptions and charges.

Yes, Stripe hosted Checkout works with Convex and Next.js. This approach uses server-driven workflows to create Checkout Sessions, passing customer and pricing metadata from your Convex backend, then redirecting users to Stripe's hosted payment page and handling the return flow on a dedicated page.

Yes, Stripe integration requires creating products and prices in your Stripe dashboard and storing their IDs in environment variables. Your Convex functions reference these price IDs when creating Checkout Sessions for subscriptions or one-time payments.

Local testing uses Stripe's webhook secret and event simulation tools to trigger webhook handlers in your Convex functions. Testing phases validate that webhook events properly update user state and that async error handling works before deploying to production.

After payment completion, Stripe sends webhook events that Convex functions receive and process to update membership and billing status. Users are redirected to a return page in Next.js that displays payment confirmation and grants access based on subscription state.
