How to Build a Membership or Paywall in Replit

Build a membership paywall in Replit by combining Stripe payment with authentication and a database flag. When a user pays, Stripe sends a webhook to your app. The webhook handler marks the user as a paid member in your database. Protected routes check this flag and redirect non-members to the sales page. Claude writes the complete flow: Stripe checkout, webhook handler, member status update, and route protection.

How a Paywall Works Technically

A paywall is three things connected: a payment that creates a member record, an authentication system that identifies who is logged in, and route protection that checks the member record before allowing access. Strip away any of the three and the paywall breaks.

The sequence: User pays via Stripe. Stripe sends a webhook to your app. Your webhook handler creates or updates a user record in your database with paid_member: true. User logs in. Protected routes check paid_member status. If true, show content. If false, redirect to buy page.

What to Ask Claude

"Build a membership paywall system in my Replit app. When a user completes Stripe checkout using price ID [your price ID], the Stripe webhook at /webhook should find or create a user record in SQLite with their email and set paid_member to true. Protected routes at /members/* should require both authentication and paid_member status. Non-members should be redirected to /buy. After payment, redirect to /members/welcome."

Testing Your Paywall

Use Stripe's test mode with test card numbers (4242 4242 4242 4242) to test the complete flow without real money. Test both the happy path (successful payment, member access granted) and the failure path (declined card, access not granted). Ask Claude to show you the test card numbers and the curl command to test the webhook locally.

Frequently Asked Questions

How do I build a membership paywall in Replit?
Three components: Stripe payment that triggers a webhook, a webhook handler that sets a paid_member flag in your database, and route protection middleware that checks the flag before allowing access.
What is a Stripe webhook and why do I need it for a paywall?
A webhook is Stripe calling your app after a payment succeeds. You need it because Stripe processes payment on their servers -- your app does not know about it without the webhook notification.
How do I test my paywall without real payments?
Use Stripe test mode with test API keys and test card number 4242 4242 4242 4242. All test payments are free. Switch to live keys only when ready for real payments.
Can I offer both one-time purchases and subscriptions?
Yes -- Stripe supports both payment types. A one-time payment creates a permanent member flag. A subscription requires checking that the subscription is still active before granting access. Ask Claude to implement whichever model fits your offer.
How do I revoke member access?
Set paid_member to false in the database for the user. For subscriptions, Stripe sends a webhook when a subscription cancels or fails -- the webhook handler should update the database flag accordingly.
