How to Integrate Replit with Stripe

This tutorial shows how to connect Stripe to a Replit project so you can add secure payment processing to your app without leaving your workspace. Notes:

• You need a Replit account and a Stripe account to follow this tutorial. Sign up at stripe.com if you don't have one yet.
• Get your API keys from the Stripe Dashboard under Developers → API Keys. Store your secret key in the Replit Secrets pane as STRIPE_SECRET_KEY. Never paste it directly into your code.
• Use Stripe test mode and test card numbers while building. Switch to live keys only when your app is ready for real transactions.
  

1. Sign in at replit.com and open the project you want to add Stripe to, or click + Create Something New to start a fresh one.
2. In the Agent prompt field, describe the payment feature you want to build and mention Stripe directly - for example: Build a checkout page for NEPS Corp that accepts one-time payments for consulting services using Stripe. Click the Arrow button to run.
3. The Agent generates your project files and sets up the Stripe connection using your stored STRIPE_SECRET_KEY. Wait for the build to complete.
4. Test it in the Preview or Webview tab using a Stripe test card - for example, enter 4242 4242 4242 4242 as the card number and confirm the payment flow completes successfully.
5. Once testing is complete, replace your Stripe test keys with live keys in the Secrets pane. Your app is now ready to accept real payments.
