How to Add Stripe to a Replit App
Replit launched one-click Stripe integration in November 2025. Set it up with a single Agent prompt like "Add Stripe payments to my app with monthly subscription at $29/month." Replit generates checkout, webhook handlers, and real-time subscription sync to the database. Test in sandbox before going live.
Why this matters
Replit made Stripe integration easier than any other platform. Before November 2025, adding payments required manual webhook configuration and database schema setup. Now a single prompt handles everything — checkout, webhooks, subscription tracking, and database sync.
What's at stake
Even with one-click setup, your Stripe Secret Key must be stored in Replit Secrets, not in code. Public Repls with hardcoded Stripe keys expose your entire payment account. And skipping the sandbox test means your first real customer could hit a broken checkout.
Step by step.
Store your Stripe keys in Replit Secrets
Go to Tools > Secrets and add STRIPE_SECRET_KEY and STRIPE_PUBLISHABLE_KEY. Since December 2025, deployment secrets automatically sync with workspace secrets. Never hardcode keys in your code files.
Prompt the Agent to add Stripe
Use a single, specific prompt: "Add Stripe payments to my app with monthly subscription at $29/month. Include a pricing page, checkout flow, and restrict /pro features to paying users." The Agent generates everything — checkout, webhooks, database schema, and subscription status checks.
Review the generated payment code
Check that the Agent stored the Stripe Secret Key correctly (using process.env.STRIPE_SECRET_KEY, not hardcoded). Verify webhook endpoints validate the Stripe signature. Confirm subscription status is stored in the database.
Test in Stripe sandbox
Replit supports Stripe sandbox testing. Use test card 4242 4242 4242 4242 with any future expiry and any CVC. Complete a full checkout, verify the subscription appears in your database, and test cancellation.
Switch to live mode and deploy
Once sandbox testing passes, replace test keys with live Stripe keys in Replit Secrets. Deploy your app using Autoscale deployment for production. Monitor the first few real transactions in the Stripe Dashboard.

Frequently asked questions.
November 2025. Before that, adding Stripe to a Replit app required manually configuring webhooks, database schemas, and checkout flows. Now a single Agent prompt handles the entire setup.
Yes. Specify what you need in your prompt. For one-time payments: "Add Stripe checkout for a one-time purchase at $49." For subscriptions: "Add monthly subscription at $29/month." You can combine both in one app.
No. Replit does not require revenue sharing. You use your own Stripe account and keep 100% of revenue minus Stripe processing fees (2.9% + $0.30 per transaction for US cards).
Test in Stripe sandbox first — never go live without testing. If the checkout fails, check browser console logs, server logs in the Replit console, and the Stripe Dashboard webhook logs. Ask the Agent to fix specific errors.
