How to Add Stripe to a Lovable App
Lovable offers a chat-driven Stripe integration. Describe your payment requirements — subscription tiers, one-time checkout, pricing — and Lovable auto-generates the Edge Functions, database tables with RLS, and UI components. Store your Stripe Secret Key in Lovable Secrets, never in chat.
Why this matters
Monetization is what turns your Lovable prototype into a real business. Stripe is the most widely used payment processor for SaaS, and Lovable makes the integration almost entirely prompt-driven — you describe what you want and the platform generates the backend, database, and UI.
What's at stake
A misconfigured Stripe integration can silently fail, losing you revenue. Worse, exposing your Stripe Secret Key in frontend code gives attackers full access to your payment account — refunds, transfers, and customer data.
Step by step.
Connect your Lovable project to Supabase
Supabase is required for Stripe integration in Lovable. It handles secure payment processing, subscription management, webhook handling, customer data storage, and error handling.
Store your Stripe keys in Lovable Secrets
Add your Stripe Secret Key and Publishable Key through Lovable's "Add API Key" form in project settings. Never paste the Secret Key directly in the chat — even though Lovable warns you, the key may persist in chat history.
Describe your payment structure to Lovable
Be specific with your prompt. For subscriptions: "Add three subscription tiers: Free, Pro at $29/month, and Business at $79/month with Stripe checkout." For one-time payments: "Create a one-time checkout for my e-book at $29." Lovable auto-generates Edge Functions, database tables with RLS, and the checkout UI.
Configure Stripe webhooks (for subscriptions)
For subscription management and role-based access, Lovable uses Supabase Edge Functions to handle Stripe webhook events like payment_intent.succeeded and customer.subscription.created. Ask Lovable to set up webhooks if your payment structure requires them.
Deploy and test with Stripe Test Mode
Stripe integration does not work in Lovable preview mode — you must deploy. Use Stripe Test Mode with test card 4242 4242 4242 4242 (any future expiry, any CVC) to verify the full payment flow before going live.
Debug issues using three log sources
If payments fail, check: (1) Browser Console for frontend errors, (2) Supabase Logs > Edge Functions for webhook errors, and (3) Stripe Dashboard > Webhooks for data transmission issues. Use Lovable Plan Mode for follow-up debugging.
Verify your Lovable payment integration before going live
- Automated check that Stripe keys are not exposed in frontend code
- Webhook configuration verification for subscription management
- End-to-end payment flow testing guidance
Frequently asked questions.
Yes. Lovable supports both through its Stripe integration. Describe your requirements in a prompt — subscriptions with tiers, one-time checkouts, or both — and Lovable generates the complete payment flow including Edge Functions, database tables, and UI.
No. Stripe integration requires server-side processing that does not work in preview mode. You must deploy your app to test payments. Use Stripe Test Mode with the card number 4242 4242 4242 4242 for safe testing.
Rotate the key immediately. Go to your Stripe Dashboard, generate a new Secret Key, revoke the old one, and store the new key in Lovable Secrets. The old key may persist in your Lovable chat history.
No. Tell Lovable what events you need to handle (e.g., "Handle subscription created, updated, and canceled events from Stripe") and it generates the Supabase Edge Functions for you. For simple one-time payments without subscriptions, webhooks may not be needed.
