Stripe Checkout Not Working in Production in Lovable App
Stripe checkout works perfectly in test mode but fails when you switch to live/production keys. The checkout button does nothing, the Stripe form shows errors, or payments process but your app doesn't receive the confirmation.
Payment processing failures directly impact your revenue. Every failed checkout is a lost customer who may never return. This is the most business-critical bug your app can have.
Common symptoms include: the checkout redirect failing silently, the payment succeeding on Stripe's dashboard but the webhook not updating your app, or the live API key being rejected.
Error Messages You Might See
No such price: 'price_...'
Webhook signature verification failed
Your account cannot currently make live charges
Invalid API Key provided: sk_test_...
Common Causes
- Test keys in production — The app still uses sk_test_ and pk_test_ keys instead of sk_live_ and pk_live_ keys
- Webhook endpoint not updated — Webhooks are configured for your test endpoint but not the production URL
- Webhook secret mismatch — The webhook signing secret doesn't match between Stripe dashboard and your environment variables
- Products not created in live mode — Price IDs from test mode don't exist in live mode; you need to recreate products
- Account not fully activated — Your Stripe account hasn't completed the verification process required for live payments
How to Fix It
- Verify you're using live keys — Check that environment variables use sk_live_ and pk_live_ prefixed keys, not test keys
- Recreate products in live mode — Products and prices created in test mode don't carry over. Create them again in live mode and update your price IDs
- Configure live webhooks — In Stripe dashboard → Developers → Webhooks, add your production URL as a webhook endpoint for live events
- Update webhook signing secret — Copy the signing secret from the live webhook endpoint and update your environment variable
- Complete Stripe account activation — Go to Stripe dashboard and complete any pending verification steps required for live payments

Alvin Voo
I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.
Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
Why do test payments work but live payments don't?
Test and live mode are completely separate in Stripe. Products, prices, webhooks, and API keys are all different between modes. You need to set up everything again for live mode.
How do I test live payments without real charges?
You can't avoid real charges in live mode — that's the point. Test thoroughly in test mode first, then use small amounts ($0.50) for your first live test. You can refund test charges immediately.
