Stripe Test vs Live Mode Confusion
Test payments work but production payments fail. Using test keys in production or live keys in development. Webhooks not firing in right environment. Keys mixed up causing transaction failures.
Stripe has separate test and live environments with different keys. Mixing keys between environments breaks payment flow.
Error Messages You Might See
Invalid API Key provided
Authentication required
Key error: test key used in production
Common Causes
- Using test keys in production API calls
- Using live keys in development (risky!)
- Environment variables not switched between dev/prod
- Test webhook secret used with live key
- Not checking API in right mode in Stripe dashboard
How to Fix It
Use environment-specific keys:
// .env.development
VITE_STRIPE_PUBLISHABLE_KEY=pk_test_...
// .env.production
VITE_STRIPE_PUBLISHABLE_KEY=pk_live_...Always verify mode in Stripe dashboard toggle. Use test cards for development: 4242 4242 4242 4242.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

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.
