Common Issues
general
Third-Party Integration Not Working (APIs, Webhooks, OAuth)
Your app integrates with a third-party service (Google, Stripe, Twilio, OpenAI, etc.) and the integration stopped working or never worked properly. API calls fail, webhooks don't fire, or OAuth login redirects go nowhere.
Common Causes
- API keys expired, revoked, or not set in production
- Webhook URL points to localhost or an old deployment URL
- OAuth redirect URIs don't match the actual app URL
- Rate limits hit — the API is blocking requests because you're making too many
- API version changed and the integration code uses an outdated version
How to Fix It
- Check the third-party service's dashboard for error logs or failed requests
- Verify all API keys are current and set in your production environment
- Update webhook URLs to point to your production domain
- Check OAuth redirect URIs in the third-party service's settings
- Test the API calls directly (using Postman or curl) to isolate the issue

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.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Get HelpFrequently Asked Questions
The integration worked before. Why did it stop?
API keys might have expired, the service might have updated their API version, or your webhook URL might have changed after a redeployment.
Can a developer set up the integration properly?
Yes. A developer can debug the failing integration, update API configurations, and ensure everything is properly connected.
