FAQ
Can you fix CORS errors and Authentication (JWT) issues?
Yes, absolutely. CORS (Cross-Origin Resource Sharing) and JWT/OAuth2 authentication failures are the most common issues I resolve. I will ensure your backend is configured correctly to allow secure requests from your frontend (React, Next.js, etc.) and that your tokens are being generated and verifi
Which 3rd-party APIs can you integrate?
I can integrate almost any REST API. This includes payment gateways (Stripe, PayPal), social media APIs, Google Maps, Twilio (SMS), AWS S3, and various CRM or shipping APIs. If you have the API documentation, I can make it work seamlessly with your Node.js backend.
Do I need to provide the source code or server access?
To fix bugs or integrate APIs, I will need access to your Node.js/Express source code. You can provide this via a Zip file or by adding me as a collaborator on your GitHub/GitLab repository for deployment-related issues.
Will you provide documentation for the new API endpoints?
Yes! For every API integration or custom development project, I provide a free Postman Collection. This allows you to test all endpoints easily. I also ensure my code is well-commented and clean, making it easy for you or your team to maintain in the future.
