🔧 Fix API Errors

API Not Working?
We Fix It

APIs are the backbone of your app — when they fail, everything breaks. We fix 500 errors, CORS issues, timeout problems, and broken integrations. Working code via GitHub PR within 48 hours.

Common API Symptoms

These are the API errors we fix most often.

API route returns 500 Internal Server Error
API route returns 404 even though the file exists
CORS error blocks requests from frontend to backend
Request times out after 30 seconds
API returns empty response body
PATCH and DELETE methods not allowed
Headers not accessible in API route
Environment variables undefined in API handler
WebSocket connections rejected by API server
File upload returns 413 Payload Too Large

Root Causes of API Failures

We find the actual cause — not just patch the error message.

1Unhandled Promise Rejections

API handlers catch errors silently or throw them without proper HTTP status codes — Next.js returns 500 for any unhandled error.

2Missing API Route Export

Handlers must export named functions (GET, POST, etc.) — missing exports cause silent 404 responses.

3CORS Preflight Misconfiguration

OPTIONS requests are not handled, causing browsers to block actual API requests with CORS errors.

4Request Body Parsing Mismatch

Request body format (JSON vs FormData vs URLSearchParams) does not match how the handler parses it.

5Response Content-Type Header Mismatch

API returns data in one format but sets a different Content-Type header, causing client-side parsing failures.
