API Request Timeout - Endpoint Takes Too Long

API requests timeout while waiting for response. Frontend gets 'fetch timeout' error or 504 error.

The endpoint works but is slow. Same endpoint sometimes works, sometimes doesn't.

Error Messages You Might See

Error: fetch timeout after 30000ms 504 Gateway Timeout Fetch failed - no response from server Operation timeout
Error: fetch timeout after 30000ms504 Gateway TimeoutFetch failed - no response from serverOperation timeout

Common Causes

  1. Endpoint performs heavy computation without optimization
  2. Database query not optimized - missing indexes or fetching too much data
  3. External API calls not having timeouts or being slow
  4. Request waiting for previous long-running requests to complete
  5. Timeout set too low for legitimate request duration

How to Fix It

Set fetch timeout: fetch(url, { timeout: 30000 }) for 30 second timeout

Optimize queries: add database indexes, use pagination for large results

Add timeout to external calls: fetch(externalUrl, { timeout: 5000 })

Move long tasks to background jobs, return response immediately

Monitor endpoint: track execution time, profile bottlenecks

Frequently Asked Questions

What's a good timeout for API calls?

Client-side: 30s max. For database: 5-10s depending on complexity. External APIs: 10-15s

How do I handle slow endpoints?

1) Optimize the query/logic, 2) Use background jobs for long tasks, 3) Increase timeout, 4) Implement pagination

Should I retry on timeout?

Sometimes. For idempotent endpoints (GET, DELETE with same ID) yes. For POST/mutations, be careful of duplicates
