Rate Limit Exceeded - Too Many API Requests
API returns 429 Too Many Requests errors. Your app is making requests too quickly and hitting the rate limit.
Works initially then fails after rapid user actions.
Error Messages You Might See
Common Causes
- No throttling or debouncing on requests
- Multiple requests sent per keystroke (search, filter)
- Batch operations sending too many parallel requests
- Client-side retry loop without backoff
- Load testing or bot sending many requests
How to Fix It
Debounce requests: useDebounce(searchTerm, 500) for search/filter
Throttle API calls: max 1 request per X ms
Implement exponential backoff for retries: wait 1s, 2s, 4s, 8s...
Queue requests instead of parallel: process one at a time or in batches
Check API docs for rate limit: common is 100-1000 requests/minute

Get HelpFrequently Asked Questions
How do I know the rate limit?
Check API docs or response headers: X-RateLimit-Limit, X-RateLimit-Remaining
What's debounce vs throttle?
Debounce: waits for pause then fires (search). Throttle: fires max every X ms (scroll)
Should I implement retry logic?
Yes, with exponential backoff. Don't retry immediately - wait 1s then 2s then 4s
