# Why do I get 429 response code error in your API?

"429" response code means too many requests in all TrackingMore API versions: V2, V3 & V4. 

When **429** error turns out, your application should not send any further requests and wait **120 secs**.

You are limited to only 3 or 10 requests/sec per API per account. Practically, this means you must (when possible) authenticate users so that limits are well outside the reach of a given user.
