HTTP 429 Too Many Requests Error - Meaning & Fix

The HTTP 429 Too Many Requests status code means you've made too many requests in a short time. A Retry-After header may specify how long to wait before attempting another request. Please adhere to the indicated wait time.

Main causes

  • Excessive request rate by a single user or API client within a designated timeframe.

  • Shared IP address making numerous concurrent requests, triggering rate limits.

  • Automated scripts or bots making frequent and repetitive requests to the server.

  • Misconfigured client application repeatedly attempting to connect or synchronize data too quickly.

# Request example 
curl -X POST https://sandbox.oxylabs.io/ -H 'Accept: application/xml;q=0.9' -H 'Accept-Encoding: compress' -H 'User-Agent: Mozilla/5.0'

Common fixes

  • Identify the failed dependency: Check the logs or error messages to determine which specific action or resource the request was dependent on that caused the failure.

  • Resolve the underlying issue: Address the root cause of the failure of the dependent action. This might involve fixing a bug, resolving a server issue, or ensuring that a necessary service is running.

  • Retry the request: Once the dependency issue has been resolved, attempt the original request again to see if the error persists.

  • Review and optimize dependencies: Analyze the dependencies of your requests to minimize coupling and reduce
