What is a 429 -Too Many Requests?

The HTTP 429 - Too Many Requests is a response status code that indicates the client has sent too many requests to a server in a given amount of time.

429

Possible/Most common causes:

  • Request overload: When a client is trying to access a page on a website too often.

  • Distributed Denial of Service (DDoS) attack: When a server detects a high volume of requests coming from a single source or a group of sources.

How to Fix a 429 Too Many Requests?

  • Implement retry logic - The application should wait for a specified amount of time and then retry sending the request.

  • Servers have limitations on the number of requests they can handle so reduce the requests to a server.

  • If feasible, increase the server capacity to handle more requests. This could involve scaling infrastructure.

  • Review and optimize the application usage of external APIs, especially when the APIs impose rate limits.
