About

The HTTP 429 Too Many Requests client error response status code indicates the client has stent too many requests in a given amount of time; this mechanism of asking the client to show down the rate of requests is commonly called “rate-limiting ”1.

Usages

  • A Retry-After header may be included to this response to indicate how long a client should wait before making the request again
  • Rate limiting implementations vary; restrictions may be server -wide or per resource ; typically, rate-limiting restrictions are based on a client’s IP but can be specific to users or authorised applications if requests are authenticated or contain a cookie
