Per-client throttling limits are applied to clients that use API keys associated with Note that these limits can't be higher than the AWS throttling limits. YouĬan configure the same settings for all methods, or configure different throttle settings for each method. Per-API, per-stage throttling limits are applied at the API method level for a stage. For more information, see Amazon API Gateway quotas and important notes. To request an increase of account-level throttling limits per Region, contact the AWS Support Center. Limit can be increased upon request - higher limits are possible with APIs that have shorter timeouts and Per-account limits are applied to all APIs in an account in a specified Region. These limits are set by AWS and can't be changed by a customer. These limit settings exist to prevent your API-and your account-from being overwhelmed by too many requests. Request submissions based on specified requests rates and quotas.ĪWS throttling limits are applied across all accounts and clients in a region. Alternatively, you can enable usage plans to set throttles on client Performance across all APIs in your account. Upon catching suchĮxceptions, the client can resubmit the failed requests in a way that is rate limiting.Īs an API developer, you can set the target limits for individual API stages or methods to improve overall
Clients may receive 429 Too Many Requests error responses at this point. When request submissions exceed the steady-state request rate and burst limits, API Gateway begins to throttle In the token bucket algorithm, a burst can allow pre-defined overrun of those limits, but other factors canĪlso cause limits to be overrun in some cases.
Specifically, API Gateway examines the rate and a burst of request submissions against all APIs in your account, per Both throttles and quotas are applied on a best-effort basis and should be thought of as targets ratherĪPI Gateway throttles requests to your API using the token bucket algorithm, where a token counts for a request. You can configure throttling and quotas for your APIs to help protect them from being overwhelmed by too many
