tflint (REST): aws_apigateway_stage_throttling_rule. It is supported by API Gateway using API Keys but the customer has not implemented API keys for each of their customers and is looking for other options leveraging information in the API request/header. Amazon API Gateway supports defining default limits for an API to prevent it from being overwhelmed by too many requests. terraform aws api gateway configure method throttling per each api key. You can even test an API with your API Key. I set Default Method Throttling Rate to 1 request per second, and Burst to 1 request. For more information, see Amazon API Gateway quotas and important notes. Amazon API Gateway usage plans now allow you to throttle requests for individual methods at different rates by configuring method level throttling. In the token bucket algorithm, a burst can allow pre-defined overrun of those limits, but other factors can . at api key level In cases when we need to configure throttling and quotas etc., at the api key level, we need to create a usage plan for the api key and link the two. API Gateway provides a feature to limit the number of requests a client can make per second (rate) and per day/week/month (quota). quota_settings - Quota of the usage plan. Per-API, per-stage throttling limits are applied at the API method level for a stage. In addition to all arguments above, the following attributes are exported: name - Name of the usage plan. So you have to check throttling setup for that specific path (not for the entire stage). Rate limiting is very useful to protect your system from resource starvation caused by a client flooding your system with requests. Go ahead and change the settings by clicking on Edit .

With method level throttling now included in usage plans, you can configure throttling (rate . It says default method throttling. But you are setting the throttling for one specific resource and method /v1/test/GET. Customer that is looking to implement throttling on their APIs exposed via API Gateway and would like to know if that throttling occurs before invocation of a Lambda custom authorizer, which they are also implementing. What is AWS API throttling rate exceeded error? Throttling is an important concept when designing resilient systems. API Gateway throttles requests to your API using the token bucket algorithm, where a token counts for a request. Customer is looking to implement API throttling to their APIs exposed via API Gateway. Usage plans allow you to grant customers access to selected APIs at specific request rates and quotas. Specifically, API Gateway examines the rate and a burst of request submissions against all APIs in your account, per Region. Setting the burst and rate to 1,1 respectively will allow you to see throttling in action. I'm trying to enable API Gateway throttling, but it's not working as expected. 1 Answer.

For a stage belonging to an API in AWS API Gateway I have the option to limit Default Method Throttling. Customized rate limiting for API Gateway by path parameter, query parameter, and more. If you need to integrate external tools, AWS API Gateway provides an extra security and authentication layer for front-end web services. tflint (HTTP): aws_apigatewayv2_stage_throttling_rule. Regardless if you're trying to design a system to protect . Client API Throttling in API Gateway. throttle_settings - Throttling limits of the usage plan. api_stages - Associated API stages of the usage plan. You are looking at the stage-level throttling. In fact, this is regardless of whether the calls came from an application, the AWS CLI, or the AWS Management Console. It is a great tool for web services development.
