Binding a Request Throttling Policy

Function

The request throttling policy bound to an API will control access of all users to the API.

If the number of API calls within a specified period reaches the limit, subsequent access will be rejected, protecting the backend API from abnormal traffic and ensuring stable service running.

This API is used to bind a request throttling policy to an API that has been published in an environment. You can bind different request throttling policies to an API in different environments, but can bind only one request throttling policy to the API in each environment.
