Creating an Excluded Request Throttling Configuration

Function

A request throttling policy controls the maximum number of times an API can be accessed within a specified period and the maximum numbers of times the API can be accessed by a tenant or an app within the same period.

If necessary, you can create an excluded request throttling configuration to specify the threshold of API calls for a specific app. For example, if you set the API call threshold for all apps to 500 calls/minute, you can specify the API call threshold of app 1 as 800 calls/minute.

You can add excluded apps or tenants to a request throttling policy.
