You can configure a group rate limit policy that applies to all the managed APIs and custom APIs in a group. The group rate limit policy controls the number of times API consumers can invoke the APIs in a group during a designated time period.
If an API in the group has an API-specific policy that is different than the group policy,
API Manager
applies the API-specific policy to the API.
If all the APIs in your organization have a group policy that is different than the organizational policy,
API Manager
applies the group policy to all the APIs in the group.
If you add managed APIs that use anonymous authentication to a group, the group rate limit policy applies to all users for each anonymous API in the group.
You can assign rate limit tiers to specific users. User-specific tiers determine the access policies of the user that you assign them to and override the general group tier. For more information, see
Rate limit tiers.
