Using Service-Linked Roles for User Notifications
AWS User Notifications uses AWS Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to User Notifications. Service-linked roles are predefined by User Notifications and include all the permissions that the service requires to call other AWS services on your behalf.
A service-linked role streamlines setting up User Notifications because you don’t have to manually add the necessary permissions. User Notifications defines the permissions of its service-linked roles. Unless defined otherwise, only User Notifications can assume its roles. The defined permissions include the trust policy and the permissions policy. That permissions policy can't be attached to any other IAM entity.
For information about other services that support service-linked roles, see AWS Services That Work with IAM and look for the services that have Yes in the Service-Linked Role column. Choose a Yes with a link to view the service-linked role documentation for that service.
