Identity-based policies for AWS End User Messaging

Supports identity-based policies: Yes

Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see Define custom IAM permissions with customer managed policies in the IAM User Guide.

AWS End User Messaging supports identity-based policies that use actions in both of its API namespaces: the sms-voice namespace for the SMS, MMS, voice, and RCS channels, and the social-messaging namespace for the WhatsApp channel.
