Principal identifiers

When you refer to a principal in an Identity and Access Management (IAM) policy, you need to use the correct identifier for the principal. The format of the identifier depends on the type of principal you want to refer to and which version of the API you're using.

This page lists the identifier formats for each supported principal type for all API versions.

Note: For allow policies, you use the IAM v1 API. For deny policies, you use the IAM v2 API.

IAM v1 API

The following table describes the principal type identifiers for the IAM v1 API.
