Welcome to the IAM Identity Center API Reference

With AWS IAM Identity Center, you can manage sign-in security for your workforce identities, also known as workforce users. IAM Identity Center provides one place where you can create or connect workforce users and manage their access centrally across all their AWS accounts and applications. IAM Identity Center is the recommended approach for workforce authentication and authorization in AWS, for organizations of any size and type.

This guide provides information about single sign-on operations that you can use to manage access to AWS accounts. For information about IAM Identity Center features, see the IAM Identity Center User Guide.

Many operations in the IAM Identity Center APIs rely on identifiers for users and groups, known as principals. For more information about how to work with principals and principal IDs in IAM Identity Center, see the Identity Store API Reference.
