# Role Assignment API

API Reference for Role Assignment

> **Terminology Update:** We have streamlined our naming conventions to improve clarity. The term **Authorization** has been replaced with **Role Assignment**. To avoid breaking changes the APIs still make use of the old term. Both terms refer to the same underlying functionality.

## Update Application

## Activate Role Assignment

Activate Role Assignment: Note: Authorization in this context refers to role assignments, not to OAuth authorization. [Activate Authorization](/content/docs/reference/api/authorization/zitadel.authorization.v2.AuthorizationService.ActivateAuthorization) activates an existing but inactive authorization.
