# Create REST API access policy

Create an API access policy and map an authentication profile to restrict the authentication type for a REST API. For example, you can create an API access policy that allows only ID token authentication for a REST API.

## Before you begin

An authentication profile must be created. For more information, see [Create an authentication profile](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/create-authentication-profile.md).

Role required: api\_service\_admin, adaptive\_auth\_policy\_admin
