## Permissions

Any user or [API key](https://developers.vtex.com/docs/guides/api-authentication-using-api-keys) must have at least one of the appropriate [License Manager resources](https://help.vtex.com/en/tutorial/license-manager-resources--3q6ztrC8YynQf6rdc6euk3) to be able to successfully run this request. Otherwise they will receive a status code `403` error. These are the applicable resources for this endpoint:

| **Product** | **Category** | **Resource** |
| --------------- | ----------------- | ----------------- |
| Catalog | Configuration | **CMS Management** |

There are no applicable [predefined roles](https://help.vtex.com/en/tutorial/predefined-roles--jGDurZKJHvHJS13LnO7Dy) for this resource list. You must [create a custom role](https://help.vtex.com/en/tutorial/roles--7HKK5Uau2H6wxE1rH5oRbc#creating-a-role) and add at least one of the resources above in order to use this endpoint. To learn more about machine authentication at VTEX, see [Authentication overview](https://developers.vtex.com/docs/guides/authentication).

>❗ To prevent integrations from having excessive permissions, consider the [best practices for managing API keys](https://help.vtex.com/en/tutorial/best-practices-api-keys--7b6nD1VMHa49aI5brlOvJm) when assigning License Manager roles to integrations.
