# Attachment Authorization

> **BETA**

Attachments require additional scopes to allow file handling and attachment.

In addition to the scopes described in the [Request Authorization](/developers/api/authorization/request-authorization/index.md), Attachments requires the following:

##### `scope` *(required)*

- **event_attachments** to allow attachments to be uploaded to the users calendar or file storage service and attached to the event.

Attachments also offers the following simplified scopes, to make it easier to authorize for common use cases:

- **read_write_with_attachments** to allow all requests mentioned in **read_only**, **write_only**, and **event_attachments** scopes.

- **write_only_with_attachments** to allow all requests mentioned in **write_only**, and **event_attachments** scopes.
