# Attachment

<!-- WARNING: THIS FILE WAS AUTOGENERATED! DO NOT EDIT! -->

Messages of type `attachments` can display an image with a link to download/view an attachment or website. The attachment's **extension** and **size** can also be included.

The `ext` key displays a file type icon so users know what type of file the attachment is. Valid values are defined by the operating system.

The `size` key displays the size of the file. Set the `size` in bytes, for example 1 MB would be `"size": 1000000`.

For **style options**, see the [Full JSON schema](#full-json-schema).
