# Attachments

Attachments are how you share things in Protocol — they allow you to send all sorts of files to your contacts and groups. On this page, we'll dive into the different attachment endpoints you can use to manage attachments programmatically. We'll look at how to query, upload, update, and delete attachments. {{ className: 'lead' }}

## The attachment model

The attachment model contains all the information about the files you send to your contacts and groups, including the name, type, and size.

### Properties

  <Property name="id" type="string">
    Unique identifier for the attachment.
