# Attachment API

The Attachment API provides endpoints that allow you to upload and query file attachments.

You can upload or retrieve a single file with each request.

The Attachment API respects any system limitations on uploaded files, such as maximum file size and allowed attachment types. You can control these settings using the properties **com.glide.attachment.max\_size**, 1024MB by default, and **glide.attachment.extensions**.

**Note:** The Attachment API accepts all Content-Type values \(\*/\*\). Specify the file content type when uploading an attachment. The content type is stored with file metadata allowing other tools to correctly identify and parse the file.

The following video provides more information on the Attachment API:

## Attachment API role requirements

To create attachments, the user record used to authenticate the HTTP request with ServiceNow must have any roles required to create Attachment \[sys\_attachment\] records. It must also have any roles required to read and write records on the target table, such as the itil role to add attachments to incident records.

By default there is no single role allowing a user to add attachments. You can create a role to explicitly allow adding attachments, then assign this role to the user account being used to make the request.

## Attachment - DELETE /now/attachment/\{sys\_id\}
