# SIR Get Case Attachment Upload URL

Get an Amazon S3 pre-signed URL to upload an attachment to a case.

A pre-signed URL allows you to grant temporary access to users who don’t have permission to directly run AWS operations in your account. A pre-signed URL is signed with your credentials and can be used by any user.

For more information, refer to [Working with presigned URLs](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-presigned-url.html).
