# DescribeAttachment


Returns the attachment that has the specified ID. Attachments can include screenshots, error logs, or other files that describe your issue. Attachment IDs are generated by the case management system when you add an attachment to a case or case communication. Attachment IDs are returned in the [AttachmentDetails](API_AttachmentDetails.md) objects that are returned by the [DescribeCommunications](API_DescribeCommunications.md) operation.

**Note**  
You must have a Business, Enterprise On-Ramp, or Enterprise Support plan to use the AWS Support API. 
If you call the AWS Support API from an account that doesn't have a Business, Enterprise On-Ramp, or Enterprise Support plan, the `SubscriptionRequiredException` error message appears. For information about changing your support plan, see [AWS Support](http://aws.amazon.com/premiumsupport/).
