Response Details

The md5checksum__v field is calculated on the latest version of the attachment. If an attachment is added which has the same MD5 checksum value as an existing attachment on a given document, the new attachment is not added.

On SUCCESS, the response lists the following metadata for the requested attachment:

Metadata Field	Description
`id`	ID of the attachment. This is set by the system.
`external_id__v`	The attachment’s external ID if provided in a Create Multiple Document Attachments request. The response excludes this attribute if the attachment has no external ID.
`filename__v`	File name of the attachment.
`format__v`	File format of the attachment.
`description__v`	Optional description added to the attachment. The response excludes this attribute if the attachment has no description.
`size__v`	File size of the attachment in bytes.
`md5checksum__v`	MD5 checksum value calculated for the attachment. To avoid creating identical versions, Vault assigns each version a checksum value.
`version__v`	Version of the attachment. Attachment versioning uses integer numbers beginning with 1 and incrementing sequentially (1, 2, 3,...). There is no concept of major or minor version numbers with attachments.
`created_by__v`	The ID of the User that created the attachment.
`created_date__v`	Date the attachment was created.
`versions`	List of links to previous versions of the attachment. Includes the `version__v` and `url` for the Retrieve Document Attachment Version Metadata endpoint to retrieve this attachment version.
