status
string
required
Lifecycle of an attachment. draft is a file that has been uploaded but nothing has been registered or submitted with it yet, and it is discarded at its expires_at. attached means at least one registration has cited it, so it is kept permanently and can no longer be deleted.
Possible values: draft, attached
download_url
string
required
Short-lived signed URL for downloading or previewing the attachment. Valid for 24 hours from when the resource was fetched; request a fresh resource to obtain a new URL after expiry. Do not cache beyond download_url_expires_at. Registration authorities (10DLC and toll-free carriers) retrieve evidence via a separate, longer-lived token; this URL is not that token.
preview_url
string
Optional signed URL for inline viewing on an isolated storage origin. Valid for one hour; fetch the attachment again to refresh it.
download_url_expires_at
string
required
When download_url expires. Both fields are always present; the server returns an error rather than omitting them.
expires_at
nullable string
required
When this attachment is discarded if nothing is registered or submitted with it. Null once its status is attached.
