Attachment API Attributes

When you list or view messages, or other API calls with attachments, you will get either a single attachment or an array of attachments in the API response. The attachment attributes will be the same and outlined in this article.

Response Parameters
Parameter Type Description

filename String The Attachment Filename
size Integer Exact File Size in Bytes
size_human String Approximate, human friendly, file size (11.2 MB, 23.3 KB, ...)
content_type String The Content-Type
checksum String SHA-256 Checksum
crc32 String CRC32 Checksum
assembled Boolean True if the attachment has been assembled or not (when uploading multiple chunks)
virus_scan_required Boolean True if the attachment is required to be Virus Scanned.
virus_scanned Boolean True if the attachment has been Virus Scanned.
virus_scanned_at DateTime When the Virus Scanner last scanned this attachment.
content_blocked Boolean True if the attachment has been blocked (by the Virus Scanner or ActionScript).
content_blocked_message String If the attachment has been blocked, this will display the reason.
