Output shape

binary

The attachment file is stored as binary data in the property specified by the 'Output Binary Property' parameter (default: data). The operation does not return JSON data; the binary file can be used by subsequent nodes that accept binary input (e.g., Send Email, HTTP Request).

Examples

Example 1: Download an attachment by its ID

Set Download Mode to 'By Attachment ID', select the Account, Inbox, Conversation, and Attachment, and keep Output Binary Property as 'data'.

Example 2: Download an attachment via a public URL

Set Download Mode to 'By URL', paste the attachment URL into Attachment URL, optionally enable Allow External URLs if the URL points outside your Chat instance, and set Output Binary Property as desired.
