  • Comment (required) — Reply body content.
  • Body Type — HTML by default, or plain text.
  • Save to Draft — Save the reply as a draft instead of sending it immediately; defaults to false.
  • Add Attachment — Attach a binary file from the incoming item; defaults to false. Set Binary Field Name to the incoming item's binary property name, which defaults to data.
  • Inline Images — For HTML replies, map incoming binary properties to content IDs and reference them in the body with cid: URLs.
  • Auto-Embed Image URLs — For HTML replies, fetch public image URLs found in HTML image tags and include them as inline attachments; defaults to false.
