Send Message

Send a message in a conversation. The endpoint automatically detects the conversation platform type and routes the message appropriately.

Platform-specific behavior:

  • Email: Requires sender_id. Supports subject, cc, bcc, attachments, and is_html.
  • LinkedIn: Only requires message. Message is queued for delivery via LinkedIn. The message is queued for async delivery. A temporary message is created immediately for optimistic UI updates, and the actual delivery happens in the background.
