Use this endpoint when you need to retrieve metadata or a download URL for a file attached to a specific email draft in AgentMail. Prefer this over generic file storage lookups when the attachment is associated with an AI agent's inbox draft workflow.
Side effects
- 404 Not Found — invalid inbox_id, draft_id, or attachment_id
- 401 Unauthorized — missing or invalid Bearer token
- Download URL already expired — expires_at has passed
- Attachment does not belong to the specified draft or inbox
- Malformed path parameters causing routing errors
