# Reply Preview

`POST /api/app-auto-gtm/projects/{project_id}/reply-preview`

Throwaway auto-reply draft on a real case from this project, generated
with the caller's DRAFT instructions (the composer text, not a saved
field). Picks the most recent inbound reply (hot_lead preferred); a
project without replies falls back to a real lead + synthetic inbound
(``sample=true``). Deliberately uncached — see api/app_auto_gtm/reply_preview.py.

## Path parameters
