# Render one catalogued Slack message

`GET /v1/admin/slack-preview-messages/{message_id}/render`

## Request

- Base URL: `https://api.patricia.app` (the document declares no server; this is the origin it was published from)
- URL: `https://api.patricia.app/v1/admin/slack-preview-messages/{message_id}/render`
- Auth: HTTP bearer

Builds the entry from its dummy data through the REAL production builder and returns the frames: the notification line, a plain-text transcript, the control labels, and the raw Block Kit. Read-only: no Slack call, no database write. Works for render-only entries too.

## Path parameters

- `message_id` string, required
