# Publish a marketplace demo

PATCH https://api.dsx-air.nvidia.com/api/v3/marketplace/demos/{id}/publish/
Content-Type: application/json

Immediately publishes the marketplace demo. Default `prefer_public` is `true` (globally visible). When `prefer_public` is `false`, send authoritative `allowed_orgs` as a UUID array for the restricted allow-list (distinct from gated `request-publish` string hints). Optional `justification` is stored for audit when provided. Set `publish_images` to `true` to publish org-owned images referenced by the demo so they reach the demo audience. Returns **400** when the demo is already published, has a pending first-publish request, when any referenced image needs publishing to reach the demo audience and `publish_images` is `false`, or when an image owned by another organization is not yet visible to the demo's target audience. `name`, `description`, `tags`, `documentation`, and `publisher` must be set on the marketplace demo before it can be published.

**Required scopes (any one):**

- `air:marketplace_demo_publish` (roles: `air_demo_manager`)

**Additional permissions:**

- Only members of the owning organization, Air admins, or SREs may perform this action on this marketplace demo.

Reference: https://docs.nvidia.com/dsx-air/api-reference/marketplace/api-v-3-marketplace-demos-publish-partial-update

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `id` (string, required) — A UUID string identifying this marketplace demo.

### Body (application/json)

This endpoint expects an object.

- `prefer_public` (boolean, optional, default: true) — Whether to publish as public (`true`, default) or restricted (`false`). When `false`, supply the authoritative `allowed_orgs`.
- `allowed_orgs` (list of string, optional) — Authoritative allow-list: orgs that may use the demo when `prefer_public` is `false`. The demo owning org is always included; `[]` is valid. Privileged endpoint only — not the gated `request-publish` string hint.
- `justification` (string, optional, default: ) — Optional text explaining who/why to share with.
- `publish_images` (boolean, optional, default: false) — When `true`, automatically publish org-owned images referenced by the demo so they reach the same audience as the demo. When `false` (default), the request is rejected with **400** if any referenced image needs to be published to reach the demo audience.
