# Backend API Endpoints Documentation

Complete reference for all API endpoints in the Tour Builder Platform backend.

## Overview

- **Base URL**: `http://localhost:3000/api` for local development
- **Content-Type**: `application/json`
- **Authentication**: JWT Bearer Token (except public endpoints)
- **API Documentation UI**: `http://localhost:3000/api-docs` (Swagger, local development)

**Standard VM note:** the VM `dev_stage` backend listens on port `3000`, while
the frontend listens on `3001` and Apache serves the public domain on port `80`.
Use `http://127.0.0.1:3000/api/...` for direct VM backend checks. Protected
routes returning `401 Unauthorized` without JWT are healthy. See
[`deployment-vm.md`](../../documentation/deployment-vm.md).

## 8. Tour Pages

| GET | `/api/tour_pages` | List pages |
| GET | `/api/tour_pages/count` | Count pages |

| POST | `/api/tour_pages/:id/duplicate` | Duplicate a dev page as a new independent dev page |

**Permissions**: `CREATE_TOUR_PAGES`, `READ_TOUR_PAGES`, etc.

**Runtime Public Access**: GET endpoints accessible without auth in production mode.

### POST /api/tour_pages/reorder

Reorders pages for a project in the constructor environment.

**Auth:** Required

**Request:**

```json
{
  "data": {
    "projectId": "project-uuid",
    "environment": "dev",
    "orderedPageIds": ["page-uuid-1", "page-uuid-2", "page-uuid-3"]
  }
}
```

**Response:**

```json
[
  { "id": "page-uuid-1", "sort_order": 1 },
  { "id": "page-uuid-2", "sort_order": 2 },
  { "id": "page-uuid-3", "sort_order": 3 }
]
```

**Rules:**
- Only `environment: "dev"` is accepted. Stage and production are updated by
  publishing, not by direct reorder writes.
- `orderedPageIds` must include every page in the project/dev environment
  exactly once.
- The endpoint updates only `tour_pages.sort_order`; it does not alter
  `ui_schema_json`, slugs, backgrounds, media, navigation, or transitions.
- The visible stage order changes after Save to Stage. The visible production
  order changes after Publish.

**Validation failures:**
- Missing `projectId`
- Empty or invalid `orderedPageIds`
- Duplicate page IDs
- Missing pages from the ordered list
- Unknown page IDs or page IDs outside the project/environment
- Any environment other than `dev`

### POST /api/tour_pages/:id/duplicate

Duplicates a constructor/dev page into a new independent dev page.

**Auth:** Required

**Request:**

```json
{
  "data": {
    "projectId": "project-uuid",
    "environment": "dev",
    "name": "Lobby Copy",
    "slug": "lobby-copy"
  }
}
```

**Rules:**
- Only source pages in `environment: "dev"` can be duplicated.
- The requested target environment must also be `dev`.
- The source page must belong to the requested project.
- The new page is appended to constructor order with
  `sort_order = max(project dev sort_order) + 1`.
- The duplicate receives a new page ID, unique slug, and empty `source_key`.
- Page settings, background media fields, design dimensions, `requires_auth`,
  and `ui_schema_json` are copied.
- Inline `ui_schema_json.elements[]` IDs and nested gallery/carousel/info-panel
  item IDs are regenerated for independence.
- Asset URLs, transition URLs, and navigation `targetPageSlug` references are
  preserved.
- Reverse-video processing uses the existing `TourPagesService` path.

**Validation failures:**
- Invalid source page ID
- Source page not found
- Source page outside requested project
- Source or target environment other than `dev`

### POST /api/tour_pages

**Request:**
```json
{
  "data": {
    "projectId": "project-uuid",

    "requires_auth": false,
    "ui_schema_json": {
      "elements": [],
      "canvasSettings": {}
    }
  }
}
```

**ui_schema_json Structure:**
```json
{
  "elements": [
    {
      "id": "element-uuid",
      "type": "button",
      "props": {
        "x": 100,
        "y": 200,
        "width": 150,
        "height": 50,
        "label": "Click Me",
        "targetPageSlug": "next-page",
        "transitionVideo": "assets/transition.mp4"
      }

}
```

**Asset Types:** `image`, `video`, `audio`, `document`, `other`

**Type (Usage):** `background`, `transition`, `element`, `general`

**MIME Type Validation:**

The `mime_type` must match the `asset_type`:

| asset_type | Valid mime_type prefixes |
|------------|-------------------------|
| `image` | `image/` (jpeg, png, gif, webp, svg, etc.) |
| `video` | `video/` (mp4, webm, mov, etc.) |
| `audio` | `audio/` (mp3, wav, ogg, etc.) |

Other asset types (`document`, `other`, `file`) skip MIME validation.

## 12. Project Transition Settings

Environment-aware CSS transition settings for page navigation.

## 13. Global UI Controls

Configurable fullscreen, global sound, and offline buttons. Settings cascade
from global defaults to project/environment overrides and then page overrides.

### Global Defaults

| Method | Endpoint | Auth | Description |
|--------|----------|------|-------------|
| GET | `/api/global-ui-control-defaults` | None | Get singleton global UI-control defaults |
| GET | `/api/global-ui-control-defaults/:id` | None | Get defaults by ID |
| PUT | `/api/global-ui-control-defaults/:id` | JWT + UPDATE_PAGE_ELEMENTS | Update singleton defaults |

### Project/Environment Overrides

| Method | Endpoint | Auth | Description |
|--------|----------|------|-------------|
| GET | `/api/project-ui-control-settings/project/:projectId/env/production` | None or JWT for private production | Get production project overrides |
| GET | `/api/project-ui-control-settings/project/:projectId/env/dev` | JWT | Get dev project overrides |
| GET | `/api/project-ui-control-settings/project/:projectId/env/stage` | JWT | Get stage project overrides |
| PUT | `/api/project-ui-control-settings/project/:projectId/env/:environment` | JWT + UPDATE_PAGE_ELEMENTS | Upsert project overrides |
| DELETE | `/api/project-ui-control-settings/project/:projectId/env/:environment` | JWT + UPDATE_PAGE_ELEMENTS | Reset project overrides to global defaults |

`production` reads follow private-production presentation rules: public
presentations are public-readable, private presentations require JWT and an
allowlist/staff access check.
