# API Reference - E2E Documentation

## Overview

The Tour Builder Platform exposes a RESTful API built with Express.js. All endpoints follow consistent patterns for CRUD operations, authentication, and response formats.

**Base URL:** `http://localhost:3000/api` for local development.

**Standard VM:** Apache serves the public domain on port `80`, the frontend
PM2 app listens on `3001`, and the backend PM2 app listens on `3000` with
`NODE_ENV=dev_stage`. Use `http://127.0.0.1:3000/api/...` for direct VM backend
checks, or `http://tbp.flatlogic.app/api/...` through Apache/Cloudflare. See
[deployment-vm.md](deployment-vm.md).

## Authentication

### JWT Bearer Token

Most endpoints require JWT authentication via the Authorization header:

```
Authorization: Bearer <token>
```

**Token Details:**
- Expiration: 6 hours
- Payload: `{ id, email, name }`
- Obtained via `/api/auth/signin/local` or OAuth callbacks

### Public Endpoints (No Auth Required)

- `GET /api/health`
- `POST /api/auth/signin/local`
- `POST /api/auth/send-password-reset-email`
- `PUT /api/auth/password-reset`
- `PUT /api/auth/verify-email`
- `GET /api/auth/email-configured`
- `GET /api/auth/signin/google`
- `GET /api/auth/signin/microsoft`
- `GET /api/runtime-context`

### Runtime Public Access

In **production** runtime mode only, certain GET endpoints allow unauthenticated read access (stage requires authentication):
- `GET /api/projects`
- `GET /api/tour_pages`
- `GET /api/project_audio_tracks`
- `GET /api/global-ui-control-defaults`
- `GET /api/project-ui-control-settings/project/:projectId/env/production`

**Note:** The `X-Runtime-Environment` header must be set to `production` for public access. Stage environment (`stage`) requires JWT authentication as it serves as a workspace for review.

## Standard Response Formats

### Success Responses

**Single Entity:**
```json
{
  "id": "uuid-here",
  "name": "Entity Name",
  "createdAt": "2024-01-01T00:00:00.000Z",

---

## Rate Limiting

The API uses rate limiting to prevent abuse. Rate limits are applied per IP address, and rate limit headers are returned with each response:

| Header | Description |
|--------|-------------|
| `X-RateLimit-Limit` | Maximum requests allowed per window |
| `X-RateLimit-Remaining` | Remaining requests in current window |
| `X-RateLimit-Reset` | ISO timestamp when the window resets |
| `Retry-After` | Seconds until you can retry (when limited) |

### Rate Limit Configuration

| Limiter | Window | Max Requests | Endpoints |
|---------|--------|--------------|-----------|
| **Auth** | 15 minutes | 10 | `/api/auth/signin/*` |
| **Password Reset** | 1 hour | 5 | `/api/auth/send-password-reset-email` |
| **API** | 1 minute | 100 | General API endpoints |
| **Upload** | 1 minute | 10 | `/api/file/upload*` |
| **Download** | 1 minute | 200 | `/api/file/download`, `/api/file/presign` |
| **Search** | 1 minute | 30 | `/api/search` |

**Note:** Rate limiting is skipped for localhost (`127.0.0.1`, `::1`) in development mode.

**Note:** This is part of the dev → stage → production workflow. Content is edited in `dev` (Constructor), previewed in `stage`, then published to `production`. Page elements, navigation, and transitions are stored in `tour_pages.ui_schema_json` and copied with pages.

## Tour Pages Endpoints

### POST /api/tour_pages

Create a tour page.

**Auth:** Required

**Request:**
```json
{
  "data": {
    "title": "Home Page",
    "slug": "home",
    "sort_order": 0,
    "projectId": "project-uuid",
    "environment": "dev",
    "background_image_url": "https://...",
    "background_video_url": "https://...",
    "ui_schema_json": {}
  }
}
```

### GET /api/tour_pages

List tour pages.

**Auth:** Optional (runtime public mode)

**Query Parameters:**
- `projectId` - Filter by project
- `environment` - Filter by environment

### GET /api/tour_pages/:id

Get tour page by ID.

**Includes:** project

**Note:** Page elements are stored directly in the `ui_schema_json` field.

### PUT /api/tour_pages/:id

Update tour page.

**Auth:** Required

### POST /api/tour_pages/reorder

Update page order within a project/environment without touching page content.

**Auth:** Required

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

**Behavior:**
- Reordering is allowed only in `dev`.
- `orderedPageIds` must contain every dev page in that project exactly once.
- Duplicate IDs, missing IDs, IDs from another project, and unknown IDs are
  rejected.
- The backend updates only `sort_order`; page content, slugs, navigation links,
  and media fields are not changed.
- Stage receives the new order after `POST /api/publish/save-to-stage`.
- Production receives the new order after `POST /api/publish`.

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

**Errors:**
| Status | Reason |
|--------|--------|
| 400 | Missing `projectId`, invalid `orderedPageIds`, duplicate/missing pages, or `environment` other than `dev` |
| 403 | Authenticated user is not allowed to update pages in the project |

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

Duplicate a dev tour page into a new independent dev page.

**Auth:** Required

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

**Behavior:**
- Only dev pages can be duplicated. Stage and production are updated through
  Save to Stage and Publish.
- The duplicate receives a new page ID, unique slug, blank `source_key`, and
  `sort_order = max(project dev sort_order) + 1`.
- Page media/settings fields and `ui_schema_json` are copied from the source
  page.
- Inline element IDs and nested item IDs in `ui_schema_json` are regenerated so
  the new page can be edited independently.
- Asset URLs, transition URLs, and navigation `targetPageSlug` values are
  preserved.
- Existing reverse-video processing still runs through `TourPagesService`, so
  transition reverse URLs are handled consistently with normal page save/create.

**Response:** Created tour page record.

**Errors:**
| Status | Reason |
|--------|--------|
| 400 | Missing source page, source page outside project, or non-dev source/target environment |
| 403 | Authenticated user is not allowed to create/update pages in the project |

### DELETE /api/tour_pages/:id

Delete tour page.

**Auth:** Required

**Constructor behavior:** the constructor uses this same endpoint for the active
dev page after showing a confirmation modal. After deletion it reloads page data
and selects the next page in presentation order when available.

### POST /api/publish/save-to-stage

Copy `dev` content to `stage` for preview. See [Projects Endpoints](#post-apipublishsave-to-stage).

### POST /api/publish (or POST /api/publish/publish)

Publish project from `stage` to `production` environment. Both endpoints are aliases and perform the same action.

**Auth:** Required

**Request:**
```json
{
  "projectId": "project-uuid",
  "title": "v1.0 Release",
  "description": "Initial production release"
}
```

**Response:**
```json

## Element Type Defaults Endpoints

Global platform-wide default settings for each element type. These are the source of truth that get snapshotted to `project_element_defaults` when a project is created.

**Alias:** `/api/ui-elements` routes to the same endpoints as `/api/element-type-defaults`.

**Note:** The Constructor page uses `project_element_defaults` (not this endpoint) to fetch element defaults for the current project. This endpoint is for platform-wide administration of default settings.

### GET /api/element-type-defaults

List all element type defaults.

**Auth:** Required

**Response:**
```json
{
  "rows": [
    {
      "id": "uuid",
      "element_type": "navigation_next",
      "name": "Navigation: Forward",
      "sort_order": 1,
      "is_active": true,
      "default_settings_json": {
        "width": "60px",
        "height": "60px",
        "opacity": 1
      }
    }
  ],
  "count": 11
}
```

### GET /api/element-type-defaults/:id

Get element type default by ID.

**Auth:** Required

### PUT /api/element-type-defaults/:id

      "height": "80px"
    }
  }
}
```

---

## Project Element Defaults Endpoints

Project-specific default settings for UI elements. These are automatically snapshotted from global defaults (`element_type_defaults`) when a project is created. The Constructor page uses this endpoint to fetch element defaults for the current project.

**Three-Tier Element Defaults Hierarchy:**
```
element_type_defaults (global) → project_element_defaults (project) → tour_pages.ui_schema_json (instance)
```

### GET /api/project-element-defaults
