# Export Image Pptx

`POST /api/v1/slides/export-image-pptx/{project_id}`

## Request

- Base URL: `https://api.slidemaster.tw` (the document declares no server; this is the origin it was published from)
- URL: `https://api.slidemaster.tw/api/v1/slides/export-image-pptx/{project_id}`
- Auth: none declared

Build a downloadable .pptx from a project's rendered slide images.

Behaviour:
  - Pulls slides ordered by `projects.slide_order` (matches user's view).
    Falls back to slide_number sort if no arrangement exists.
  - Skips slides without `image_path`. If ALL slides are missing images,
    returns 404 (rather than emitting a 0-slide pptx).
  - Writes output to gs://slidemaster-render-outputs/{project_id}/export/image_export.pptx
  - Returns a 1-hour signed URL with the project title as filename.

## Path parameters

- `project_id` string, required

## Headers

- `Authorization` string, nullable

## Response `200`

Successful Response

- object

## Other responses

- `422`: Validation Error
