# Publishing

> Publish text, image, carousel, and video to multiple social platforms in one API call.

Publish once, fan out to every connected network in the workspace.

## Post types

| Type     | Endpoint                      | Platforms (typical)                               |
| -------- | ----------------------------- | ------------------------------------------------- |
| Text     | `POST /unified/post/text`     | LinkedIn, Facebook, Threads, Bluesky              |
| Image    | `POST /unified/post/image`    | All eight + media-required networks               |
| Carousel | `POST /unified/post/carousel` | LinkedIn, Instagram, Facebook, TikTok, …          |
| Video    | `POST /unified/post/video`    | LinkedIn, Facebook, Instagram, TikTok, YouTube, … |

## Multi-platform example

```bash theme={null}
curl -X POST "https://backend.postsiva.com/unified/post/text" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: psk_live_YOUR_KEY" \
  -d '{
    "platforms": ["linkedin", "threads", "bluesky"],
    "default_text": "Shipping our latest update."
  }'
```

Each platform returns its own result. One failure does not roll back the others.

## Destination controls

* **LinkedIn** — personal profile and/or org pages (`linkedin_page_ids`)
* **Facebook** — Pages (`facebook_page_ids`)
* **Pinterest** — board (`board_id`)
* **YouTube** — title + description required for video
* **TikTok** — privacy level

Full field reference: [Posting parameters](/apis/posting-parameters).

## Media first

Upload once, reuse `media_id` across platforms:

1. [Upload media](/apis/media)
2. Pass `default_image_id` / video id on the post body
