Publishing - Postsiva

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

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
