Postifys Docs
Developer documentation for Postifys: getting started, authentication, and creating social posts through the publishing API and n8n.
Quick answer: Create a Postifys account, connect a social destination, generate an API key in Settings, then publish with platform endpoints such as
POST /api/facebook/post using Authorization: Bearer YOUR_API_KEY.Authentication
API keys, Bearer / X-API-Key headers, key test endpoint, session vs key access.

Supported destinations
- Facebook Pages - feed, image, Reel
- Instagram professional - image, Reel/video
- YouTube channels - video upload
- Pinterest boards - image/video Pins (write access dependent on approval)
- LinkedIn member profiles - text, image, video, link (not Company Pages currently)
- TikTok creators - video upload to creator inbox (not Direct Post)
Honest limits: Endpoints remain platform-specific. Unified auth does not mean identical payloads. TikTok currently uses creator-inbox delivery unless Direct Post is separately approved.
