Everything You Need for YouTube Publishing
Skip YouTube's complex upload flow. PostPeer gives you a single endpoint for video publishing with full metadata control.
Video Uploads
Upload videos from a public URL or use PostPeer's media upload flow for local files. PostPeer handles YouTube's chunked upload process.
Title & Description
Set video title and tags through platformSpecificData, and include the video description in your post content. Full control over metadata.
Privacy Settings
Publish as public, unlisted, or private. Change visibility settings as part of your posting workflow.
Tags & Categories
Add tags and select YouTube categories to improve discoverability. All settable via the API.
Scheduled Publishing
Schedule videos for future publication. PostPeer uploads scheduled videos privately and changes them to the requested visibility at publish time.
Cross-Post to Shorts & Other Platforms
Upload a video to YouTube and simultaneously post to TikTok, Instagram Reels, and more with one request.
