In depth: How the YouTube API works on SocialAPI.ai

Read, reply to, and moderate comments on your YouTube channel, and publish videos with full metadata control. SocialAPI.ai handles the YouTube Data API quotas, the resumable upload protocol, and Google OAuth token refresh so you can ship features instead of plumbing.

Comment management

Read all comments across your videos, reply to viewers, hide inappropriate comments for review, and delete them permanently. YouTube comments flow through the same unified inbox endpoints you already use for every other platform.

Video publishing with full metadata

Upload videos through the unified publishing endpoint with full control over title, description, tags, category, language, visibility, scheduled publish time, and subscriber notification. SocialAPI.ai handles YouTube's resumable upload protocol and processing status tracking.

Post updates and lifecycle

Update video metadata (title, description, tags, privacy) after publishing, or delete videos entirely. The video file itself cannot be replaced (a YouTube platform limit), but everything else is editable through a stable REST interface.

Managed OAuth and quotas

Connect your YouTube channel through SocialAPI.ai's managed Google OAuth flow. SocialAPI.ai stores encrypted refresh tokens, refreshes access tokens automatically, and surfaces YouTube Data API quota errors as standard 429 responses so your integration can back off gracefully.

Simple, honest pricing.

Reading comments, DMs, and mentions is free and unlimited on every plan. Paid plans start at $29/mo with unlimited posts and interactions. The free tier needs no credit card.

Frequently asked questions

What developers ask before they ship YouTube.

Can I upload YouTube Shorts through SocialAPI.ai?

Yes. Shorts are published through the same /v1/posts endpoint as regular videos. As long as the source media meets YouTube's Shorts requirements (vertical aspect ratio, under 60 seconds), YouTube classifies it as a Short automatically.

Do I need my own Google Cloud project?

No. SocialAPI.ai operates a managed Google Cloud OAuth app with YouTube Data API access. Your users connect their YouTube channel through the standard OAuth flow without any setup on your side.

How does SocialAPI.ai handle YouTube API quotas?

Every YouTube Data API call costs quota units. SocialAPI.ai batches reads where possible and returns HTTP 429 with a clear error code when YouTube's quota is exhausted. You can detect the error and back off, or contact us to discuss a quota extension request with Google.

Can I schedule a YouTube video to publish later?

Yes. Set the visibility to private and pass a publish_at RFC 3339 timestamp inside platform_data.youtube. YouTube will flip the video to public at the scheduled time automatically.

Is YouTube available on the free tier?

Yes. YouTube is included in every SocialAPI.ai plan, including the free tier. Reads are free; uploads and comment replies count against your monthly post and interaction limits.
