Why Zernio vs TikTok Content Posting API?

TikTok Content Posting API

  • ✗Complex OAuth with TikTok developer app approval
  • ✗Strict rate limits with complex backoff logic
  • ✗Video must meet strict encoding requirements
  • ✗Frequent API changes require constant updates
  • ✗Build separate integrations per platform

Zernio API

  • ✓Simple API key - start in 30 seconds
  • ✓Automatic retries & queue management
  • ✓Upload directly - we transcode for TikTok
  • ✓Zero maintenance forever
  • ✓One API for 15 platforms

Save 4-6 weeks of development. Ship TikTok API integration today, not next month.

How It Works

  1. 1.
    Connect Your Account
    Link your TikTok account through our dashboard. One-click OAuth - we handle all the TikTok permissions.
  2. 2.
    Build Your Integration
    Use our simple REST API to schedule videos with captions and hashtags. Same pattern works for all 15 platforms.
  3. 3.
    We Handle the Rest
    Zernio publishes at your scheduled time, retries on failures, and notifies you via webhooks. You never touch TikTok's API directly.

Features

Ship Faster

Go from zero to posting in under 30 seconds. No TikTok developer app approval process - just get your API key and start building.

Official API, Zero Hassle

We use TikTok's official Content Posting API under the hood. You get full compliance and reliability without the integration pain.

We Handle the Hard Parts

Rate limits, token refresh, video transcoding, error handling - all managed for you. Focus on your product, not infrastructure.

Frequently Asked Questions

How long does TikTok API approval take?
└TikTok's Content Posting API approval can take days to weeks. With Zernio, there's no approval process; get your API key and start posting immediately.
What video formats does the TikTok API accept?
└Upload MP4 videos up to 10 minutes (standard accounts) with 1080p resolution. Zernio automatically transcodes to formats TikTok accepts.
Can I schedule TikTok posts in advance?
└Yes. Set a scheduledFor timestamp in your API call and Zernio publishes at the exact time. We handle rate limits and queue requests if TikTok imposes temporary throttling.
Can I cross-post TikTok videos to other platforms?
└Absolutely. The same API call can publish to TikTok, Instagram Reels, YouTube Shorts, and 12 other platforms simultaneously.
Can I save a draft on TikTok?
└Yes. Set scheduledFor to null to create TikTok drafts in Zernio, then update the post later with a scheduled time once you're ready to publish.
How much does the TikTok API cost?
└TikTok's Content Posting API is free after approval, but building the integration takes weeks of engineering. Zernio starts at $19/mo with a free tier, and you skip the approval process entirely.
