Why Zernio vs TikTok Content Posting API?

Save 4-6 weeks of development time

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 17 platforms

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

How It Works

Three steps to TikTok automation

1

Profile

default

TikTok

Connect your account

Link your TikTok account through our dashboard. One-click OAuth - we handle all the TikTok permissions.

2

POST /v1/posts

const { data } = await zernio.posts.createPost({
  body: {
    content: 'Launch day! 🚀',
    mediaItems: [{ url: 'https://cdn.acme.com/launch.mp4' }],
    platforms: [
      { platform: 'tiktok', accountId: 'acc_8f2a' },
    ],
    scheduledFor: '2027-01-15T14:30:00',
    timezone: 'Europe/Madrid',
  },
});

Build your integration

Use our simple REST API to schedule videos with captions and hashtags. Same pattern works for all 17 platforms.

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.

TikTok's Content Posting API works with both Creator and Business accounts

Three ways in. Same API behind all of them

Write it yourself with the SDKs, hand it to an agent over MCP, or run it from a shell.

Read the docs
import Zernio from '@zernio/node';
const zernio = new Zernio(); // reads ZERNIO_API_KEY
const { data: post } = await zernio.posts.createPost({
body: {
content: 'Launch day! 🚀',
mediaItems: [{ type: 'video', url: 'https://cdn.acme.com/launch.mp4' }],
platforms: [
