How to Schedule TikTok Videos Automatically Using the API

Manually uploading videos to TikTok every day is time-consuming — especially if you manage multiple accounts or produce content at scale. The Multi Upload Tool API lets you schedule and publish TikTok videos programmatically, freeing you to focus on what matters: creating great content.

Why Automate TikTok Publishing?

The TikTok algorithm rewards consistency. Accounts that post regularly — at the right times — see significantly more impressions. But maintaining that cadence manually is unsustainable. Automation solves this by letting you batch-produce content and schedule it to go out at optimal times.

What You Need to Get Started

Before making your first API call, you need three things: an API key, a connected TikTok account, and the video file you want to upload.

1. 1.Get your API key — Sign in to Multi Upload Tool and go to Settings → API Keys to generate a key.
2. 2.Connect a TikTok account — In the dashboard, click "Connect Account" and authorize TikTok. You'll receive an accountId to use in API calls.
3. 3.Prepare your video — TikTok requires MP4 or MOV files, 9:16 aspect ratio, maximum 500 MB.

Making Your First API Request

The upload endpoint accepts a multipart form or a public video URL. Here's a minimal example using curl to post a video immediately:

curl -X POST https://api.multi-upload-tool.com/upload/tiktok \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "accountId=acc_123abc" \
  -F "caption=My first automated TikTok post #automation" \
  -F "video=@/path/to/video.mp4"

A successful response returns a postId you can use to track status:

{
  "success": true,
  "postId": "post_7f3a9b2c",
  "status": "queued",
  "platform": "tiktok",
  "estimatedPublishAt": "2026-01-15T14:00:00Z"
}

Scheduling a Post for Later

To schedule instead of posting immediately, add a scheduledAt field in ISO 8601 format. The API will queue your video and publish it at exactly that time, even if your server is offline.

const response = await fetch('https://api.multi-upload-tool.com/upload/tiktok', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.MUT_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    accountId: 'acc_123abc',
    videoUrl: 'https://cdn.yoursite.com/video.mp4', // public URL
    caption: 'Posted at peak time automatically ✨ #automation',
    scheduledAt: '2026-01-16T09:00:00Z', // ISO 8601 UTC
    hashtags: ['automation', 'contentcreator', 'productivity'],
  }),
})

const { postId, status } = await response.json()
console.log(`Scheduled: ${postId} — status: ${status}`)

Bulk Scheduling Multiple Videos

The bulk endpoint lets you schedule an entire content calendar in one request — perfect for agencies or creators batching a week of content:

const posts = [
  {
    platform: 'tiktok',
    accountId: 'acc_123abc',
    videoUrl: 'https://cdn.yoursite.com/monday.mp4',
    caption: 'Start your week strong 💪',
    scheduledAt: '2026-01-20T09:00:00Z',
  },
  {
    platform: 'tiktok',
    accountId: 'acc_123abc',
    videoUrl: 'https://cdn.yoursite.com/wednesday.mp4',
    caption: 'Midweek motivation 🔥',
    scheduledAt: '2026-01-22T09:00:00Z',
  },
  {
    platform: 'youtube',          // post to YouTube Shorts at the same time
    accountId: 'acc_yt456',
    videoUrl: 'https://cdn.yoursite.com/wednesday.mp4',
    title: 'Midweek Motivation #Shorts',
    scheduledAt: '2026-01-22T09:00:00Z',
  },
]

const response = await fetch('https://api.multi-upload-tool.com/upload/bulk', {
  method: 'POST',
  headers: { Authorization: `Bearer ${process.env.MUT_API_KEY}` },
  body: JSON.stringify({ posts }),
})

Best Practices for Automated TikTok Posts

Monitoring Post Status

After scheduling, you can poll the status endpoint or set up a webhook to receive real-time notifications when a post goes live or fails:

// Poll status
const status = await fetch(`https://api.multi-upload-tool.com/posts/${postId}`, {
  headers: { Authorization: `Bearer ${process.env.MUT_API_KEY}` },
}).then(r => r.json())

// status.status can be: 'queued' | 'processing' | 'published' | 'failed'
console.log(status.status, status.publishedAt, status.tiktokPostId)

For production systems, webhooks are more efficient than polling. Register a webhook URL in your dashboard and the API will POST a notification the moment each video publishes.
