TikTok posting API for UGC videos and slideshows

What you can post to TikTok

• Videos. format: 'video' with one MP4 URL. It publishes as a normal TikTok video with your caption and hashtags.
• Photo posts (slideshows). format: 'slideshow' with 2 or more image URLs. TikTok's Content Posting API accepts up to 35 images per photo post. You can let TikTok add recommended music with auto_music: true.
• Drafts. Set tiktok.draft: true and the content lands in the creator's TikTok inbox instead of going live. The creator opens it, adds a trending sound, and posts it by hand.
• AI-generated label. Set tiktok.ai_generated: true to apply TikTok's AI-generated content label to the post.

How it works

1. Create a connect link with POST /v1/accounts/connect and platform: 'tiktok'. Send it to the creator. They log in with TikTok and approve posting.
2. Upload media with POST /v1/media or pass public URLs. We host the files, so you don't need to verify a domain with TikTok.
3. Call POST /v1/posts with the account IDs, format, caption and an optional scheduled_at.
4. Get a post.published webhook with the public TikTok URL, or post.failed with TikTok's reason.

curl https://ugcapi.dev/v1/posts \

    "accounts": ["acc_tt_01"],
    "format": "slideshow",
    "media": ["https://cdn.example.com/s1.jpg", "https://cdn.example.com/s2.jpg", "https://cdn.example.com/s3.jpg"],
    "caption": "3 things I wish I knew before buying #skincare",
    "options": { "tiktok": { "auto_music": true, "ai_generated": false } }
  }'

TikTok rules that shape your posting

TikTok's Content Posting API has rules every integration lives with. Knowing them saves you from confusing failures.

The full background is in our TikTok Content Posting API audit guide. For cadence advice per account, read UGC posting cadence.

Many creator accounts, one schedule

UGC rarely means one account. With campaigns you send 100 slideshows and 10 TikTok accounts with a cadence like one post a day each. We schedule them round-robin with staggered minutes, so accounts don't all post at 9:00 sharp. That keeps each account under TikTok's daily cap and looks like normal human posting.

Pricing

One TikTok post to one account is one post credit. You get 50 free posts to test, then packs start at $10 for 1,000 posts. Credits never expire and there are no per-account fees. See pricing.
