Why Build Your Own TikTok API Integration When Ours Already Works?

TikTok's API changes every quarter. Instagram's OAuth flow breaks randomly. YouTube's quota system is a nightmare. We've spent 2 years handling these edge cases so you don't have to. One API, zero maintenance headaches.

  • Automated OAuth2 LifecycleRefresh tokens, access scopes, and session storage are fully abstracted.
  • Intelligent Media TranscodingServer-side FFmpeg processing for codec compliance, resizing, and thumbnail extraction.
  • Event-Driven ArchitectureReceive JSON payloads for `post.published`, `processing.failed` events in real-time.

Whitelabel OAuth Delegation

Flow: End-User → Your Domain → Proxy Auth → Token Storage

UserBrowserYourAppApiProxyProvider
Click "Connect TikTok"
Redirects to api.multi-upload-tool.com/connect
Initiates OAuth2 Handshake
Returns Access Token + Refresh Token
Store Tokens Encrypted (AES-256)
Redirect Back ?connection_id=123

Zero-Trust Token Handling

Your application never sees the raw provider tokens. We issue a scoped connection_id you use to perform actions.

Custom Domain Support

Map the connection flow to a subdomain like auth.yourdomain.com for a completely seamless experience.

Ship Your Social Media Integration 10x Faster

Building TikTok, YouTube, and Instagram integrations from scratch takes 3-6 months. Our API gets you to production in a weekend.

One Endpoint for 5 Platforms

Stop maintaining 5 separate API integrations. POST to /v1/upload with your video and target platforms. We handle the rest. Same response format, same error codes, everywhere.

OAuth Headaches? Gone.

TikTok's OAuth flow changes broke 3 times last year. YouTube's refresh tokens expire randomly. We handle all token management, refresh cycles, and scope changes. You just store the connection ID.

Webhooks for Everything

Get notified when uploads complete, fail, or get flagged. No polling required. Just register your webhook URL and receive JSON payloads for post.published, processing.failed, and more.

Common Questions for Developers

Everything you need to know about integrating with the Universal Social Media API.

Does the API support auto-publishing to TikTok and Instagram Reels?

Yes. Our Universal Social Media API allows you to schedule and auto-publish short-form video content directly to TikTok, Instagram Reels, YouTube Shorts, and Facebook Reels via a single endpoint.

How do you handle OAuth and token refreshing logic?

We manage the entire OAuth lifecycle invisibly. You simply redirect your users to our connect URL, and we handle permissions, access tokens, and automatic refreshing so authentication never breaks for your application.

Is there a limit to the file size or video duration?

We support video files up to 256GB and durations compliant with each platform's specific limits (e.g., 60 minutes for TikTok, 60 seconds for Shorts). We automatically validate assets against platform rules before upload.

Do I need my own developer keys (Client ID/Secret) for each platform?

No. By default, you can use our pre-approved social apps to get started immediately.

How much does the TikTok & YouTube API integration cost?

We offer a freemium model for developers. You can start testing the API for free. For production workloads, our pricing scales based on the number of active connected accounts.
