Rate Limits

API Limits

TikTok's Content Posting API enforces strict rate limits and processes videos asynchronously (1-2 min processing time). Late automatically queues requests, manages backoff logic, polls for publish confirmation, and retries on transient failures. You get a webhook notification when your TikTok post goes live — no polling needed on your end.

Late handles all rate limiting automatically. We queue and retry requests as needed.

Start building with TikTok API

TikTok's official Content Posting API requires a developer app registration, complex OAuth 2.0 flows, video chunk uploads, and asynchronous status polling. Late eliminates all of that. Connect TikTok accounts through our OAuth flow, then use one simple POST request to publish or schedule videos, photo carousels, and text posts. Late handles video transcoding, rate limiting, retry logic, and webhook notifications automatically — so you can focus on building your product, not wrestling with TikTok's API.
