What causes this error?

You’ve exceeded TikTok’s API rate limits. The Marketing API enforces both per-second and per-day rate limits depending on the endpoint and your app tier.

How to fix it

1. Read headers: Check X-RateLimit-Remaining and X-RateLimit-Reset response headers to know when you can retry.
2. Implement backoff: Use exponential backoff with jitter when you receive a 429.
3. Batch operations: Use batch endpoints where available instead of making individual calls.
4. Request higher limits: Apply for a higher app tier through TikTok’s developer portal if your volume demands it.
