# Rate-Limit Downstream APIs with Task Queues

**[Temporal](https://daily.dev/sources/temporal)** · 1 min read · 0 upvotes · 0 comments

## Summary

When integrating with external APIs like SendGrid, Stripe, or OpenAI, exceeding rate limits causes 429 errors, failed workflows, and potential account suspension. Temporal's validated pattern addresses this by assigning a dedicated Task Queue per rate-limited API and configuring three key settings: a global rate limit across all workers (`max_task_queue_activities_per_second`), an optional per-worker rate limit (`max_activities_per_second`), and a concurrency cap (`max_concurrent_activities`). This keeps Activities within provider quotas without manual throttling logic.
