HubSpot API Rate Limits Explained

HubSpot's API rate limits are one of the most common causes of integration failures. Understanding how they work is essential for building reliable integrations.

HubSpot has two types of limits: daily limits and burst limits. Daily limits cap the total number of API calls per day (typically 500,000 for most paid plans). Burst limits cap how many calls you can make in a 10-second window (typically 100-150 depending on the endpoint).

Burst limits are where most integrations fail. If you're syncing thousands of records and making API calls in a tight loop, you'll hit the burst limit quickly. The API returns a 429 status code, and if your integration doesn't handle it, the sync fails.

The solution is implementing exponential backoff with jitter. When you receive a 429, wait before retrying—and increase the wait time with each subsequent failure. Adding randomness (jitter) prevents thundering herd problems when multiple processes retry simultaneously.

Batch operations can help reduce API calls. Instead of updating records one at a time, use HubSpot's batch endpoints to update up to 100 records in a single call. This dramatically reduces your API usage.

RevOps Connect handles all of this automatically. Our runtime implements intelligent rate limiting, automatic retries with backoff, and batching to maximize throughput while staying within HubSpot's limits.
