Greenhouse Rate Limits

Greenhouse Harvest API rate limits use a rolling 10-second window. The actual per-window cap is communicated dynamically via the X-RateLimit-Limit response header (it varies by approved partner / customer-built integration). When exceeded, the API returns HTTP 429 with X-RateLimit-Reset (Unix timestamp) and Retry-After (seconds). Other Greenhouse APIs (Job Board, Candidate Ingestion, Onboarding, Webhooks) have their own documented limits with the same 429 + Retry-After signaling.

Greenhouse Rate Limits is the machine-readable rate-limit profile for Greenhouse on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests_per_period and varies.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include Rate Limiting, ATS, Recruiting, and HR.

Policies

Backoff Strategy
When a 429 is received, sleep for the seconds value in Retry-After (or until X-RateLimit-Reset Unix timestamp) before retrying. Apply jitter on additional retries.
Header-driven throttling
Inspect X-RateLimit-Remaining on every successful response to throttle preemptively before the next 429.
Approved-partner allowance
Higher rate-limit allowances are granted to approved Greenhouse partners and customer-built integrations.
