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, in the API Commons Rate Limits shape.

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

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

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.
