Steps
Authenticate to the Harvest API v3 (https://harvest.greenhouse.io/v3/...) with your issued API key or OAuth2 token.
Request a list endpoint (e.g. GET /v3/candidates) with per_page between 1 and 500 (default 100).
Read the Link response header for a rel="next" URL rather than constructing your own cursor — v3 uses opaque cursor-based pagination, not page numbers.
On subsequent requests pass only the cursor from the Link header — combining it with other query filters or per_page on the same call returns a 422.
Watch X-RateLimit-Limit/Remaining/Reset headers on every call; limits are enforced on a rolling ~30-second window.
On a 429, back off and retry only after the Retry-After header's duration has elapsed.
Known gotchas
Don't hand-build or modify cursor values — they're opaque tokens tied to the original query.
Older v1/v2 endpoints use offset-style pagination with different rate-limit semantics than v3 — don't mix documentation.
Token/auth requests are rate-limited separately from data requests on their own ~60-second window.
