Adding AI to Greenhouse Without Disrupting Your Pipeline

Greenhouse is one of the easier ATS platforms to layer AI on top of. The API is real, the webhooks are reliable, custom fields are first-class, and the partner ecosystem is healthy. The goal of any AI integration is the same: get a fit signal in front of the recruiter inside Greenhouse, without making them open another tab.

The integration points that matter

Harvest API for reads

Use Harvest to pull applications and resumes. It is the read-side API, well documented, and rate-limited generously enough for most volumes. Pull on the application created webhook rather than on a schedule so latency stays in seconds, not minutes.

Webhooks for triggers

Enable the application created and application updated webhooks. These are how the intelligence layer learns about new applicants in near real time. The payload includes the application ID, candidate ID, and job ID, which is enough to fetch the full record.

Custom application fields for write-back

Create a small set of custom fields on the application object: priovera_fit_score, priovera_tier, priovera_rationale, priovera_evidence. Write the evaluation back into these fields so recruiters see the result inside the Greenhouse pipeline view and can filter by it.

A clean default configuration

• Score every new applicant within five minutes of submission.
• Write fit score and tier into custom fields on the application.
• Set up a saved view sorted by fit score, descending, per role.
• Optional: auto-move clear non-matches to a "Polite reject" stage with an email template attached.
• Keep every yes decision human, always.

What to avoid

• Auto-rejecting on score alone without a human spot-check window.
• Overwriting Greenhouse stage transitions from the integration: stages belong to the recruiter, scores belong to the integration.
• Burying the score in a note instead of a custom field; if it cannot be sorted, it will not be used.

The recruiter test

The integration is working when a recruiter opens Greenhouse in the morning, sorts the inbox by fit score, and works the top of the list without thinking about it. No new tab, no new tool, just a better ordering of the queue they already use.
