How to Connect Claude to Greenhouse (No Official Connector)
No — there’s no official Claude connector for Greenhouse. It isn’t in Anthropic’s Connectors Directory, so Claude can’t open a job, read candidates, or move an applicant through your pipeline on its own. Greenhouse is a specialized applicant tracking system, and it sits outside the horizontal app catalog Claude’s connectors cover.
That doesn’t mean recruiters are stuck flipping between Greenhouse and a chat window. Greenhouse has a REST API — the Harvest API — and any AI agent that lets you bring your own API key can use it. Here’s why the connector gap exists, what you can automate, and how to wire Greenhouse into an agent that keeps your pipeline moving on its own.
Why there’s no Greenhouse connector
Greenhouse is an ATS built for recruiting and talent teams — structured hiring, job reqs, candidate applications, interview kits, scorecards, and offers. Anthropic’s Connectors Directory leads with broad horizontal apps like Gmail, Slack, and the big CRMs, and a specialized hiring system with its own structured-interview data model isn’t the kind of thing that ships as a first-party connector.
So talent teams end up in one of two spots:
- Claude’s connectors cover a fixed list of first-party apps. Greenhouse isn’t on it, so Claude can’t see a candidate or a stage without you pasting the data in.
- No-code automation tools do list Greenhouse — you can set up basic field-mapping triggers like “new candidate → add a spreadsheet row.” But those are one-to-one data moves, not an agent that reads a candidate’s history and decides the next step.
What most people miss: Greenhouse already exposes the Harvest API, a REST API with API-key authentication that reads and writes candidates, jobs, applications, and more. The data is reachable — you just need an agent that will talk to it with your own credentials.
The API key that changes the answer
Carly connects to 200+ tools out of the box, but it also does something the connector directories don’t: it lets you bring your own API key to reach anything with a REST API. Greenhouse has one, so that’s your bridge.
You generate a Harvest API key inside Greenhouse, hand it to Carly, and Carly can then read and write your Greenhouse data as part of a real workflow — the same way it works with a natively supported app. No connector directory required, no waiting for an official integration.
And because Carly runs in the cloud on triggers, this isn’t “answer me in a chat.” It’s recruiting work that happens on its own — a candidate applies, an interview wraps, a scorecard is submitted, and the agent acts.
What you can automate once it’s connected
With Greenhouse reachable through the Harvest API, an agent can handle the coordination work that usually eats a recruiter’s day:
- Triage new applications — when a candidate applies, the agent reads the application, summarizes the resume against the job, and flags strong fits for a recruiter to review.
- Move candidates forward — advance applicants between stages, add notes, and keep the pipeline current the moment a decision is made.
- Chase interview logistics — when an interview is scheduled or a scorecard is due, nudge the interviewers and update the candidate record so nothing stalls.
- Draft and send candidate email — write the outreach, rejection, or scheduling note and send it through Gmail or Outlook, logged back against the candidate.
- Answer pipeline questions on demand — “how many candidates are stuck in onsite for the Staff Engineer req?” answered against live Greenhouse data.
How to connect Greenhouse to Carly
- In Greenhouse, generate a Harvest API key (under Configure → Dev Center → API Credentials; your Greenhouse admin can create one with the right permissions).
- Paste your API key into Carly on the integrations page.
- Describe the workflow in plain English — “when a new candidate applies to an open req, summarize the resume against the job and email me the shortlist” — and Carly interviews you, then builds it.
Your key stays yours: you can rotate or revoke it in Greenhouse at any time.
Claude connector vs. no-code tools vs. Carly
| Claude | No-code tools | Carly | |
|---|---|---|---|
| Official Greenhouse connector | No | Basic triggers | Via your API key |
| Reads & writes candidates / applications | No | Limited | Yes |
| Acts on triggers / events | No | Field-mapping only | Yes, 24/7 in the cloud |
| Reasons over a candidate’s history | In chat only, if you paste data | No | Yes |
| Sends email as part of the flow | Draft-only | No | Yes (Gmail + Outlook) |
| Works while your laptop is closed | No | Yes | Yes |
Claude is a strong assistant inside a chat — but with no Greenhouse connector, it can’t see your pipeline unless you paste it in. No-code tools can move data on basic triggers, but they won’t reason over a candidate. Carly reaches Greenhouse through your own Harvest API key and acts on it as part of a workflow that runs on its own.
Frequently Asked Questions
Does Claude integrate with Greenhouse?
Not directly. Greenhouse isn’t in Anthropic’s Connectors Directory, so Claude can’t read or write your ATS data on its own. You can paste candidate details into a chat and have Claude reason over them, but there’s no live connection. To connect Greenhouse to an AI agent, you need a tool that supports its REST API — like Carly, which connects via your own API key.
Does Greenhouse have an API?
Yes. Greenhouse exposes the Harvest API, a REST API with API-key (Basic auth) access that reads and writes candidates, jobs, applications, scorecards, and more. Your Greenhouse admin can generate a key with the right permissions from the Dev Center.
Can I connect Greenhouse to an AI agent?
Yes. Because Greenhouse has the Harvest API, any agent that lets you bring your own API key can read and write your ATS data. Carly does this — you generate a key in Greenhouse, add it to Carly, and it can triage applications, advance candidates, and send outreach automatically.
What can an AI agent actually do in Greenhouse?
Triage new applications, summarize resumes against a job, advance candidates between stages, add notes, chase interview logistics, and draft and send candidate email — all triggered by events like an application arriving or an interview wrapping, rather than you prompting in a chat.
How much does this cost?
Carly’s AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Your Greenhouse Harvest API access is part of your existing Greenhouse plan.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
