The Best Greenhouse Integrations and Apps in 2026
Greenhouse is where a lot of recruiting teams run their pipeline, scorecards, and hiring workflows — but it’s only as useful as the tools it talks to. The good news: Greenhouse’s partner directory has 450+ integrations, one of the largest in recruiting. The gap: if the tool you need isn’t in the directory, you’re back to copying candidate data between systems by hand.
Here are the Greenhouse integrations actually worth setting up, grouped by what they do — and then the way to connect Greenhouse to anything with an API, even when no native integration exists.
Sourcing and job boards: LinkedIn Recruiter, Indeed, and ZipRecruiter
- LinkedIn Recruiter (System Connect) — access real-time candidate data and see LinkedIn profiles inside Greenhouse without switching tabs.
- Indeed and ZipRecruiter — post jobs and pull applicants straight into your Greenhouse pipeline.
Assessments: HackerRank, Codility, and Criteria
- HackerRank and Codility — send technical assessments from a stage and get scored results back on the candidate profile.
- Criteria — run aptitude and skills tests tied to the candidate record.
Background checks: Checkr
- Checkr — trigger a background check the moment a candidate hits the Offer stage, with results landing back on the profile so recruiters never leave the ATS.
Scheduling and meetings: Google Calendar, Microsoft, Calendly, and Zoom
- Google Calendar / Meet and Microsoft 365 / Teams — schedule interviews and generate meeting links from the candidate record.
- Calendly — let candidates self-schedule interviews that sync to Greenhouse.
- Zoom — auto-create interview links tied to the schedule.
E-signature: DocuSign
- DocuSign — send offer letters for signature from Greenhouse and track status back on the candidate.
Communication: Slack
- Slack — push interview reminders, scorecard nudges, and hiring updates into the channels your team already lives in.
HRIS and onboarding: Workday, BambooHR, and Rippling
- Workday — hand off hired candidates to Workday so onboarding starts without rekeying data.
- BambooHR and Rippling — the same clean handoff for teams running those HRIS platforms.
CRM and no-code automation: Gem and Zapier
- Gem — a recruiting CRM that syncs prospects and outreach with your Greenhouse pipeline.
- Zapier — connect Greenhouse to thousands of apps with simple triggers (“candidate moves stage → do X”). Good for basic field-mapping, not for reasoning over pipeline data.
The AI way to connect Greenhouse to anything: Carly
Native connectors cover the big recruiting systems. But the moment you need Greenhouse tied to a tool that isn’t in the directory — or you want something smarter than “stage change → copy field” — you’ve hit the ceiling of native integrations and no-code triggers.
Carly is an AI executive assistant that connects to 200+ tools and, crucially, lets you bring your own API key to connect to anything with a REST API — Greenhouse’s Harvest API included. Instead of a fixed catalog, you get an agent that:
- Acts on triggers, 24/7 in the cloud — when a candidate changes stage, an interview is scheduled, or a scorecard is due, Carly does the next step without you in the app.
- Reasons over your data — not just “copy this field,” but “read the scorecards, summarize the panel’s feedback, and draft the offer email for my review.”
- Ties Greenhouse to the rest of your stack — updating a candidate becomes one step in a workflow that also touches email (Gmail and Outlook), calendar, and tasks.
- Builds the workflow from a plain-English description — tell it “when a candidate reaches the Offer stage, draft the offer letter and notify the hiring manager in Slack” and it interviews you, then builds it.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. See the full Claude + Greenhouse integration guide for how the API-key connection works.
How to connect Greenhouse to a tool with no native integration
- In Greenhouse, generate a Harvest API key (Configure → Dev Center → API Credential Management).
- Paste your Greenhouse API key into Carly on the integrations page.
- Describe the workflow in plain English, and Carly builds it — connecting Greenhouse to whatever else you need, on triggers, without your laptop open.
Frequently Asked Questions
Does Greenhouse have integrations?
Yes. Greenhouse’s partner directory includes 450+ integrations spanning sourcing (LinkedIn Recruiter, Indeed), assessments (HackerRank, Codility, Criteria), background checks (Checkr), scheduling (Google Calendar, Calendly, Zoom), HRIS (Workday, BambooHR, Rippling), and Slack, plus Zapier for no-code automation and the Harvest API for custom connections.
What is the best Greenhouse integration for automation?
For simple triggers, Zapier covers most apps. For automation that acts on triggers and reasons over your pipeline data — and to connect Greenhouse to tools with no native integration — an AI agent like Carly connects via your Greenhouse Harvest API key and runs workflows in the cloud.
How do I connect Greenhouse to an app that isn’t in the directory?
Use the Greenhouse Harvest API. Generate an API key in the Dev Center, then hand it to a platform that supports bring-your-own-API-key connections — Carly does this and can wire Greenhouse to any tool with an API.
How much does an AI automation for Greenhouse cost?
Carly’s AI agents start at $35/month, with non-AI workflow steps running free and unlimited. Your Greenhouse plan and API access are separate.

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."
