What can I automate with Greenhouse in Sim?

You can list candidates, get candidate, create candidate, update candidate, and delete candidate with Greenhouse in Sim, plus 45 more Greenhouse tools listed on this page. Each runs as a tool inside an AI agent, so the agent can combine Greenhouse with any other connected service and apply LLM reasoning between steps.

How do I connect Greenhouse to Sim?

(1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a Greenhouse block onto the workflow builder. (4) Connect your Greenhouse account with one-click OAuth, with no credentials to copy. (5) Pick a tool such as "List Candidates", wire up its inputs, and click Run.

How do I list candidates with Greenhouse in Sim?

Add a Greenhouse block to your agent and select "List Candidates" as the tool. Lists candidates from Greenhouse with optional filtering by date, job, or email. Fill in the required fields. Inputs can reference outputs from earlier steps, such as text generated by an AI block or data fetched from another integration.

Can Greenhouse events start a Sim agent automatically?

Yes. Sim supports 8 triggers for Greenhouse: Greenhouse Candidate Hired, Greenhouse New Application, Greenhouse Candidate Stage Change, Greenhouse Candidate Rejected, Greenhouse Offer Created, Greenhouse Job Created, and 2 more. Add a Greenhouse trigger to your agent, and every matching Greenhouse event starts a run with the event data available to the rest of the workflow.
