How to Build a Job Board That Connects to Greenhouse, Lever, and 60+ ATS Platforms with a Unified API
October 23, 2025
Most job boards and recruiting platforms rely on applicant tracking systems (ATS) to supply open positions — but every ATS uses different endpoints, authentication methods, and field structures. Building and maintaining per-vendor connectors slows your roadmap and makes keeping listings fresh a constant chore.
Unified.to removes this friction. With one API, you can read active job postings from your customers' ATS systems and publish them on your site or app in real time. Roles stay current, candidate routing stays accurate, and you never have to write custom code for each ATS integration.
When to Use Unified for Job Boards
With a unified API, you can:
- Aggregate and display open roles from multiple ATS sources with one API call.
- Publicize active or published jobs automatically on your site or app.
- Route applicants either to the ATS's native apply page or to your own intake flow.
- Keep listings fresh with webhook-driven updates or managed polling.
Unified Objects & Key Fields
| Object | Description | Key Fields |
|---|---|---|
| Job | A requisition or posting to display | name, description, status, public_job_urls, addresses, employment_type, departments, remote, number_of_openings |
| Company | Hiring organization metadata | id, name, website_url, address, phone |
| Webhook | Change notifications for jobs | object_type, event |
