Hailey integrates seamlessly with your HR tech stack: keeping data accurate, workflows smooth, and everyday HR simpler for our shared users.
How to get started
Build an integration with Hailey in three steps:
- Request sandbox access: fill in the form to get your sandbox credentials and start exploring safely.

Our Open API
Hailey’s open REST API lets you connect your product directly with core people data — so you can automate workflows, streamline HR tasks, and deliver a smoother experience for our shared customers.
What you can connect
- Employee and organizational data
- Employment status and details
- Time off, roles, and core HR fields
- Relevant custom fields depending on your use case
List your integration at Hailey's Marketplace
A dedicated place to be discovered
Your integration gets its own page in the Hailey Marketplace, making it easy for customers to find you and understand the value you bring.
Tell your story — within a clean, consistent framework
Every integration page follows a clear structure, but within that layout you can highlight what your product does best and why it matters for our shared users.

Built a Hailey integration for a customer?
Are you a consultancy or integration platform that has built an integration with Hailey? We can list it on our integrations page, with its own card marked "Built by [your company]" that links to your page.
To be listed, the integration needs to:
- Be generic, so it can be offered to more customers than the one it was built for
- Have a landing page on your website covering data flows, how to get started, pricing and contact details
We prioritise integrations our customers ask for the most.
