What is a unified HRIS API, and how is it different from a direct integration?

A unified HRIS API provides one canonical data model and a single authentication flow that map to many underlying HR systems. Instead of building and maintaining a separate integration per system, you build once and reach every connected platform. Apideck normalizes fields, pagination and auth across platforms so the data looks the same no matter which HR system it comes from.

Which HR and payroll systems does Apideck support?

Apideck’s HRIS API connects to more than 50 HR and payroll systems, including BambooHR, Workday, Personio, Gusto, Deel, Rippling, HiBob, SAP SuccessFactors, ADP Workforce Now, Sage HR and Namely. The full, current list of connectors is shown on this page.

What HR data can you sync with the HRIS API?

You can sync employees, companies, departments, time off requests, payrolls, employee payrolls and employee schedules, all through one canonical schema.

Does the HRIS API support both reading and writing data?

Yes. The HRIS API supports reading employee, payroll and time off data, and writing is supported where the underlying HR platform allows it, all through one consistent interface.

How does authentication work across different HR systems?

Apideck handles OAuth, token handling and connection management for every HR platform on your behalf. Your users connect their HR system once through a single flow, and Apideck manages the credentials and connection state across all of them.

Does Apideck support real-time updates and webhooks for HR data?

Yes. Apideck provides both native and virtualized webhooks, so your application can receive real-time updates when HR data changes, even for platforms that do not offer native webhooks.

How long does it take to build HRIS integrations with Apideck?

Because you integrate once against a single unified API rather than building a separate integration per platform, teams typically launch HRIS integrations in weeks rather than the months required to build and maintain each connector directly.

What is an HRIS API?

An HRIS API is a programmatic interface for reading and writing human resources data such as employees, companies, departments, payrolls and time off requests from HR and payroll platforms.

A unified HRIS API goes further by mapping one canonical data model and a single authentication flow to many HR systems at once, so you build one integration instead of one per platform.

Apideck’s HRIS API connects to 60+ HR and payroll systems, including BambooHR, Workday, Personio, Gusto, Deel, Rippling, through one canonical data model and a single set of endpoints.

Unified HRIS API vs. building direct integrations

What changes when you connect once through a unified API instead of building and maintaining a separate integration for each HR system.

HRIS API: unified API compared with building direct integrations
	Apideck unified HRIS API	Building direct integrations
Integration setup	One integration covers every connected HR system.	A separate build for each platform, each with its own API.
Data model	One canonical schema normalizes fields across all HR systems.	Different data models, taxonomy and pagination per platform.
Authentication	A single OAuth, token handling and connection flow, done for you.	A separate auth strategy and token handling per platform.
Maintenance	Apideck absorbs upstream API changes and version updates.	Your team tracks and fixes breaking changes on every platform.
Adding coverage	Add new HR systems without writing new code.	Engineering effort grows with each platform you add.
Time to launch	Launch HRIS integrations in weeks.	Months of engineering per platform.

A new way of building
HRIS integrations

HRIS Integrations in hours – not weeks. Simplify integration development by using a normalized HRIS API with the most popular HRIS software.

Traditional integration development

Building APIs on a one-to-one basis can be a challenge. A lack of standardized APIs makes it difficult to scale your integration strategy. Maintaining them can even be a bigger challenge.

Juggle with different API styles
Fragmented taxonomy
Limited amount of documentation
Different auth strategies
Different pagination styles
Plethora of data models
