When a recruiter or HR manager presses the new hire button in your applicant tracking system, the new employee’s information appears in UKG automatically — nobody retypes it, and you choose whether it lands in UKG Onboarding or UKG Pending Hires. Flexspring connects UKG to any ATS directly, and foundational data, recruiter accounts and employee profiles flow back from UKG so both systems describe your company the same way.
Flexspring builds, hosts, and monitors the connection for you, and its connectors work with the talent acquisition modules inside UKG Pro, UKG Pro Workforce Management and UKG Ready. A custom integration goes live in 8–10 weeks. Flexspring is a UKG Marketplace Partner. With Flexspring, you only pay for the use case or use cases you need.
New hires flow from your ATS into UKG. Everything else flows the other way — from UKG into your ATS — so recruiters and hiring managers work with your real company structures and current employees can apply as internal candidates. Each foundational data set is built as its own use case, because each is driven by a different API.

Flexspring iPaaS does not store employee data beyond temporary transaction logs, and meets SOC 2, GDPR and ISO 27001 standards.

With data integration, when a recruiter or HR manager presses the new hire button in your applicant tracking system, the new employee’s information appears in UKG automatically — nobody retypes it. Recruiters and hiring managers also work with your real company structures instead of a stale copy. A nationwide community bank saved about five hours every other week.
The best way to connect UKG to your ATS depends on your data and business requirements. A standard connector can work for simple data flows, while custom fields and unique business rules require a tailored integration. If you go the custom route, you can build the integration yourself or choose a managed integration like Flexspring’s — built and maintained for you, which is typically faster and cheaper.
