What Is an ATS Integration and Why Does It Matter?
An Applicant Tracking System (ATS) integration is the process of connecting your ATS with other software applications in your HR tech stack, such as HRIS, payroll, background check services, assessment tools, and communication platforms. This connectivity allows for automated, seamless data flow between systems, eliminating manual data entry, reducing errors, and creating a single source of truth. A strong integration strategy is crucial for streamlining the entire talent lifecycle, from sourcing and hiring to onboarding and employee management, ultimately boosting recruiter efficiency and improving the candidate experience.
