ADP offers multiple integration paths depending on which ADP product you are using. ADP Workforce Now, ADP Vantage, ADP GlobalView, ADP Celergo, and ADP’s country-specific products each have different APIs, different data formats, and different integration requirements. There is no single ADP API that covers all products and all countries.

For multinational companies, the challenge is compounded: you might use ADP GlobalView or ADP Celergo as your multi-country payroll aggregator, but ADP itself connects to local providers that each have their own integration requirements. Adding a new country or switching a local provider under ADP’s umbrella triggers a new integration project.

datascalehr integrates with ADP across multiple products. The platform is in production with ADP Celergo and has deep experience with ADP’s data structures from the founder’s 15+ years building ADP GlobalView. KMod™ has learned ADP-specific patterns across multiple products and countries.

The integration works bidirectionally: data flows from your HCM (Workday, SAP, Oracle) through datascalehr to ADP, and payroll results flow back. The context layer handles format conversion, field mapping, and jurisdiction-specific validation in both directions. With 1.5 million+ validated mapping decisions and 1,000+ live connectors, adding a new ADP country connection uses patterns already validated by previous deployments.
