Integration Made Possible
Resources to help you build applications
and connectors using ADP® APIs
Focus on building your data connection application functionality by using our pre-built ADP Developer Core Libraries to connect and consume ADP workforce data.
Introduction to the structure of the ADP REST APIs
ADP APIs are designed using an event based pattern for resource management. This pattern separates the act of retrieving resources and modifying them into separate activities along with providing event notifications that indicate the changes to a resource.
The Workers APIs support the management of workers in an organization. A worker is a person who performs duties and responsibilities for an organization. In that capacity, a worker fills one or more positions via a work assignment. For a given work assignment, a worker is related to the organization as an employee or contractor. The Workers APIs can be used to obtain a list of all workers in an organization and to get information about work assignments.
