  • Streamlined plan setup*

    The Policy API automates the passing of plan details and rates from Guardian’s system to ADP Workforce Now®, which helps reduce the setup time and eliminate errors. We do the work for you, from initial case setup to updates at renewal.

  • Fast eligibility updates*

    The Member Benefits API transmits all member transactions from ADP Workforce Now® to Guardian in real-time, eliminating the need for submitting manual eligibility files or building and testing the EDI files. The result is more streamlined process for member coverage status and billing.

  • Seamless EOI application**

    The Evidence of Insurability API provides a seamless experience for employees to complete the evidence of insurability questionnaire within the benefits shopping experience. It provides automatic status updates to the employee and HR team.
