API Connectivity and Getting Started

Learn more about our two options for you to connect with API and how to get started. 

Connectivity

Using a Representational State Transfer (REST) connection, API data is returned in a JavaScript Object Notation (JSON) format. There are two connectivity options for API:

  1. Link API: Connect to us directly through a secure connection for all available API types.
  2. API Extended X12: API data is returned as an extension to EDI transaction responses. Currently available for claim status only, but eligibility and benefits will be available soon.

Getting Started

Link API:

  • Send an email to physician_esolutions@uhc.com to request a consultation. Include your name, title, organization name, email address and phone number. We will contact you to review options, compatibility and connection terms.
  • Additional Steps for Health Care Providers:
    • Register in Link for an Optum ID, if you haven’t already. Refer to the New User Registration Guide for instructions.
    • Register all Tax IDs connected to your organization by requesting multi-TIN access.
    • The Password Owner of your organization needs to log in using their Optum ID to ensure it’s a current, active account.

API Extended X12:

  • To establish connectivity for API Extended X12, a direct connection to UnitedHealthcare is required. 
  • A direct connection is not required if you are receiving API data from your clearinghouse. Contact your clearinghouse to inquire about the UnitedHealthcare data they have available through their API services.
  • If you’re interested in an API Extended X12 connection, send an email to physician_esolutions@uhc.com to request a consultation. Include your name, title, company name, email address and phone number. We will contact you to discuss API options, compatibility and connection terms.
