Test Kit Version: 5.4.2
Maturity: High
SMART App Launch
US Core
Bulk Data

The ONC Certification (g)(10) Standardized API Test Kit is a testing tool for Health IT systems seeking to meet the requirements of the Standardized API for Patient and Population Services criterion § 170.315(g)(10) in the ONC Certification Program. It is an approved test method for the § 170.315(g)(10) test procedure.

This test kit includes a simulated conformant FHIR API that can be used to demonstrate success for all tests. This simulated API is open source and is available on GitHub. Visit the walkthrough for a demonstration of using these tests against the provided simulated FHIR API.

Systems may adopt later versions of standards than those named in the rule as approved by the ONC Standards Version Advancement Process (SVAP). Please select which approved version of each standard to use, and click ‘Create Test Session’ to begin testing.


The ONC Certification (g)(10) Standardized API is actively developed and updates are released monthly.

The test kit currently tests all requirements for the Standardized API for Patient and Population Services criterion § 170.315(g)(10). This includes:

  • SMART App Standalone Launch with full system access

Providing Feedback and Reporting Issues

We welcome feedback on the tests, including but not limited to the following areas:

  • Validation logic, such as potential bugs, lax checks, and unexpected failures.
  • Requirements coverage, such as requirements that have been missed, tests that necessitate features that the IG does not require, or other issues with the interpretation of the IG’s requirements.
  • User experience, such as confusing or missing information in the test UI.

Please report any issues with this set of tests in the issues section of the repository.
