API Resource Guide¶
How to use this resource guide¶
This informative resource supplements other public documentation available to help health IT developers certify to the API criteria in the ONC Health IT Certification Program and meet the requirements under the API Conditions and Maintenance of Certification. At the highest level, this document mirrors the organization of paragraphs in the Code of Federal Regulations, including headers for “§ 170.315(g)(10) Standardized API Certification Criterion” (the FHIR®-based standardized API), “§ 170.404 Conditions and Maintenance of Certification” (the broader API behavior requirements), and sub-paragraphs. It also contains standalone sections for topics that generate a lot of questions, like “Real World Testing of APIs” and “Standards Version Advancement Process and APIs.” Efforts have been made to make this resource easily navigable, searchable, and consumable. If you have recommendations to improve this resource, please submit an inquiry to the Health IT Feedback and Inquiry Portal or submit an issue on GitHub.
