Care Connect API


The Care Connect RESTful APIs within this site have been developed collaboratively by NHS Digital and the INTEROPen community. These APIs aim to better support the delivery of care by opening up information and data held across different clinical care settings through the use of nationally defined INTEROPen FHIR® resources.

The INTEROPen vision is to create a library of nationally defined HL7® FHIR® resources and interaction patterns that implementers can adopt to simplify integration and interoperability within UK health and social care.


(Note: API has links to Profiles but these are may generate a warning as they are on a temporary site.)
