  title: RXNT Authentication Clinical Data API
  version: '1.0'
  description: 'ONC-certified Clinical Data API (CDAPI) that exposes a patient''s Common Clinical Data Set (CCDS) to registered third-party applications and patient representatives, fulfilling ONC 2015 Edition certification criteria 45 CFR 170.315(g)(7) Application Access - Patient Selection, (g)(8) Data Category Request, and (g)(9) All Data Request.


    Access is partner-gated: third parties must first register with RXNT (support@rxnt.com) to receive login credentials. The AuthenticateUser operation returns a time-limited Token and Signature that must be supplied in the body of every subsequent request. Patient clinical data is returned as CCDS XML embedded (PatientCCDSXml) inside a JSON response envelope.


    Modeled by API Evangelist from the publicly documented RXNT Clinical Data API reference (github.com/RXNT/RxNTClinicalDataAPI, archived 2021-12-17). Endpoint paths, methods, and field names reflect that documentation; request and response schemas below are honestly modeled from the documented fields.'
