Flexpa

Flexpa is a patient-access platform that lets applications connect a patient to their health insurance plan and retrieve claims and clinical data as normalized FHIR R4 resources. Patients authorize access through Flexpa Link / OAuth 2.0 PKCE, and applications read ExplanationOfBenefit, Coverage, Patient, and other resources from a single FHIR API at https://api.flexpa.com.

Flexpa publishes 4 APIs on the APIs.io network, including Access Tokens API, Claims Data API, FHIR API, and 1 more. Tagged areas include Healthcare, FHIR, Patient Access, Claims Data, and Health Insurance.
