Lifen

Lifen (Honestica SAS, Paris) is a French digital-health company whose Lifen Platform exposes FHIR R4 APIs that let e-health applications exchange health data with French hospital information systems and with healthcare professionals over the national MSSanté secure-messaging network. The platform is organised as API Services: Hospital API Services (an Identity & Encounter service giving secure access to patient administrative, coverage, encounter and appointment data inside a given hospital, and a Send-documents-to-EHR service that pushes medical documents into hospital Electronic Health Records), and National API Services (the MSS service for sending medical documents to healthcare professionals via MSSanté). Access is machine-to-machine over OAuth 2.0 client credentials, scoped by functional scopes and bound to a healthcare organisation through a database_reference. Lifen also ships an SSO/OIDC API and a signed webhook surface for patient and encounter events. The company is ISO 27001 certified and an HDS (Hebergeur de Donnees de Sante) certified health-data host.

Lifen publishes 7 APIs on the APIs.io network, including CommunicationRequest API, Coverage API, Encounter API, and 4 more. Tagged areas include Company, Healthcare, FHIR, Interoperability, and Health Data.

The Lifen catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Lifen’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 27 more developer resources.
