Klara

Klara is a US healthcare patient-engagement and communication platform, now part of Modernizing Medicine (ModMed), that gives medical practices two-way secure messaging, patient texting, appointment reminders and scheduling, intake and forms, telemedicine, and automated workflow tools to reduce phone volume and staff workload. Klara markets integration with 50+ EHR and practice-management systems, but it does not publish its own self-serve public developer API, FHIR CapabilityStatement, or downloadable OpenAPI. Its parent, ModMed, operates a partner-gated developer program at portal.api.modmed.com covering an ONC-certified HL7 FHIR R4 API with SMART-on-FHIR (built for the 21st Century Cures Act, US Core, OAuth2, bulk NDJSON export) plus a proprietary FHIR API for the EMA and gGastro EHR/PM platforms and a Synapsys App Marketplace. That certified API surface belongs to ModMed's EHR products, not to the Klara messaging product itself. Home market is the United States.

Klara is profiled on the APIs.io network. Tagged areas include Healthcare, United States, Patient Engagement, Patient Communication, and Secure Messaging.

Klara’s developer surface includes support, engineering blog, signup flow, and 9 more developer resources.
