  description: 'The EMA Proprietary FHIR API provides programmatic access to ModMed EMA clinical and practice-management data using FHIR R4-style resources under `/fhir/v2`.


    This documentation targets the **public sandbox** (`stage.ema-api.com`).


    **Authentication.** Two mechanisms are supported during the current migration: the **legacy OAuth2 `password` grant** (being sunset) and the **new OAuth2 `client_credentials`** flow (recommended for new integrations) — see the **Authentication** guide. Every API call also requires the `x-api-key` header.'
