  title: Photon Health Clinical API
  description: >-
    Photon Health is a native GraphQL e-prescribing (eRx) platform. The entire
    Clinical API surface - patients, prescriptions, orders, the medication
    catalog, and pharmacies - is exposed through a single GraphQL endpoint at
    POST /graphql. This OpenAPI document models that single GraphQL transport
    operation; see graphql/photon-health-schema.graphql for the GraphQL schema
    and the documented queries and mutations.
