  title: Particle Health Authentication Projects API
  description: Particle Health is a healthcare data interoperability API that aggregates patient medical records from US health information exchanges (Carequality, CommonWell, eHealth Exchange), TEFCA / QHIN partners, state HIEs, and Surescripts. The API surfaces patient registration, asynchronous query orchestration, batch processing, document handling, network participant directory search, patient provider mapping, and real-time Signal alerting. Clinical data is returned in FHIR R4 Bundles, C-CDA documents, Flat datasets, or Deltas (incremental changes). Authentication uses OAuth 2 client-credentials with JWT bearer tokens scoped to a project.
