  title: Truepill (FuzeRx) API
  description: >-
    REST API for Truepill's pharmacy and healthcare-infrastructure platform,
    now shipping as FuzeRx after LetsGetChecked's 2024 acquisition of Truepill
    and the May 2025 rebrand to Fuze Health. The API exposes JSON over HTTPS for
    patient management, prescriptions, pharmacy-to-pharmacy transfers, insurance
    and copay adjudication, and webhook event retrieval. Endpoints and field
    names below reflect Truepill/FuzeRx public developer documentation; request
    and response bodies are summarized and should be reconciled against the live
    reference at https://rxdocs.fuzehealth.com before production use.
