  title: Open Dental Accounts & Ledger Patients API
  description: 'REST API for Open Dental dental practice management software. The web service is hosted at Open Dental headquarters and lets approved third-party applications read and write practice data on behalf of Open Dental customers. Requests authenticate with a per-application Developer Key and a per-customer Customer Key, sent together in a single header as "Authorization: ODFHIR {DeveloperKey}/{CustomerKey}". The full published specification documents 130+ resource groups; this document models a representative, load-bearing subset. The paths under Patients, Appointments, Providers, ProcedureLogs (Procedures), Claims, and Payments are grounded in the published per-resource reference pages and are marked CONFIRMED below. The remaining resource groups (Accounts/Ledger, Fees & Fee Schedules, Recalls, Documents, Medications & Prescriptions, Referrals, Sheets) follow Open Dental''s standard REST CRUD convention and are marked MODELED - verify exact paths and fields against the live spec before use. A separate local API Service (talks to the on-premises Open Dental program without routing through Open Dental servers) and a FHIR interface also exist and are out of scope for this document.'
