  title: Phorest Third-Party Appointments Courses API
  description: The Phorest API exposes a partner-gated business's salon/spa data - clients, appointments, bookings, staff, services, products, purchases, vouchers, loyalty, and reporting - for approved integrators. Access is granted by Phorest support on request (quoting a Phorest Account Number), not through self-service signup. Requests use HTTP Basic authentication with a `global/{email}` username and a Phorest-issued API password, and are scoped in the URL path to a `businessId` and, for most resources, a `branchId`. Endpoints, methods, and parameters in this document are transcribed from Phorest's public API reference at developer.phorest.com/reference; a small number of item-level paths (marked in their description) are modeled by convention from the confirmed collection-level siblings because Phorest's public reference does not expose every single-resource path in plain text.
