Boulevard is a client experience platform purpose-built for appointment-based self-care businesses - hair salons, spas, medspas, barbershops, and nail salons. The platform covers self-scheduling, CRM, marketing, payments (as a certified PayFac), and reporting. Boulevard exposes its integration surface as GraphQL - a Client API for building custom booking experiences and an Admin API for syncing business operations data (clients, appointments, staff, locations, memberships, gift cards) - plus a separate Tokenization API for PCI-scope-reducing card capture. API access is gated to the Enterprise tier and provisioned through a developer sandbox (business ID + API key) via the Boulevard Developer Portal.
