The Restaurant API Built for Modern Online Ordering
GrubStack API is a headless, multi-tenant REST API that powers menu management, order processing, and location data for food service businesses. Built on Python and Flask, it serves as the data backbone for every GrubStack application.
Everything your restaurant stack needs from an API
GrubStack API handles the complex data layer so you can focus on building great customer experiences. From authentication to order fulfilment, every capability is exposed through clean, documented endpoints.
RESTful API Architecture
Versioned REST endpoints built on Python and Flask. Every resource — menus, orders, locations, and users — is accessible through a consistent, predictable API surface.
JWT Authentication
Stateless, token-based authentication protects every endpoint. Role-based access control ensures tenants can only interact with their own data.
Multi-Tenant by Design
Built from the ground up for Software as a Service. Each customer operates in full isolation using PostgreSQL Row-Level Security, with zero cross-tenant data leakage.
Menu & Catalog Management
Full CRUD operations for menus, categories, items, modifiers, and variants. Build complex menu structures that power the storefront in real time.
Order Processing Engine
Accept, track, and fulfil orders across multiple channels. The order pipeline handles status transitions, timestamps, and fulfilment data end to end.
Multi-Location Support
Manage multiple store locations under a single tenant account. Each location has its own hours, menus, and settings while sharing a unified data model.
Built for developers and restaurant operators alike
Whether you are a developer integrating GrubStack into a larger ecosystem or a restaurant operator running the full GrubStack suite, the API is designed to be consumed easily and extended without friction. Its headless architecture means your frontend is completely decoupled — swap, extend, or rebuild the customer experience without touching a line of backend logic.
