Square for Restaurants API

Overview

Square for Restaurants is the restaurant-specific layer of Square's broader commerce platform, used by quick-service restaurants, fast-casual operators, food trucks, bars, and growing multi-location brands that run payments and POS on Square infrastructure. The product adds table management, floor plan configuration, multi-course service workflows, and restaurant-specific reporting on top of Square's core payments and catalog stack. Square has the largest installed base of any POS system in the US small-business segment, which makes Square for Restaurants a recurring integration requirement for restaurant-tech companies whose target customer base skews toward independent operators and emerging chains.

Unlike most POS platforms, Square has a well-documented public REST API with self-serve access. The API covers orders, catalog items, payments, and locations, and there is no partner approval process to reach production credentials. The practical gap is not access — it is coverage and the managed-service layer. Restaurant-specific data that the Square for Restaurants product layer generates — floor plan configurations, course management structures, dining-room-level views, and certain reporting aggregations — is not fully surfaced through the public API surface. Teams building against the public API also carry their own operational burden: when Square updates internal endpoints or modifies session behavior, integrations break without warning, and there is no SLA-backed maintenance service to heal them.

Integuru generates a production-ready HTTP API for Square for Restaurants using direct HTTP requests against the authenticated endpoints the Square web application uses for its own POS, reporting, and management views. The eight planned actions cover orders, menu structure, payments, location configuration, and sales summaries, with 24/7 on-call maintenance on the Production plan so your team does not carry the integration reliability burden as Square's platform evolves.

Part of this is already live. The Square integration has 14 verified actions covering the Square Dashboard's reconciliation, transactions, discounts and voids reports, transaction listing by business day, the catalogue, and daily labor, tips and timecard cuts per location. If that is the data you need, start there. This guide covers the restaurant-specific layer the live page does not: order detail with modifiers and course assignments, full menu structure, floor plan and dining-room configuration, and the sales aggregations the Square for Restaurants product adds on top.

Why Teams Need This Integration

Square's public API covers much of the foundation, but specific categories of restaurant-tech product consistently need what it does not.

Restaurant analytics and AI operations platforms. Tools that pull order and payment data to power sales forecasting, menu performance analytics, and AI-driven staffing recommendations need list_orders and list_payments on a reliable, high-frequency schedule. The public API's rate limits and the absence of a managed maintenance SLA create reliability risk for production workloads. An analytics platform that breaks when Square updates an endpoint and has to wait for its own engineering team to diagnose and fix the issue is not delivering the uptime its restaurant customers expect.

Menu management and multi-channel ordering systems. Online ordering platforms, delivery aggregators, and ghost kitchen operators that sync menus across channels need list_menu_items and get_menu to stay synchronized with Square as the item catalog system of record. Square for Restaurants adds course assignments and modifier structures on top of the base catalog API, and that additional layer is not consistently available through the public API. A multi-channel ordering platform serving Square for Restaurants locations needs the complete catalog structure, not just the base catalog API subset.

Food cost and invoice management platforms. Back-office platforms that reconcile POS sales against food cost and invoices need get_sales_summary on a daily schedule aligned to the restaurant's business day close. Square's aggregated reporting views include breakdowns by daypart, item category, and dining type that the public API does not fully expose but that food cost platforms use to match sales against ingredient-level cost data.

Franchise and multi-unit reporting tools. Restaurant groups running multiple Square locations need consolidated payment records and sales summaries across their portfolio for daily P&L visibility and period-end reconciliation. list_payments and get_sales_summary feed these consolidated views, and the 24/7 maintenance guarantee means a Square update at midnight does not show up as missing data in the morning report.

Restaurant Workflows This Integration Covers

The eight planned actions cover the order, menu, payment, location, and sales data surfaces that restaurant-tech products need from Square for Restaurants:

• Order data: list_orders and get_order_detail deliver paginated order records and full per-order detail including line items, modifiers, discounts, taxes, tips, and tender records for analytics platforms, AI operations tools, and reconciliation workflows.
• Menu data: list_menu_items and get_menu surface the item catalog and full menu structure with categories, modifier lists, tax mappings, and course assignments for online ordering systems, delivery aggregators, and menu management platforms.
• Location data: list_locations and get_location_detail provide the location roster and per-location configuration including hours, payment capabilities, and dining room settings for multi-unit reporting tools and franchise management platforms.
• Payment data: list_payments delivers paginated payment records with tender type, amount, fees, and order reference for finance reconciliation systems and multi-location payment analytics tools.
• Sales reporting: get_sales_summary delivers aggregated daily sales figures including gross sales, net sales, refunds, discounts, and taxes collected for food cost platforms and franchise P&L dashboards.

Adjacent Integrations

Integuru already operates across the restaurant and food service vertical in production. The SpotOn integration delivers 9 live actions covering customer listing, settlements, net sales reporting, location management, employee data, and order retrieval for restaurant POS and payments workflows. The Aloha integration provides 4 live actions covering store listing, check search, check detail retrieval, and daily DDV report retrieval for enterprise restaurant POS operators. The Resy integration covers 2 live actions for venue listing and reservation retrieval for reservation management workflows. The MarginEdge integration provides 2 live actions covering order detail and order listing for restaurant food cost and invoice management platforms. All four use the same direct HTTP architecture and 24/7 on-call maintenance model that the Square for Restaurants integration will follow.
