Square

Square organizes business by Locations (stores). Locations have Orders, Payments, Inventory, and Team Members. Customers and Loyalty are merchant-wide.

Data Model

  • Locations — physical or virtual stores; most data is location-scoped.
  • Orders — transactions; can have line items and fulfillments.
  • Payments — payment transactions.
  • Refunds — refunds on payments.
  • Customers — customer records.
  • Inventory — stock levels per location.
  • Team Members — staff; have shifts and wages.
  • Shifts — work shifts.
  • Cash Drawers — cash drawer state.
  • Loyalty — loyalty programs and rewards.
  • Bank Accounts — connected bank accounts.
  • Taxes — tax configuration.

Gotchas

  • location_id required: Most operations require a location. Enumerate locations first.
  • Idempotency: Payment and order creation support idempotency keys; use for retries.
