Shopify POS API
Shopify POS is the in‑store point‑of‑sale experience that connects to your Shopify store, letting retailers sell in person while syncing inventory, customers, orders, discounts, and payments across locations. An unofficial API lets you programmatically pull POS orders with tender brea
What is Shopify POS?
Shopify POS is a point‑of‑sale solution built for retail merchants using Shopify. It centralizes product catalogs, pricing/discounts, inventory across locations, customer profiles, in‑person checkout, receipts, returns/exchanges, and payment processing—while staying in sync with the online store for omnichannel operations like BOPIS, local delivery, and ship‑to‑customer.
Core product areas include:
- Sales & Checkout (POS Orders, Line Items, Discounts, Taxes, Receipts)
- Inventory & Locations (Products/Variants, Stock Levels, Transfers, Stocktakes)
- Customers & Loyalty (Profiles, Tags, Gift Cards, Store Credit)
- Staff & Registers (Roles/Permissions, Devices, Shifts, Cash Drawer)
- Omnichannel (BOPIS, Local Delivery, Returns/Exchanges, Pickup/Delivery Status)
Common data entities:
- Stores, Locations, Registers/Devices
- Staff (users, roles, permissions)
- Products/Variants (SKUs, barcodes, pricing)
- Inventory Levels (per location), Stock Movements (sales, returns, adjustments)
- POS Orders (line items, discounts, taxes, tenders, receipts)
- Customers (profiles, tags, purchase history)
- Gift Cards and Store Credit (issuance, balances, redemptions)
- Shifts (open/close, cash counts, discrepancies)
The Shopify POS Integration Challenge
Retail teams rely on Shopify POS daily, but turning POS‑first workflows into API‑driven automation has known friction:
- POS‑specific data gaps: Tender breakdowns (cash vs card vs gift card), shift/register cash counts, and device metadata aren’t fully exposed via official APIs
- Gift cards & store credit: Gift card API access historically requires certain plans (e.g., Plus), and store credit/exchange flows are not straightforward to model
- Offline mode: POS can operate offline; reconciling cached sales with online data requires careful change detection
- Multi‑location complexity: Inventory accuracy depends on location‑aware adjustments, transfers, and returns; naive updates cause stock drift
- Receipts & exchanges: Receipt artifacts and exchange line items are optimized for front‑end flows, complicating headless automation
- Rate limits & cost: Admin API limits and plan restrictions can hinder high‑volume exports, real‑time dashboards, and automation at scale

Frequently asked questions
Supergood supports workflows across commonly used modules such as POS Orders (tenders, receipts), Inventory & Locations (levels, adjustments), Customers (profiles, tags), Gift Cards/Store Credit (issuance, balances), and Registers/Shifts (cash reconciliation), subject to your licensing and entitlements. We scope coverage during integration assessment.
We support username/password + MFA (SMS, email, TOTP). Sessions are refreshed automatically with secure challenge handling and store selection.
Yes. We normalize cash, card, gift card, and store credit tenders at the order and shift levels and can deliver summarized batches to ERP/accounting (e.g., QuickBooks, Xero) while complying with rate and permission constraints.
We can retrieve balances, redemptions, and issuance workflows where your plan permits and model store credit for exchanges. Some official gift card endpoints are plan‑restricted; we handle these constraints case‑by‑case.
