EPOS Now API
EPOS Now is an all-in-one cloud-based point-of-sale system that helps retail and hospitality businesses simplify sales, track stock, and grow faster. This page is an independent design exercise that asks what a well-designed EPOS Now API could look like: the resources it would expose, the authentication it would need, and the workflows it could unlock. Below: a hypothetical endpoint design, the technical requirements a production implementation would face, the use cases programmatic access could serve, and where to start if your team needs this kind of access today.
This page is an independent analysis by Supergood of what a well-designed EPOS Now API could look like. It draws on publicly available information, vendor materials, and general integration experience in this category. Nothing on this page describes an existing EPOS Now product, and Supergood is not affiliated with or endorsed by the vendor. If the vendor offers an official API, we highly recommend it.
What is EPOS Now?
EPOS Now is an all-in-one cloud-based point-of-sale system that helps retail and hospitality businesses simplify sales, track stock, and grow faster. Merchants use EPOS Now to process sales and payments, manage real-time inventory, run staff scheduling and training, surface real-time reporting on sales, margin, customers, and stock, and extend their setup through an AppStore of 100+ integrations spanning accounting, ecommerce, loyalty, scheduling, and online ordering.
Core product areas include:
- POS Hardware (Countertop, Micro, Pro+, and Duo terminals)
- Payment Solutions (Air, Link, and Pro+ card machines with integrated processing)
- Cloud POS Software (back-office management accessible from any device)
- AppStore Integrations (Shopify, Sage, QuickBooks, OpenTable, Deputy, Loyalzoo, KDS, and 100+ more)
An API for a platform like this would naturally organize around its core data entities:
- Products, Categories, Brands, Tax Rates, Product Composition
- Customers, Addresses, Customer Types, Loyalty Points, Credit
- Transactions, Transaction Items, Tenders, Discounts, Seating Areas
- Product Stock, Transfers, Purchase Orders, Suppliers, Locations
- Bookings, Booking Customers, Booking Items
- Staff, Access Rights, Clocking Records, Devices, End-of-Day Reports
The EPOS Now Integration Challenge
Merchants run daily operations on EPOS Now across retail and hospitality, but turning device- and back-office-driven workflows into reliable API automation is non-trivial:
- API Device provisioning: Access requires registering an API Device in the EposnowHQ Backoffice and gathering an access key and token before any request can be made
- Per-merchant configuration: Products, tax rates, seating areas, and staff access rights are configured per location, so generic integrations break across tenants
- Resource sprawl: Product, Customer, Transaction, Stock Control, Booking, Staff, and Reports each carry their own object models and IDs to reconcile
- Retail and hospitality differences: A grocery store's stock and pricing flows look nothing like a restaurant's bookings, seating, and KDS workflows
- Format and pagination handling: The API accepts and returns both JSON and XML, and large product, customer, and transaction sets require careful paging
- AppStore overlap: Some capabilities are brokered through AppStore partner apps rather than direct endpoints, adding indirection to integrations
What a EPOS Now API Could Look Like
If EPOS Now exposed a modern, general-purpose API, the integration challenges above suggest what it would need to get right. This is a design sketch, not documentation of anything that exists today:
- First-class authentication: session handling with support for MFA and enterprise sign-on where the platform uses them
- Consistent resources: normalized JSON schemas and pagination across the platform's core objects
- Reliable writes: idempotency keys and validation that mirrors the platform's own workflow rules
- Entitlement awareness: endpoints scoped to what each customer's licensing actually permits
The endpoint sketches, technical requirements, and use cases below flesh out this hypothetical design.

Potential API Endpoints
Authentication
/authenticateWould authenticate to an EPOS Now account using API Device access key and token credentials and obtain a session for downstream calls.
Products
/productsWould list products with categories, brands, tax rates, and composition, filtered by location, category, and status.
Products
/create_productWould create a new product with pricing, tax rate, category, and stock settings for a given location.
Transactions
/transactionsWould retrieve transactions with items, tenders, discounts, and seating area details across date ranges and devices.
Customers
/customersWould pull customer profiles, addresses, types, loyalty points, and credit balances.
Stock Control
/stockWould read product stock levels, transfers, purchase orders, and suppliers across locations.
Use Cases
Sync sales and transactions into your warehouse
- Pull transactions, items, tenders, and discounts from every location into a single warehouse - Stream sales and margin data to downstream BI and finance tools - Reconcile end-of-day and daily sales reports against accounting systems
Keep products and inventory in sync
- Push product, pricing, and tax-rate updates into EPOS Now from a central catalog - Pull real-time stock levels, transfers, and purchase orders for replenishment - Surface low-stock and supplier events to ordering workflows
Unify customer and loyalty data
- Sync customer profiles, addresses, and types into your CRM - Reconcile loyalty points and credit balances across locations - Trigger marketing and retention workflows on new or returning customers
Automate hospitality bookings and staff workflows
- Pull bookings, booking customers, and booking items for reservation systems - Sync staff profiles, access rights, and clocking records to scheduling and payroll - Route seating and booking changes to KDS and front-of-house tools
Connect via No-Code Tools
Automate this platform from the no-code stack you already use.
Technical Requirements
Authentication
Would require API Device access key and token credentials with managed session handling
Connectivity
Would build on EPOS Now REST API plus authenticated Backoffice flows where direct endpoints are not exposed
Response format
Normalized JSON across Products, Customers, Transactions, Stock Control, Bookings, and Staff objects (XML also supported upstream)
Rate limits
Adaptive throttling tuned to your account to avoid EPOS Now-side limits
Session management
Would need automatic session refresh, credential rotation, and access-key handling
Data freshness
Near real-time pulls for transactions, stock, and customers with optional scheduled batch syncs
Security
Encrypted credential vault, scoped access tokens, SOC 2-aligned controls, and audit logging
Webhooks
Event-style callbacks for new transactions, stock changes, customer updates, and bookings
Latency
Design target: sub-second reads on cached entities; multi-second writes when posting products and stock adjustments
Throughput
Design target: horizontally scaled workers sized to multi-location retail and hospitality volume
Reliability
Retry, backoff, and idempotency keys for product, stock, and transaction writes
Versioning
Clear versioning and change management would matter as EPOS Now evolves
Frequently asked questions
Yes. Products, stock, transactions, and staff are pulled and reconciled across every location on your account, with per-location configuration preserved rather than flattened into a generic schema.
Availability of official interfaces varies by product, plan, and licensing. Many platforms in this category gate access behind partner programs or paid modules, and there is often no broadly available, self-serve public API. Check the vendor's developer resources for current offerings.
The hard parts would be authentication (MFA, session management, enterprise controls), consistent schemas across the platform's products, and write semantics that reconcile the way the platform's own workflows do.
