Paladin Data Corporation API

Paladin Data Corporation builds Paladin Point of Sale, a retail POS and inventory management platform for hardware, lumber/building supply, pharmacy, feed/seed, pet, and general retail stores. An unofficial API lets you programmatically pull inventory, item pricing, stock-on-hand, customers, and sales/invoice data—and push updates like new invoices, stock adjustments, and online orders back into Paladin.

What is Paladin Data Corporation?

Paladin Data Corporation is an independent retail software provider with 45+ years of industry experience, best known for Paladin Point of Sale—a point-of-sale and inventory management platform for independent and multi-store retailers. Stores use Paladin to run checkout, manage inventory and pricing, process purchase orders, connect to distributor EDI networks, and bridge in-store and online sales.

Core product families:

  • Paladin Point of Sale (flagship POS and inventory management for hardware, lumber/building supply, pharmacy, feed/seed, pet, and general retail)
  • PaladinGo (mobile point of sale for selling from anywhere on the floor)
  • PaladinShop (e-commerce storefront synced to in-store inventory)
  • PaladinMSP (managed services and cybersecurity for retail environments)
  • Distributor EDI connections (Ace Hardware, Do it Best, True Value, Orgill, Bostwick-Braun, United Hardware, and others)

Common data entities:

  • Items, Part Numbers, Descriptions, Pricing, Stock-on-Hand
  • Invoices, Sales Transactions, Line Items, Tenders
  • Purchase Orders, Receivings, Vendors, EDI Catalogs
  • Customers, Accounts, Loyalty, Charge Balances
  • Stores, Registers, Inventory Adjustments, Online Orders

The Paladin Data Corporation Integration Challenge

Retailers run daily operations on Paladin, but turning a Windows-based, store-deployed POS into API-driven automation is non-trivial:

  • eCommerce-scoped API surface: Paladin's published eCommerce API focuses on inventory reads, invoice creation, and stock-on-hand updates—broader operational data often lives only inside the POS UI
  • Store-deployed installs: Paladin runs on in-store Windows systems, so headless access and multi-store rollups require careful session and connectivity handling per location
  • Partner/portal gates: API access and credentials are provisioned through Paladin's client portal and support, requiring setup before integrations go live
  • Vertical-specific data: Hardware, lumber, pharmacy, and feed/seed stores carry different item attributes, units of measure, and EDI catalogs—generic mappings break across verticals
  • EDI and distributor coupling: Pricing, catalogs, and purchase orders flow through Ace, True Value, Orgill, and Do it Best EDI feeds that must reconcile with local inventory
  • Stock and pricing consistency: Online orders, in-store sales, and inventory adjustments must stay in sync to avoid overselling and price drift

How Supergood Creates Paladin Data Corporation APIs

Supergood reverse-engineers authenticated Paladin sessions and the eCommerce API surface to deliver a resilient, normalized API layer over your Paladin Point of Sale deployment—across single-store and multi-store operations.

  • Handles Paladin credentials and portal-provisioned API access securely in a managed session
  • Maintains session continuity with automated refresh and change detection across store installs
  • Normalizes items, pricing, stock-on-hand, invoices, and orders so you integrate once across verticals and stores
  • Reconciles EDI catalogs and distributor feeds with local inventory to keep pricing and stock consistent
