Prophet 21 (Epicor) API

Prophet 21 is Epicor's cloud ERP built by distributors for distributors, running order management, inventory, warehouse, purchasing, financials, and service workloads across wholesale distribution verticals. An unofficial API lets you programmatically pull orders, customers, inventory, vendors, and financial transactions—and push updates like new orders, quotes, purchase orders, and payments back into Prophet 21.

What is Prophet 21 (Epicor)?

Prophet 21 is Epicor's cloud ERP, described as designed by distributors for distributors, combining operational management with AI-infused analytics. Wholesale distributors use Prophet 21 to run quote-to-cash order management, real-time inventory and warehouse operations, purchasing and vendor management, financials, service and maintenance, eCommerce, and CRM—across verticals like industrial, electrical, HVAC, plumbing, medical supply, fasteners, fluid power, and pipes, valves and fittings.

Core product areas include:

  • Order Management (quote-to-cash processing with integrated workflows)
  • Inventory Management (real-time stock visibility with machine-learning forecasting)
  • Warehouse Management (cloud-enabled receiving, picking, and cycle counting)
  • Purchasing (centralized procurement and vendor management)
  • Financials (real-time general ledger and financial reporting)
  • Service & Maintenance, eCommerce, CRM, and Business Intelligence (Epicor Grow)

Common data entities:

  • Orders, Quotes, Order Lines, Shipments, Invoices
  • Customers, Ship-To Locations, Contacts, Pricing, Terms
  • Inventory Items, Stock Locations, Bins, Inventory Receipts, Transfers
  • Vendors, Purchase Orders, Receipts, AP Vouchers
  • General Ledger Accounts, AR/AP Transactions, Payments
  • Service Orders, Technicians, Maintenance Schedules

The Prophet 21 (Epicor) Integration Challenge

Distributors run mission-critical workloads on Prophet 21 daily, but turning its module- and session-driven workflows into reliable API-driven automation is non-trivial:

  • Multiple API surfaces: Prophet 21 exposes a v2 metadata-driven REST API, an Entity API, an Interactive API, and an OData Data Services API—each with different scopes, semantics, and coverage
  • Session and transaction nuance: The Interactive API operates against a live Prophet 21 session, so headless automation must manage session state, business rules, and transaction sequencing
  • Cloud vs. on-prem variability: Endpoint availability, middleware, and the data dictionary differ by deployment model and Prophet 21 version
  • Authentication complexity: Distributor environments combine credentialed logins with token issuance and, increasingly, MFA—complicating unattended access
  • Deep data dictionary: Locating the right tables and columns across orders, inventory, purchasing, and financials requires navigating a large, distributor-specific schema
  • Customization per distributor: Custom fields, pricing rules, and workflow configuration vary by tenant, so generic integrations break across customers

How Supergood Creates Prophet 21 (Epicor) APIs

Supergood reverse-engineers authenticated flows and Prophet 21's native API surfaces—v2 REST, Entity, Interactive, and OData Data Services—to deliver a resilient, normalized API layer for your Prophet 21 environment, whether cloud-hosted or on-prem.

  • Handles credentialed logins, token issuance, and MFA securely in a managed session
  • Maintains session continuity for Interactive API transactions with automated refresh and change detection
  • Normalizes responses across Orders, Inventory, Purchasing, and Financials so you integrate once and rely on consistent objects
  • Aligns with distributor-specific custom fields, pricing rules, and data-dictionary mappings to ensure accurate access

Frequently asked questions

Supergood works across Prophet 21's native surfaces—the v2 metadata-driven REST API, the Entity API, the Interactive API, and the OData Data Services API—and normalizes them into a single consistent interface so you integrate once regardless of which underlying surface serves the data.

Yes. Supergood adapts to either deployment model. For Epicor-hosted cloud tenants we work against your environment's authenticated surfaces; for on-prem or hybrid distributors we operate against the same APIs with network configuration tuned to your setup.

Each environment is profiled against its data dictionary, custom fields, and pricing rules. Supergood preserves your distributor-specific schema and entitlements rather than forcing a generic model.

Yes. In addition to reads, Supergood supports writes—creating sales orders, quotes, and purchase orders with line items, pricing, and terms, with idempotency and retry handling to keep transactions safe.

The Interactive API operates against a live Prophet 21 session. Supergood manages session state, transaction sequencing, and business-rule validation automatically, so you get clean API calls without managing session lifecycle yourself.
