DDI System API
DDI System is an ERP platform built specifically for wholesale distributors, delivered through its Inform ERP product and now part of Advantive. This page is an independent design exercise that asks what a well-designed DDI System 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 DDI System 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 DDI System 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 DDI System?
DDI System is an ERP platform built specifically for wholesale distributors, delivered through its Inform ERP product and now part of Advantive. Distributors use DDI System to run order fulfillment, inventory and demand forecasting, strategic pricing, embedded CRM, accounting, purchasing, warehouse management, and electronic data interchange from a single connected system, with industry-specific functionality for verticals like HVAC, janitorial sanitation, fasteners, bearings and power transmission, hose and accessories, paper and packaging, and foodservice equipment supply.
Core product areas include:
- Order Fulfillment (quote-to-order conversion, POS processing, single sales order control panel, warranty claims)
- Inventory Management & Demand Forecasting (forecast algorithms, exception management, multi-location control)
- Pricing Strategy (multi-tiered price matrices, margin-based customer pricing, vendor rebate tracking)
- Embedded CRM (360° customer visibility, contact engagement tracking, activity calendars)
- Warehouse Management (truck dispatch, cycle counting, multi-container tracking, wireless WMS)
- Financial Management, Purchasing, EDI, and eCommerce integration
An API for a platform like this would naturally organize around its core data entities:
- Sales Orders, Quotes, Invoices, POS Transactions, Warranty Claims
- Items, Inventory, Stock Levels, Multi-location Bins, Forecasts
- Customers, Contacts, Price Matrices, Customer-specific Pricing
- Purchase Orders, Vendors, Vendor Rebates, Receipts
- Shipments, Truck Dispatch Routes, Warehouse Counts, EDI Documents
- GL Accounts, Payments, Accounts Receivable/Payable
The DDI System Integration Challenge
Distributors run mission-critical operations on Inform ERP daily, but turning its screens and modules into API-driven automation is non-trivial:
- No public, self-serve developer API: integrations typically flow through web services, EDI, or partner connectors rather than openly documented REST endpoints
- Vertical-specific configuration: pricing matrices, product catalogs, and workflows are tailored per distributor and per industry, so generic integrations break across tenants
- Deployment variability: on-prem, hosted, and cloud installations differ in network access, versions, and available modules
- Complex pricing logic: multi-tiered matrices, margin rules, and vendor rebates require precise replication to avoid mis-quoting
- Authenticated session handling: portal and web-service access depends on login state and entitlements that complicate headless automation
- EDI and eCommerce sprawl: order, inventory, and pricing data must stay consistent across WMS, PIM, CRM, eCommerce, and shipping platforms
What a DDI System API Could Look Like
If DDI System 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 a DDI System / Inform ERP instance using username/password or MFA and obtain a session token for downstream calls.
Orders
/ordersWould list sales orders, quotes, and POS transactions with filters for customer, status, date range, and location.
Orders
/create_orderWould create a new sales order or convert a quote to an order, applying the distributor's pricing matrix and entitlements.
Inventory
/inventoryWould retrieve item stock levels, multi-location availability, and forecast data across the warehouse network.
Customers
/customersWould pull customer records, contacts, and customer-specific pricing from the embedded CRM.
Purchasing
/create_purchase_orderWould create a purchase order against a vendor with line items, receiving expectations, and rebate context.
Use Cases
Sync orders and inventory to eCommerce and BI
- Pull sales orders, quotes, and POS transactions from Inform ERP into a central warehouse - Stream real-time inventory and forecast data to eCommerce storefronts and BI dashboards - Reconcile multi-location stock levels across DDI System and downstream systems
Automate quote-to-order and pricing workflows
- Generate quotes using DDI System's multi-tiered price matrices and margin rules - Convert approved quotes into sales orders without portal clicks - Apply customer-specific and vendor-rebate pricing consistently across channels
Keep customer and CRM data in sync
- Push customer, contact, and engagement records between Inform ERP and external CRM - Surface customer-specific pricing and order history to sales and support tools - Trigger downstream workflows when account or contact data changes
Streamline purchasing and warehouse operations
- Create and track purchase orders against vendors and receipts - Sync truck dispatch, cycle-count, and shipment data with WMS and shipping platforms - Reconcile vendor rebates and receiving against financials
Connect via No-Code Tools
Automate this platform from the no-code stack you already use.
Technical Requirements
Authentication
Would require username/password and MFA handled in a managed, encrypted session
Connectivity
Would build on authenticated Inform ERP web flows and web-service interactions surfaced as a unified API
Response format
Normalized JSON across Orders, Inventory, Customers, Pricing, Purchasing, and Financials objects
Rate limits
Adaptive throttling tuned to your DDI System instance to avoid server-side limits
Session management
Would need automatic session refresh, MFA replay handling, and credential rotation
Data freshness
Near real-time pulls for orders, inventory, and pricing with optional scheduled batch syncs
Security
Encrypted credential vault, scoped access tokens, SOC 2-aligned controls, and audit logging
Webhooks
Event-style callbacks for order creation, inventory changes, shipment, and pricing updates
Latency
Design target: sub-second reads on cached entities; multi-second writes when posting orders and purchase orders
Throughput
Design target: horizontally scaled workers sized to high-volume distribution order and inventory traffic
Reliability
Retry, backoff, and idempotency keys for order, pricing, and inventory transactions
Versioning
Clear versioning and change management would matter as DDI System evolves
Frequently asked questions
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.
