RLM Apparel API

RLM Apparel Software (now Aptean Apparel ERP RLM Edition) is a fully integrated ERP, PLM, and financials platform built for the fashion and apparel industry, unifying product lifecycle, sourcing, order management, inventory, production, EDI, and B2B/B2C commerce. An unofficial API lets you programmatically pull styles, orders, purchase orders, inventory, vendors, and customers—and push updates like new orders, POs, and style data back into RLM.

What is RLM Apparel?

RLM Apparel is a fully integrated apparel ERP, PLM, and financials platform built specifically for the fashion and apparel industry—now offered as Aptean Apparel ERP RLM Edition. Fashion brands and manufacturers use RLM to manage the full product lifecycle from design through manufacturing, run sourcing and supply chain collaboration, process orders from entry to fulfillment, track raw-material and finished-goods inventory, plan and control production, exchange EDI with trading partners, and sell across wholesale, retail, and e-commerce channels.

Core product areas include:

  • ERP (unified production, inventory, sales, and financials—accounting, budgeting, and reporting)
  • Product Lifecycle Management (PLM) for managing styles from inception through design and manufacturing
  • Supply Chain Management and sourcing with supplier collaboration
  • Order Management streamlining processing from order entry to fulfillment
  • Advanced Inventory Management tracking raw materials and finished goods
  • Production planning and control, EDI trading-partner communication, CRM, and multi-channel (e-commerce, wholesale, retail) sales

Common data entities:

  • Styles, Product Specs, Bills of Material, Colorways, Size Scales
  • Sales Orders, Order Lines, Allocations, Shipments, Invoices
  • Purchase Orders, Cut Tickets, Production Orders, WIP
  • Inventory (raw materials and finished goods), Warehouses, Stock Movements
  • Vendors/Suppliers, Customers, Trading Partners, EDI Documents

The RLM Apparel Integration Challenge

Apparel brands and manufacturers run mission-critical workloads on RLM daily, but turning its ERP/PLM workflows into API-driven automation is non-trivial:

  • Deployment variability: RLM ships as both traditional on-premise and hosted cloud subscription, so the available surfaces and network paths differ by customer
  • No documented public API: integration typically flows through EDI, file exports, or partner services rather than an open, self-serve REST catalogue
  • Forty-plus modules with their own object models, IDs, and lifecycle states across PLM, ERP, financials, and SCM
  • Per-brand customization: style hierarchies, size scales, allocation rules, and forms are tailored per customer, so generic integrations break across tenants
  • EDI-heavy trading-partner workflows that require careful mapping of POs, ASNs, and invoices to downstream systems
  • Authentication and session handling: portal logins and configured entitlements complicate headless automation

How Supergood Creates RLM Apparel APIs

Supergood reverse-engineers authenticated browser flows and RLM's data surfaces to deliver a resilient API layer for your RLM deployment—across PLM, order management, inventory, and financials—whether you run on-prem or the hosted cloud subscription.

  • Handles username/password and MFA (SMS, email, TOTP) securely
  • Maintains session continuity with automated refresh and change detection
  • Normalizes responses across Styles, Orders, Purchase Orders, Inventory, and Customers so you integrate once and rely on consistent objects
  • Aligns with brand-specific style hierarchies, size scales, and entitlements to ensure compliant access

Potential API Endpoints

Authentication

POST/authenticate

Authenticate to an RLM deployment using username/password, or MFA and obtain a session token for downstream calls.

Styles

GET/styles

List styles with specs, colorways, size scales, and bill-of-material data, filtered by season, status, or division.

Orders

GET/orders

Retrieve sales orders, order lines, allocations, and shipment status across wholesale, retail, and e-commerce channels.

Orders

POST/create_order

Submit a new sales order against configured customers, styles, and size scales.

Purchasing

GET/purchase_orders

Pull purchase orders, cut tickets, and production orders with vendor, status, and delivery filters.

Inventory

GET/inventory

Query raw-material and finished-goods inventory by warehouse, style, color, and size with stock movement history.

Use Cases

Sync style and product lifecycle data into downstream systems

- Pull styles, colorways, size scales, and bills of material from PLM into PIM and e-commerce platforms - Keep design-to-production status in sync across teams and suppliers - Reconcile style master data across wholesale, retail, and B2B channels

Automate order management and fulfillment

- Push new sales orders into RLM and pull allocation and shipment status back for customer notifications - Stream order, invoice, and shipment events to BI and finance systems - Route EDI POs and ASNs to and from trading partners without manual re-keying

Reconcile inventory and production across warehouses

- Sync raw-material and finished-goods inventory levels into planning and replenishment tools - Track cut tickets, production orders, and WIP against demand - Surface low-stock and overstock events to merchandising workflows

Keep vendor, customer, and financial data in sync

- Pull vendor, customer, and trading-partner records into CRM and ERP systems - Sync invoices, payments, and AR/AP from RLM financials into the general ledger - Trigger downstream workflows when purchase orders or customer terms change

Technical Requirements

Authentication

Username/password and MFA (SMS, email, TOTP) handled in a managed session

Connectivity

Authenticated browser flows plus EDI and file-export surfaces where exposed by the deployment

Response format

Normalized JSON across Styles, Orders, Purchase Orders, Inventory, and Customer objects

Rate limits

Adaptive throttling tuned to your on-prem or hosted cloud deployment to avoid server-side limits

Session management

Automatic session refresh, MFA replay handling, and credential rotation

Data freshness

Near real-time pulls for orders, inventory, and styles 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, shipment, PO status, and inventory changes

Latency

Sub-second reads on cached entities; multi-second writes when posting orders and purchase orders

Throughput

Horizontally scaled workers sized to peak-season order and EDI volume

Reliability

Retry, backoff, and idempotency keys for orders, POs, and inventory adjustments

Adaptation

Continuous monitoring of RLM releases and brand-specific configuration drift

Frequently asked questions

Yes. Supergood adapts to either model. For the hosted cloud subscription we work against your tenant; for on-prem or hybrid customers we operate against the same authenticated surfaces, with network configuration tuned to your environment.

RLM does not publish an open, self-serve REST API; integration typically flows through EDI, file exports, or partner services. Supergood builds a resilient API layer over your authenticated RLM surfaces so you can read and write programmatically.

Styles and PLM data, sales orders, purchase orders, production orders, inventory, vendors, customers, and financials are exposed through one normalized API surface, so you integrate once across ERP, PLM, and SCM.

Each deployment is profiled against its configured style hierarchies, size scales, allocation rules, and forms. Supergood preserves brand-specific fields and lifecycle states rather than forcing a generic schema.

Yes. POs, ASNs, and invoices exchanged with trading partners are mapped to the same normalized objects, so EDI-driven data sits alongside order, inventory, and style entities.
