Skubana API
Skubana—now Extensiv Order Manager—is a multichannel order, inventory, and fulfillment management platform that centralizes ecommerce and B2B sales orders, real-time stock levels, purchasing, and shipping across sales channels like Shopify, Amazon, and eBay. An unofficial API lets you programmatically pull orders, inventory, products, shipments, purchase orders, and vendor records—and push updates like inventory adjustments, new purchase orders, and order status changes back into Skubana without per-app OAuth installs or manual exports.
What is Skubana?
Skubana—now branded Extensiv Order Manager after Skubana was acquired and consolidated into Extensiv—is a cloud-based multichannel order and inventory management platform for high-volume ecommerce sellers and brands. Operators use it to centralize ecommerce and B2B sales orders, track real-time inventory across warehouses and 3PLs, automate purchasing and replenishment, and orchestrate shipping through one-click integrations with sales channels and carriers including Shopify, BigCommerce, Magento, Amazon, eBay, Newegg, USPS, UPS, DHL, and FedEx.
Core capabilities include:
- Order Management (multichannel ecommerce and B2B order orchestration, routing, and status)
- Inventory Management (real-time stock levels, allocation, and multi-warehouse visibility)
- Purchasing & Replenishment (purchase orders, vendor management, and demand forecasting)
- Shipping & Fulfillment (carrier integrations, shipments, and 3PL routing)
- Sales channel and carrier integrations (Shopify, Amazon, eBay, BigCommerce, Magento, USPS, UPS, DHL, FedEx)
Common data entities:
- Orders, Order Items, Shipments, Returns
- Products, SKUs, Bundles/Kits, Listings
- Inventory levels, Warehouses, Stock locations, Allocations
- Purchase Orders, Vendors, Receiving records
- Sales Channels, Carrier accounts, Integrations
The Skubana Integration Challenge
Sellers run their entire fulfillment operation through Skubana, but turning that system of record into reliable, programmatic access is harder than the published API suggests:
- App-install OAuth gating: API access runs through an authorization-code flow tied to an installed app, an appKey/appSecret pair, and approved scopes—so the operator's own data is trapped behind a developer-app onboarding process
- Environment split: Production (api.skubana.com) and sandbox (api.demo.skubana.com) base URLs require separate credentials and token handling
- Per-channel data variance: Order and inventory shapes differ across Shopify, Amazon, eBay, and B2B channels, so a single normalized model has to reconcile dozens of source formats
- Inventory timing: Real-time stock levels move constantly across warehouses and 3PLs, so reads need careful freshness and reconciliation to avoid overselling
- Undocumented rate and pagination behavior: Throttling and pagination are not fully published, so naive polling risks throttles and dropped records
- Bundle and kit logic: Inventory math for kits, bundles, and multi-warehouse allocation must be preserved so downstream systems don't double-count stock
How Supergood Creates Skubana APIs
Supergood handles Skubana's OAuth authorization-code flow, app credentials, and authenticated surfaces to deliver a resilient API layer for your Extensiv Order Manager account—so your orders, inventory, and purchasing data are available without standing up and maintaining your own developer app.
- Manages the appKey/appSecret access key, authorization code exchange, and bearer-token refresh securely
- Maintains session continuity across production and sandbox environments with automated token rotation
- Normalizes orders, inventory, products, and shipments across sales channels so you integrate once against consistent objects
- Applies adaptive throttling and pagination handling tuned to avoid Skubana-side limits and dropped records

Frequently asked questions
Yes. Skubana was acquired by and consolidated into Extensiv and is now branded Extensiv Order Manager. The API still runs against the skubana.com endpoints, and Supergood supports the current platform under both names.
No. Skubana's API requires an installed app with an appKey/appSecret and OAuth authorization-code flow. Supergood handles that onboarding and token lifecycle for you, so you access your own data without standing up a developer app.
Yes. Supergood normalizes Orders, Inventory, Products, Shipments, Purchase Orders, and Vendors into one consistent surface, so multichannel order data and replenishment data sit side by side.
Supergood pulls real-time stock levels and allocations with careful freshness handling and preserves bundle, kit, and multi-warehouse logic so downstream systems don't double-count or oversell.
Yes. Supergood manages separate credentials and tokens for the production (api.skubana.com) and sandbox (api.demo.skubana.com) environments so you can test and deploy safely.
