Unleashed API

Unleashed is a cloud inventory management platform that unifies purchasing, warehouse operations, manufacturing, and multichannel sales for growing product businesses. An unofficial API lets you programmatically pull products, stock on hand, sales orders, purchase orders, suppliers, customers, and assemblies—and push updates like new sales orders, purchase orders, stock adjustments, and production assemblies back into Unleashed.

What is Unleashed?

Unleashed is a cloud-based inventory management platform that unifies purchasing, warehouse operations, manufacturing, and sales processes for growing businesses. Product businesses use Unleashed to track real-time stock across multiple locations, manage purchase and sales orders, run bill-of-materials production and assemblies, handle batch and serial tracking, and sync inventory with accounting and eCommerce tools through 30+ pre-built integrations.

Core product areas include:

  • Inventory Management (real-time stock tracking, barcode scanning, batch and serial number tracking)
  • Order Management (multichannel sales orders, customer pricing, sales quotes)
  • Production (Bill of Materials, assemblies, disassemblies, cost tracking)
  • Purchasing (automated purchase orders, supplier management, landed costs, purchase receipting)
  • Warehouse Operations (multi-location inventory, picking, packing, transfers with bin management)
  • Reporting & Analytics, B2B eCommerce, and integrated CRM & sales tools

Common data entities:

  • Products, Product Groups, Product Brands, Units of Measure
  • Stock On Hand, Warehouses, Stock Adjustments, Warehouse Stock Transfers
  • Sales Orders, Sales Shipments, Credit Notes, Invoices
  • Purchase Orders, Suppliers, Supplier Returns, Landed Costs
  • Assemblies, Bills of Materials, Batch Numbers, Serial Numbers
  • Customers, Customer Delivery Addresses, Companies, Currencies, Taxes

The Unleashed Integration Challenge

Distributors and manufacturers run mission-critical operations on Unleashed daily, but turning its data into reliable API-driven automation has real friction:

  • HMAC signature auth: Every request must be signed with an HMAC-SHA256 signature over the query string using the account's API key, and a wrong signature simply returns 403 Forbidden
  • Owner-only credentials: API ID and Key are available only to the account owner, gating programmatic access behind admin setup
  • No partial updates: The API does not support partial updates—you must pass every field on a write or risk overwriting existing data with blanks
  • Pagination handling: List endpoints page results, so syncing large catalogs and order histories means iterating PageNumber/PageSize across every resource
  • Editable vs read-only split: Some resources are editable while others (Stock On Hand, Invoices, Batch Numbers, Suppliers) are read-only, so write workflows must route through the correct entities
  • Dual-format payloads: Requests accept JSON or XML via Content-Type/Accept headers, adding serialization edge cases for integrators

How Supergood Creates Unleashed APIs

Supergood handles Unleashed's HMAC-signed authentication, pagination, and write-time constraints to deliver a resilient, normalized API layer for your Unleashed account—across inventory, orders, purchasing, and production.

  • Manages api-auth-id and HMAC-SHA256 signing per request so you never hand-roll signatures
  • Handles full-record writes automatically, fetching current state and merging so partial updates don't blank fields
  • Paginates list endpoints transparently and normalizes JSON responses across Products, Stock, Orders, and Assemblies
  • Maintains session continuity with automated retries, backoff, and change detection across Unleashed releases

API Endpoints

Authentication

POST/authenticate

Authenticate to an Unleashed account using the api-auth-id and an HMAC-SHA256 signature derived from your API key for downstream calls.

Products

GET/products

List products with filters for product code, group, brand, and modified-since, including units of measure and pricing.

Inventory

GET/stock_on_hand

Retrieve real-time stock on hand across warehouses, with batch and serial detail where tracked.

Sales

POST/create_sales_order

Create a sales order with customer, line items, pricing, and delivery address, passing all required fields.

Purchasing

GET/purchase_orders

List purchase orders with supplier, status, and date filters, including landed costs and receipting detail.

Production

POST/create_assembly

Create a production assembly against a bill of materials, consuming component stock and producing finished goods.

Use Cases

Sync inventory and stock across systems

- Pull products, stock on hand, and warehouse levels into a central warehouse or data platform - Stream stock adjustments and transfers to downstream BI and replenishment tools - Reconcile batch and serial numbers across locations for accurate availability

Automate order-to-fulfillment workflows

- Push new sales orders from eCommerce and CRM into Unleashed without portal clicks - Pull sales shipments and credit notes back for fulfillment and finance reconciliation - Route invoices and customer delivery addresses to downstream accounting

Streamline purchasing and supplier data

- Generate purchase orders from reorder points and push them into Unleashed - Sync suppliers, supplier returns, and landed costs into procurement systems - Track receipting status to keep stock and AP in sync

Connect production and assemblies

- Create assemblies against bills of materials and pull cost tracking for reporting - Sync finished-goods output and component consumption to demand planning - Surface production status to sales and inventory dashboards

Technical Specifications

Authentication

api-auth-id plus HMAC-SHA256 signature over the query string using your API key, handled in a managed session

Connectivity

Unleashed REST API at api.unleashedsoftware.com with signed requests, supplemented by authenticated flows where needed

Response format

Normalized JSON across Products, Stock, Sales, Purchasing, and Production objects (Unleashed returns JSON or XML)

Rate limits

Adaptive throttling tuned to your account to stay within Unleashed-side limits

Session management

Automatic per-request signature generation, credential rotation, and 403 retry handling

Data freshness

Near real-time pulls for stock, orders, and purchasing with optional scheduled batch syncs

Security

Encrypted credential vault, scoped access, SOC 2-aligned controls, and audit logging

Webhooks

Event-style callbacks for stock changes, order creation, shipments, and purchase receipting

Latency

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

Throughput

Horizontally scaled workers sized to multi-warehouse catalog and order volume

Reliability

Retry, backoff, and full-record writes so no-partial-update constraints never blank fields

Adaptation

Continuous monitoring of Unleashed API changes, resource availability, and account configuration drift

Frequently asked questions

Supergood manages the api-auth-id header and generates a fresh HMAC-SHA256 signature over each request's query string using your API key, so you never hand-roll signatures or debug 403 Forbidden responses.

Unleashed itself does not support partial updates—you must send every field. Supergood fetches the current record and merges your changes so writes never overwrite existing data with blank values.

Editable resources include Sales Orders, Purchase Orders, Products, Assemblies, Stock Adjustments, Credit Notes, and Stock Transfers. Read-only resources like Stock On Hand, Invoices, Suppliers, and Batch Numbers are exposed through the same normalized API surface.

Supergood transparently iterates the Unleashed pagination object (PageNumber, PageSize, TotalResults) so you receive complete result sets for products, orders, and other list endpoints without managing paging yourself.

Unleashed API ID and Key credentials are only available to the account owner. Once provisioned, Supergood operates against those credentials securely, with no further owner involvement required for day-to-day calls.
