Unleashed API
Unleashed documents a broad REST API with webhooks, a sandbox, and a full developer portal. Every request is HMAC-SHA256 signed, credentials go only to the account owner, and monthly call quotas follow your subscription tier. PUTs blank any omitted fields, forcing GET-merge-PUT cycles.
Frequently asked questions
Unleashed scores C on the API Report Card. Unleashed documents a broad REST API with webhooks, a sandbox, and a full developer portal. Every request is HMAC-SHA256 signed, credentials go only to the account owner, and monthly call quotas follow your subscription tier. PUTs blank any omitted fields, forcing GET-merge-PUT cycles.
Unleashed has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
Unleashed Software is a cloud inventory management and light-ERP platform headquartered in Auckland, New Zealand, with offices in the UK and US.
Primary bucket: misc (Cloud Inventory Management / Light ERP / SMB MRP). A SMB manufacturer or wholesale distributor connects Xero or QuickBooks Online (or Access Financials) for the general ledger, and Shopify/WooCommerce/Amazon/BigCommerce/eBay for sales channels.
Unleashed is a Tier-1 brand inside the SMB cloud-inventory niche but is not a category-definer at the Shopify/QuickBooks/NetSuite level.
Yes, for any SMB manufacturer or wholesale distributor running Unleashed, the platform is the system of record for nearly every operational dataset that drives revenue, fulfillment, and the GL.
Founded in 2009 in Auckland, New Zealand, Unleashed was a contemporary of TradeGecko, DEAR Systems, and Cin7, and is one of the original cloud-native inventory ERPs from the ANZ SaaS wave.
No partial-update semantics, every PUT must include all fields or the omitted fields are blanked out; integrators must GET-then-merge-then-PUT for every edit, multiplying API call usage and introducing race conditions. Monthly API-call quota tied to subscription tier, when usage hits the cap, all API calls fail until either the 1st of the next month or a paid 'API Extra Usage Bundle' is added, creating mid-month integration outages.

Common alternatives include Cin7 Core (ex-DEAR Systems), Cin7 Omni, Katana Cloud Inventory, Fishbowl Inventory, Zoho Inventory, MRPeasy. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Unleashed API and MCP server so AI agents and internal tools can read and write Unleashed data. See the Unleashed integration docs at supergood.ai/docs/unleashed-api.
