Cin7 API
Cin7 ships two separate REST APIs, Core (formerly DEAR) and Omni, each with its own portal, auth model, and endpoint set. Both use static key pairs generated in-app rather than OAuth. Coverage spans products, orders, and stock with webhooks, but rate-limit caps are unpublished.
Frequently asked questions
Cin7 scores D on the API Report Card. Cin7 ships two separate REST APIs, Core (formerly DEAR) and Omni, each with its own portal, auth model, and endpoint set. Both use static key pairs generated in-app rather than OAuth. Coverage spans products, orders, and stock with webhooks, but rate-limit caps are unpublished.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Cin7 is an inventory and order management platform sold as two distinct products on a shared brand: Cin7 Core (the rebranded DEAR Systems product, positioned as the out-of-the-box inventory/ERP for SMB product businesses) and Cin7 Omni (the original Cin7 product, positioned as the more customizable mid-market platform with deeper B2B, EDI, and 3PL workflows).
Primary vertical bucket: misc (Inventory Management / Order Management / SMB-to-Mid-Market). A multichannel seller or wholesale distributor sets up SKUs with variants, UOMs, reorder points, vendor mappings, and BOMs in Cin7; configures multiple warehouses, bins, and locations; and connects QuickBooks Online or Xero plus sales channels (Shopify, Amazon, WooCommerce, BigCommerce, eBay, Walmart, Magento) and shipping (FedEx, UPS, USPS, DHL via ShipStation, Starshipit, Shippo).

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 Cin7 API and MCP server so AI agents and internal tools can read and write Cin7 data. See the Cin7 integration docs at supergood.ai/docs/cin7-api.
