DEAR Systems (Cin7 Core) API

Frequently asked questions
DEAR Systems (Cin7 Core) scores D on the API Report Card. Cin7 Core publishes two parallel REST APIs, V1 and V2, documented on Apiary and the help center. Auth is two custom headers, an account ID plus an application key created in-app. Webhooks require the paid Automation module, and rate limit numbers are unpublished despite tight throttling.
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.
DEAR Systems is a cloud inventory, order management, and light-ERP platform now sold as Cin7 Core after Cin7 acquired DEAR in June 2021.
Primary bucket: misc (Inventory & Order Management / SMB ERP). A wholesale brand or light manufacturer connects Shopify, Amazon, and a B2B portal as sales channels, imports product/SKU/variant data into Cin7 Core, and configures multi-warehouse locations, reorder points, and supplier records.
Mid-to-high inside the SMB inventory/ERP niche. Cin7 publicly cites 8,500+ customers across the combined Core + Omni product lines processing 125M+ orders annually and $35B+ in sales.
Cin7 Core is the system of record for on-hand quantities, lot/serial tracking, BOMs and work orders, multi-warehouse transfers, B2B wholesale pricing, sales orders, purchase orders, invoices, and the bidirectional sync between sales channels (Shopify, Amazon, WooCommerce, eBay, BigCommerce, Square POS) and the accounting GL (QuickBooks Online, Xero).
DEAR Systems was founded in 2012 (Sydney, Australia) and was a contemporary of TradeGecko and Unleashed.
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 DEAR Systems (Cin7 Core) API and MCP server so AI agents and internal tools can read and write DEAR Systems (Cin7 Core) data. See the DEAR Systems (Cin7 Core) integration docs at supergood.ai/docs/dear-systems-cin7-core-api.
