DEAR Systems (Cin7 Core) API
DEAR Systems, now branded as Cin7 Core, is a cloud-based inventory and order management platform that gives product businesses real-time visibility across suppliers, warehouses, and sales channels in one unified system. This page is an independent design exercise that asks what a well-designed DEAR Systems (Cin7 Core) API could look like: the resources it would expose, the authentication it would need, and the workflows it could unlock. Below: a hypothetical endpoint design, the technical requirements a production implementation would face, the use cases programmatic access could serve, and where to start if your team needs this kind of access today.
This page is an independent analysis by Supergood of what a well-designed DEAR Systems (Cin7 Core) API could look like. It draws on publicly available information, vendor materials, and general integration experience in this category. Nothing on this page describes an existing DEAR Systems (Cin7 Core) product, and Supergood is not affiliated with or endorsed by the vendor. If the vendor offers an official API, we highly recommend it.
What is DEAR Systems (Cin7 Core)?
DEAR Systems, now branded as Cin7 Core, is a cloud-based inventory and order management platform that gives product businesses real-time visibility across suppliers, warehouses, and sales channels in one unified system. Customers use it to run purchasing and supplier management, multi-location warehouse operations, assembly and advanced manufacturing with bills of materials, multichannel sales across e-commerce, POS, and B2B portals, and to sync financials with accounting platforms like Xero and QuickBooks Online.
Core product areas include:
- Inventory Management (real-time stock tracking across multiple locations and 3PLs)
- Purchasing (supplier management, purchase orders, and order automation)
- Warehouse Management (multi-location operations, pick/pack/ship)
- Sales Channels (e-commerce, POS, and B2B portal integration)
- Manufacturing (assembly and advanced production planning with Bill of Materials)
- Accounting integration (Xero and QuickBooks Online) plus reporting and analytics
An API for a platform like this would naturally organize around its core data entities:
- Products, Product Families, Categories, Brands, Bills of Materials
- Product Availability, Stock Adjustments, Stocktakes, Transfers
- Sales, Sale Orders, Fulfilments, Invoices, Sale Credit Notes
- Purchases, Purchase Orders, Receipts, Supplier records
- Customers, Suppliers, Locations, Chart of Accounts
- Assemblies, Disassemblies, and advanced Production runs
The DEAR Systems (Cin7 Core) Integration Challenge
Product businesses run mission-critical inventory and order workflows on Cin7 Core daily, but building reliable automation against it carries real friction:
- Per-application credentials: The official API requires an Account ID and Application key (api-auth-accountid / api-auth-applicationkey) generated per company, so multi-tenant access means juggling many credential pairs
- Per-application rate limits: API throttling is applied per Application key, so high-volume sync jobs across products, sales, and stock can hit limits without careful pacing
- API version drift: V1 and V2 coexist with different coverage and field shapes, and migration to V2 is recommended, integrations must track which surface exposes which entity
- Deep object graphs: Sale and Purchase orders span quotes, orders, fulfilments, invoices, and credit notes, each with their own statuses and line items that must be stitched together
- Stock accuracy and effective timing: Product availability, stock adjustments, transfers, and assemblies move inventory in real time, so reads and writes must respect ordering and idempotency
- Accounting coupling: Because Cin7 Core syncs to Xero and QuickBooks, financial entities like invoices and credit notes carry downstream consequences that automation must handle carefully
- Manufacturing complexity: BOM-driven assemblies and advanced production introduce component-to-finished-goods relationships that generic connectors often flatten incorrectly
What a DEAR Systems (Cin7 Core) API Could Look Like
If DEAR Systems (Cin7 Core) exposed a modern, general-purpose API, the integration challenges above suggest what it would need to get right. This is a design sketch, not documentation of anything that exists today:
- First-class authentication: session handling with support for MFA and enterprise sign-on where the platform uses them
- Consistent resources: normalized JSON schemas and pagination across the platform's core objects
- Reliable writes: idempotency keys and validation that mirrors the platform's own workflow rules
- Entitlement awareness: endpoints scoped to what each customer's licensing actually permits
The endpoint sketches, technical requirements, and use cases below flesh out this hypothetical design.

Potential API Endpoints
Authentication
/authenticateWould authenticate to a Cin7 Core account using the Account ID and Application key headers and establish a managed session for downstream calls.
Products
/productsWould list products with families, categories, brands, and bills of materials, filtered by SKU, name, and status.
Inventory
/product_availabilityWould retrieve real-time stock-on-hand and availability across warehouses and locations.
Sales
/create_saleWould create a sale order with line items, customer, fulfilment, and invoice details against the account's configuration.
Purchasing
/purchasesWould pull purchase orders, receipts, and supplier records with status and date-range filters.
Inventory
/create_stock_adjustmentWould post a stock adjustment to correct on-hand quantities for products at a given location.
Use Cases
Sync inventory and availability across channels
- Pull product, product availability, and stock adjustment data from Cin7 Core into a central warehouse - Stream stock-on-hand changes to e-commerce, marketplace, and BI tools in near real time - Reconcile transfers and stocktakes across multiple locations and 3PLs
Automate sales order and fulfilment workflows
- Push new sale orders, fulfilments, and invoices into Cin7 Core from external storefronts - Pull sale credit notes and order statuses back for finance and customer-service tools - Route fulfilment and shipping events without manual portal clicks
Reconcile purchasing and supplier data
- Sync purchase orders, receipts, and supplier records into procurement and AP systems - Match received quantities against purchase orders for three-way reconciliation - Surface backorders and late deliveries to replenishment workflows
Connect manufacturing and BOM data
- Pull bills of materials, assemblies, and production runs for planning and costing tools - Trigger assemblies and disassemblies as component stock changes - Track finished-goods output back against forecast and demand signals
Connect via No-Code Tools
Automate this platform from the no-code stack you already use.
Technical Requirements
Authentication
Would require cin7 Core Account ID and Application key (api-auth-accountid / api-auth-applicationkey) with managed session handling
Connectivity
Would build on cin7 Core external API (V1 and V2) plus authenticated browser flows where the public API does not expose an entity
Response format
Normalized JSON across Products, Sales, Purchases, Stock, Customers, and Suppliers
Rate limits
Adaptive pacing tuned to Cin7 Core's per-Application-key limits to avoid throttling
Session management
Would need automatic credential handling, key rotation, and re-authentication
Data freshness
Near real-time reads for stock, sales, and purchases with optional scheduled batch syncs
Security
Encrypted credential vault, scoped access keys, SOC 2-aligned controls, and audit logging
Webhooks
Event-style callbacks for sale, purchase, fulfilment, and stock-level changes
Latency
Design target: sub-second reads on cached entities; multi-second writes when posting orders and stock adjustments
Throughput
Design target: horizontally scaled workers sized to multichannel order and inventory volume
Reliability
Retry, backoff, and idempotency keys for sale orders, purchase orders, and stock movements
Versioning
Clear versioning and change management would matter as DEAR Systems (Cin7 Core) evolves
Frequently asked questions
Yes. Assemblies, disassemblies, advanced production, and bills of materials are exposed through the same normalized surface, so manufacturing data sits alongside inventory and order entities.
Availability of official interfaces varies by product, plan, and licensing. Many platforms in this category gate access behind partner programs or paid modules, and there is often no broadly available, self-serve public API. Check the vendor's developer resources for current offerings.
The hard parts would be authentication (MFA, session management, enterprise controls), consistent schemas across the platform's products, and write semantics that reconcile the way the platform's own workflows do.
