inFlow API
inFlow is a cloud inventory and order management platform used by 50,000+ businesses for stock tracking, sales and purchase orders, barcode scanning, manufacturing, and B2B wholesale. An API lets you programmatically pull products, sales orders, purchase orders, customers, vendors, stock levels, and locations—and push updates like new orders, stock adjustments, and product changes back into inFlow.
What is inFlow?
inFlow is a cloud inventory and order management platform from Archon Systems used by 50,000+ businesses as an accessible alternative to complex ERP systems and spreadsheets. Teams use inFlow to track stock levels across locations, manage sales and purchase orders, scan barcodes and print labels, build assemblies and kits, and run B2B wholesale and field-service operations—syncing with ecommerce, accounting, and shipping platforms.
Core product areas include:
- inFlow Inventory (core inventory, sales, purchasing, and order management)
- inFlow Stockroom (mobile barcode scanning for stock in/out and counts)
- inFlow Manufacturing (assembly and kit-building on top of the core platform)
- B2B Showroom portal, warehouse and wholesale management, and asset tracking
- inFlow Pay, hardware (Smart Scanner, portable label printer), and 95+ ecommerce, accounting, and shipping integrations
Common data entities:
- Products (costs, default pricing, vendor items, inventory lines)
- Sales Orders, Purchase Orders, and order lines
- Customers and Vendors
- Stock and Inventory Lines (quantities by location)
- Locations, Categories, and Pricing Schemes
The inFlow Integration Challenge
Businesses run daily fulfillment, purchasing, and stock workflows on inFlow, but wiring it into broader automation has friction:
- Paid API add-on gate: API access requires an active subscription plus the API add-on, and keys are generated per company from the Integration page
- Company-scoped base URL: every call is namespaced under {companyId}, so multi-account or partner setups need per-tenant key handling
- Single-copy keys: API keys can only be copied once at creation, complicating secret rotation and recovery
- Cursor pagination and includes: results page in small batches (default 20) using before/after entityId cursors with nested include statements that must be assembled correctly
- Mobile and middleware data: barcode scans, B2B Showroom, and many platform syncs route through Stockroom apps or Extensiv/Zapier middleware rather than direct API surfaces
- No published rate limit or webhook contract: the docs do not specify rate limits or event webhooks, so polling and throttling must be handled defensively
How Supergood Creates inFlow APIs
Supergood wraps inFlow's REST API and authenticated app flows to deliver a resilient, normalized integration layer for your company account—handling key management, pagination, and related-object expansion so you integrate once.
- Manages API key and companyId authentication in a secure managed session, including single-copy key handling and rotation
- Resolves cursor pagination, count sizing, filters, and nested include statements automatically
- Normalizes responses across products, orders, stock, and locations so you integrate against consistent objects
- Adds change detection and synthetic event callbacks where inFlow exposes no native webhooks

Frequently asked questions
Yes. inFlow's API requires an active subscription plus the API add-on, and a key generated per company from the Integration page. Supergood manages that key and companyId for you in a secure session once it's provisioned.
Core inventory objects: products with cost and pricing, sales orders, purchase orders, customers, vendors, stock and inventory lines, and locations. Supergood normalizes these into consistent objects you can read and write.
inFlow does not publish a native webhook contract. Supergood adds change detection and synthetic event callbacks so you receive near real-time notifications for order, product, and stock changes without polling everything yourself.
The API pages results in small batches (default 20) using before/after entityId cursors, with include statements for nested objects. Supergood resolves cursors, count sizing, filters, and includes automatically so you get complete, consistent result sets.
Yes. The API supports reading and writing data, so you can create sales orders, update products, post stock adjustments, and manage purchase orders. Supergood adds retry, backoff, and idempotency to keep writes safe.
