Wherefour API

Wherefour is a cloud manufacturing and distribution ERP that unifies lot-level inventory, production, traceability, and compliance for food, beverage, cannabis, chemical, and other regulated manufacturers. An unofficial API lets you programmatically pull lots, inventory, orders, work orders, recipes/formulas, purchase orders, and suppliers—and push updates like new orders, production batches, and inventory adjustments back into Wherefour.

What is Wherefour?

Wherefour is a cloud manufacturing and distribution ERP that unifies lot-level inventory, production tracking, traceability, and compliance for growing manufacturers. Companies use Wherefour to manage inventory with FIFO/FEFO/LIFO tracking, run work order-driven production with COGS visibility, trace materials forward and backward for recall readiness, manage purchasing and suppliers, and sync orders and journal entries to accounting—serving food & beverage, cannabis, chemicals, nutraceuticals, breweries, pet food, and other regulated industries.

Core product areas include:

Inventory Management (lot-level visibility, FIFO/FEFO/LIFO tracking)
Production & Work Orders (work order-driven workflows, COGS/COGM tracking)
Traceability & Recall Readiness (forward and backward material tracking)
MRP & Forecasting, Purchasing & Supplier Management
Warehouse Management and B2B Customer Ordering Portal
Compliance (document storage, COAs/SOPs, Metrc for cannabis)
Sales/CRM, Ecommerce Automation, and Accounting sync

Common data entities:

Lots, Inventory Items, Locations, Adjustments
Sales Orders, Invoices, Credit Memos, Shipments
Work Orders, Production Batches, Recipes/Formulas (BOMs)
Purchase Orders, Suppliers/Vendors, Receipts
Customers, Compliance Documents (COAs, SOPs), Traceability Records

The Wherefour Integration Challenge

Manufacturers run mission-critical production and traceability on Wherefour daily, but turning its portal and configuration-driven workflows into reliable API-driven automation is non-trivial:

REST API surface variability: Wherefour exposes a REST API (JSON) and Zapier connector, but endpoint coverage and field shapes vary by module and account configuration
Lot and traceability granularity: Forward/backward genealogy, FIFO/FEFO/LIFO consumption, and split lots require precise handling to keep recall-readiness data intact
Industry-specific configuration: Apparel, cannabis, food & beverage, and chemical accounts model recipes, units, and compliance documents differently, so generic integrations break across tenants
Authentication and session handling: API keys and authenticated sessions must be managed securely for headless, scheduled automation
Accounting and EDI sync coupling: COGS/COGM journal entries, invoices, and SPS Commerce EDI documents must stay consistent across QuickBooks, Xero, Sage Intacct, and Dynamics
Compliance document workflows: COAs, SOPs, and Metrc manifests need careful upload/download and association with the right lots and batches

How Supergood Creates Wherefour APIs

Supergood reverse-engineers authenticated browser flows and Wherefour's REST API surface to deliver a resilient, normalized API layer for your Wherefour account—across inventory, production, purchasing, and compliance.

Handles API key and username/password authentication, including MFA, in a managed session
Maintains session continuity with automated refresh and change detection
Normalizes responses across lots, inventory, orders, work orders, recipes, and purchase orders so you integrate once and rely on consistent objects
Preserves lot genealogy, units of measure, and industry-specific custom fields to keep traceability and compliance data accurate

API Endpoints

Authentication

POST/authenticate

Authenticate to a Wherefour account using an API key or username/password and obtain a session token for downstream calls.

Inventory

GET/inventory

List inventory items and lots with filters for location, status, expiration, and FIFO/FEFO/LIFO consumption order.

Inventory

POST/create_adjustment

Post an inventory adjustment or lot movement with reason codes and location, preserving lot genealogy.

Orders

GET/orders

Retrieve sales orders, invoices, and shipment status with customer, date range, and fulfillment filters.

Production

POST/create_work_order

Create a work order from a recipe/formula (BOM), consuming component lots and producing finished-goods lots with COGS.

Purchasing

GET/purchase_orders

Pull purchase orders, supplier records, and receipts to reconcile incoming inventory and supplier performance.

Use Cases

Sync inventory and lot traceability to a data warehouse

- Pull lots, inventory levels, and locations into a central warehouse for analytics - Stream lot genealogy and consumption events to recall-readiness and quality tools - Reconcile on-hand quantities against accounting and ecommerce channels

Automate production and work order workflows

- Create work orders from recipes/formulas and consume component lots programmatically - Capture COGS/COGM and finished-goods lots back into downstream reporting - Trigger production scheduling and MRP forecasts without portal clicks

Reconcile orders, invoices, and accounting

- Sync sales orders, invoices, and credit memos to QuickBooks, Xero, Sage Intacct, or Dynamics - Push COGS journal entries and match receipts against purchase orders - Surface delinquent or unshipped orders to fulfillment and AR workflows

Centralize purchasing and compliance documents

- Pull purchase orders, suppliers, and receipts for spend and supplier-performance reporting - Attach COAs, SOPs, and Metrc manifests to the correct lots and batches - Keep compliance documentation in sync with audit and recall workflows

Frequently asked questions

Yes. Supergood preserves forward and backward lot genealogy, FIFO/FEFO/LIFO consumption order, and split-lot relationships so your recall-readiness and traceability data stays intact through the API.

Not necessarily. Where Wherefour's REST API or Zapier connector is exposed, Supergood uses it; otherwise we work against authenticated sessions, so you get consistent coverage regardless of which surfaces your account exposes.

Yes. Supergood can pull and push orders, invoices, credit memos, and COGS journal entries that align with QuickBooks, Xero, Sage Intacct, Microsoft Dynamics, and SPS Commerce EDI workflows.

Each account is profiled against its configured recipes, units of measure, and compliance documents. Supergood preserves industry-specific fields—including Metrc manifests for cannabis and COAs/SOPs for food and chemicals—rather than forcing a generic schema.

Yes. You can create work orders from recipes/formulas, consume component lots, and record finished-goods lots with COGS/COGM, all through the normalized API surface.
