Pickware ERP API overview

The Pickware ERP API is a GraphQL API for Shopify merchants using Pickware ERP. It helps developers and agencies build custom integrations that read ERP data or run selected ERP workflows. The current 2026-06-unstable schema focuses on stock, purchasing, goods receipts, warehouses, bin locations, orders, documents, products, and supplier data.

The documentation has two parts:

• Guides explain how to work with the API and describe common merchant integration use cases.
• The API reference is generated from the GraphQL schema and documents the exact queries, mutations, fields, inputs, and required scopes.

What you can build

• Synchronize stock levels across products, warehouses, and bin locations.
• Apply stock corrections and transfer stock between bin locations.
• Create and manage supplier orders and supplier order line items.
• Maintain product-supplier configurations such as purchase prices, supplier product numbers, delivery times, and order constraints.
• Create goods receipts and move them through approval and completion.
• Manage warehouses and bin-location codes.
• Read orders represented in Pickware ERP and trigger complete shipment workflows.
• Find products and variants by product number, GTIN, or other exposed identifiers.

Where to go next

• Follow Getting started to run your first query.
• Read Authentication before calling protected operations.
• Open the Product stock use case for the stock workflow.
• Review Working with lists before building synchronization jobs.
• Read Rate limits before taking an integration into production.
• Use the API reference when you need the exact GraphQL field or input shape.

API version

The current schema is 2026-06-unstable, available at /api/2026-06-unstable. Schema versions use date-based slugs, and the -unstable suffix marks this preview as a schema that may still receive breaking changes before the first stable release. Future versions will be published as separate generated references so existing integrations can keep using the version they were built against. See Versioning for details.
