aid: 3plcentral url: https://raw.githubusercontent.com/api-evangelist/3plcentral/refs/heads/main/apis.yml name: 3PL Warehouse Manager kind: company description: 3PL Warehouse Manager is the flagship cloud warehouse management system (WMS) built for third-party logistics providers, now sold under Extensiv and historically known as "3PL Central". Its public integration surface is the SecureWMS REST API (base https://secure-wms.com), used to create and retrieve orders, manage items and inventory, read stock summaries and stock details, submit and track inbound receivers (ASN), and enumerate customers, warehouses/facilities, and locations. Authentication is OAuth 2.0 client-credentials against https://secure-wms.com/AuthServer/api/Token, returning a short-lived bearer token (typically valid 30-60 minutes). This entry documents the 3PL Warehouse Manager / SecureWMS API specifically; the broader Extensiv company (which also spans Order Management, Integration Manager, Fulfillment Marketplace, and Warehouse Analytics) is tracked complementarily under the all/extensiv company entry. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Warehouse Management - WMS - 3PL - Logistics - Fulfillment - Inventory - Orders - SecureWMS - Extensiv created: '2026-07-04' modified: '2026-07-04' specificationVersion: '0.19' apis: - aid: 3plcentral:3plcentral-orders-api name: 3PL Warehouse Manager Orders API tags: - Orders - Fulfillment - Outbound image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://developer.3plcentral.com/ baseURL: https://secure-wms.com properties: - url: https://developer.3plcentral.com/ type: Documentation - url: https://developer.extensiv.com/pages/3pl-wareshouse-manager.html type: APIReference - url: openapi/3plcentral-openapi.yml type: OpenAPI - url: collections/3plcentral.postman_collection.json type: PostmanCollection - url: collections/3plcentral.opencollection.json type: OpenCollection description: Create, retrieve, and list outbound orders in 3PL Warehouse Manager - the most common use of the SecureWMS API.
