3PL Warehouse Manager Items API

  title: 3PL Warehouse Manager (SecureWMS) REST Authentication Items API
  description: 'REST API for 3PL Warehouse Manager, the cloud warehouse management system (WMS) for third-party logistics providers, sold under Extensiv and historically known as "3PL Central". The public integration surface is the SecureWMS REST API served from https://secure-wms.com. It is used to create and retrieve orders, manage SKU items and inventory, read stock summaries and stock details, submit and track inbound receivers (Advance Ship Notices), and enumerate customers, warehouses/facilities, and locations.


    Authentication is OAuth 2.0 client-credentials. Base64-encode "clientId:clientSecret" and POST it as a Basic Authorization header to /AuthServer/api/Token with a JSON body of {"grant_type":"client_credentials","user_login_id":<id>} (a user_login or user_login_id provided by the warehouse for auditing). The returned bearer access token is short-lived - typically valid 30 to 60 minutes - and should be refreshed at least every 30 minutes. All traffic must use HTTPS; plain HTTP is not supported.


    Collection endpoints are paged with pgnum (page number) and pgsiz (page size) query parameters and can be filtered with Resource Query Language (RQL, http://api.3plcentral.com/rels/rql) via the rql parameter and ordered with sort. Responses are HAL-style JSON where list payloads carry records under a ResourceList (or Summaries for stock summaries) property.


    Endpoint provenance: read (GET) endpoints for customers, items, inventory, stock details, stock summaries, facility locations, and orders are CONFIRMED against the public developer portal and the open-source singer-io tap-3plcentral extractor. Order creation, receiver (ASN) create/list/get, and the facilities and order-packages resources are documented in the 3PL Warehouse Manager developer portal; request/response shapes that are gated behind the authenticated developer portal are MODELED here honestly and marked per-operation with x-endpoint-status.'
