TPN REST Communication

Onetrail TPN™ TPN is providing services in order to trade electronically by using REST. This page describes the specifications for these REST services. Onetrail TPN REST solution requires no 'Pulling' of messages. Choosing this communication, Suppliers and Buyers can POST messages to a Onetrail endpoint, and Onetrail will provide responses back to customer endpoint. It's not yet supported to collect messages from a Onetrail endpoint via REST.

Scope

The Onetrail TPN™ TPN REST for Sellers supports receiving orders, sending order status, despatch advice and invoice messages as well as handling of real-time price and availability requests. The provisioning of product-, price-, and stock data (batch) is not supported via REST, but via SOAP, FTP or email only.

The Onetrail TPN™ TPN REST for Buyers supports the real time price and availability.

Design

The Onetrail TPN™ TPN REST ODE Service for Sellers is payload agnostic, meaning the service is generic for all order related message types and thus not aware of the content of the message. Message validation (schema validation in case of XML) needs to be performed outside of the service. At this moment Onetrail TPN™ is not supporting JSON formatted messages, but only XML and EDIFACT.

...

Message definitions

Onetrail TPN™ TPN supports JSON (P&A only), XML and EDIFACT for the REST services. The documentation and definitions can be found here: Message Types

Product API
The new version of the Onetrail Product API allows for much faster and more efficient connection to the Onetrail services. It has been developed in order to reduce our footprint and maximize efficiency. Here are the ins and outs of this new Product API version.

Benefits
These are advantages of using the PnA5:

• RESTful services have a smaller footprint than SOAP, Parsing JSON is less computationally heavy and memory intensive then XML, however we can still support XML as well.
• Improved efficiency allows us to support bulk requests as well as single requests, this will allow buyers to retrieve multiple items with 1 request rather than multiple single requests.
• The health check will allow you to monitor the availability and uptime of the service.

Syntax

https://$base_url/pde/rest/v5/products?{SellerGLN}&{PDINumber}&{SellerVPN}&{GTIN}&{Quantity}&{BidID}

Example: http://prd-tpn-pna-5.cloud.onetrail.net:8088/pde/rest/v5/products?SellerGLN=8714253023236&PDINumber=C7978A

• base_url:
  • prd-tpn-pna-5.cloud.onetrail.net:8088

• Variables:
  • SellerGLN (multiple ; separated)= provide the GLN from the Seller
  • PDINumber = Onetrail TPN™ PDI number
  • SellerVPN = Seller Vendor part number
  • GTIN = Seller Global Trade Item Number (EAN)
  • Quantity = Quantity for which you want the price and availability
  • BidID = Contract ID for the price of a contract product

...

Can now handle bulk requests as well as the usual single requests. (For bulk requests the URL is:  https://rest.onetrail.net/productApi/v1/products/bulk

...

Uses basic authentication and user managed in the TPN Manager.

...

• In previous versions of Onetrail PnA, HTTP-GET, REST and SOAP requests were all valid request types. With the current version we've streamlined to accept REST requests only. There are many reasons why, but the main benefits of REST over other request types are as mentioned above: It has a smaller footprint that SOAP, can handle JSON and XML as well as other data types, it's also generally faster, more efficient and requires less bandwidth.

• Response:
  • If no Seller GLN is specified, the response will contain all products from Sellers that matches the Request of which the buyer has prices

• Remarks:
  • The JSON response is based on the PRD version 3.1 output
  • The result can contain multiple Onetrail PDI items. In that case the response will contain n-times an ns2:product element
  • The result can contain multiple Seller items per Onetrail PDI item. In that case the response will contain n-time an ns2:sellerInfo element
