Release Party Integration Specifications

When an import container is commercially released, a Shipping Agent typically sends a PIN code to the Terminal and shares this code with the next party in the release chain (e.g. Forwarder, Transport Company, Beneficial Cargo Owner, …). This code, which is required to be granted access to the terminal and release the container, is distributed further in the supply chain until a party, which knows the PIN code, claims the container for pick up at the terminal.

By using the Certified Pick up (CPu) platform, a Shipping Agent will not create and distribute a PIN code to the Terminal, increasing the security of the release chain. Instead, the Shipping Agent sends the commercial release information towards the CPu platform, which vouches for a secure transfer of the “Release Right” until it is assigned to an entitled transporter to pick up the container at the terminal. The code to release the container will be sent via a secured and audited communication channel towards the Terminal.

This document describes how stakeholders of type Release Party should integrate the CPu process within their applications.


Setting up your endpoint connection

To ensure our high security standards at NxtPort, we do not allow any anonymous API connection and we require of course a minimum set of security measures to be applied on any API connection. To that end, you will need to follow the steps below to set up the secure API connection with NxtPort.

You need to have completed the steps described on Getting Started with the API integration in order to proceed.

Asynchronous processing in CPu

To correctly integrate the set of API comprehended in the CPu application, it is important to be aware of the fact that CPu mainly works in an asynchronous fashion.

This means that you when making an API call, you will not get the result to your request in the response to your API call, but NxtPort will process your request and then send you a notification through the endpoint you have configured in the Getting Started process. To that end we advise you to pay quite close attention to the use of the Public Reference Id. This is the GUID you receive in the response of your API call.

This will allow you to keep track of the notifications in line with the request calls you have made.

When a API call returns a synchronous response, it is clearly marked in this guide.

Integration API calls

General remarks

Distinct request body fields

For different actions (accept, decline, revoke etc.) you need to provide different actionType values in the request body. These different fields are highlighted under distinct request body fields in the descriptions to help you use the correct ones.

URL’s provided are PRD

The request URL’s provided are for the PRD environment. For the UAT environment, replace api.nxtport.com with api-uat.nxtport.com . Important: your API key is environment specific, so this also needs to be changed if you call our UAT environment.


Release Rights

Accept Release Right

Once another party (Ship Agent or another CPu Party) has transferred the Release Right of a container to your entity, you will receive a notification of type ReleaseRight and event Transferred. This will place the Release Right in a "queue", awaiting your acceptance or denial. It is not possible to transfer the Right of the container prior to either of these actions.

This action accepts the Release Right.

PUT https://api.nxtport.com/certified-pickup/v1/{{port_locode}}/containers/{{equipment_number}}/import/release-rights

Request headers

  • External-Reference-Id (optional): your own reference

  • Ocp-Apim-Subscription-Key: your API key

Decline Release Right

Once another party (Ship Agent or another CPu Party) has transferred the Release Right of a container to your entity, you will receive a notification of type ReleaseRight and event Transferred. This will place the Release Right in a "queue", awaiting your acceptance or denial. It is not possible to transfer the Right of the container prior to either of these actions.

This action declines the Release Right and returns it to the sender.

Transfer Release Right

In case you received and accepted a Release Right from a previous party (can be either the original Ship Agent or another Party in the supply chain), you can transfer the right to the next party in the chain.

This call allows you to transfer a Release Right to another stakeholder. As soon as the other stakeholder accepts the Right, they will hold & be able to manage the Right themselves.

When transferring a container, the transferring party is required to provide detailed information about the Release Right which he received in the previous steps. We verify if the provided information matches with the information that we have received from the original source and send via notifications to the Right owners, increasing the security about Release Right transfers.

As explained about the asynchronous handling within the CPu process, you - as a Release Party - will receive various notifications.

You will find detailed information tailored to your role in CPu on Notifications for Release Parties .
