This API enables the functionality to support the Inventory Linking Export process. Inventory Linking controls and monitors cargo moving through temporary storage facilities, and allows the movement/transition through frontiers.

There are three functional areas;

  • Consolidation This enables the combining of consignments into one master consignment, or splitting into multiple consignments.
  • Movement Records the movement of consignments within Customs controlled storage facilities.
  • Query The querying of data held within the Inventory Linking Export database.

Within each of these functional areas, there are multiple message types, each performing a specific activity.



You can use the HMRC Developer Sandbox to test the API. The Sandbox is an enhanced testing service that functions as a simulator of HMRC’s production environment.

Note: The Customs Inventory Linking Exports API is user restricted. For some message types, the person who grants authority to the software must be authorised for that functionality. This means that you must generate an authorised test user if you want to test all the functionality. Use the Create Test User API to generate the test user, passing an appropriate EORI from the CDS Test Data Library. You can download the CDS Test Data Library from the CDS Technical Documentation.

Why do these endpoints look different?

The endpoints for this API now use the Open API Specification (OAS).

The API has not changed. You do not need to make any updates to your application if you already use this API.
