Use the CTC Traders API to:
- send departure and arrival movement notifications to the New Computerised Transit System (NCTS)
- retrieve messages sent from customs offices of departure and destination
The API endpoints relate only to Great Britain and Northern Ireland.
You can also use the HMRC sandbox environment to run tests for Great Britain and Northern Ireland transit movements.
Version 1.0 of the API supports only NCTS phase 4. Version 2.0 of the API supports only NCTS phase 5.
You can find the changelog for v2.0 of the API in the common-transit-convention-traders GitHub wiki.

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.
