The Digital Container Shipping Association (DCSA) has announced the release of version 2.2 of its Track & Track Interface Standard for customer-facing events, freely available for use by industry stakeholders wishing to exchange data with its container line members.
The new release includes the DCSA Subscription Callback API, allowing customers (shippers/consignees) to subscribe to receive automatic updates of shipment events from carriers. In addition, security has been enhanced with subscription-ID and notification-signature headers.
The updated version also supports more efficient data inquiry and handling, including support for the following document events: Cargo Survey, Customs Inspection, Verified Gross Mass, Dangerous Goods Declaration, and Out of Gauge Declaration.
The API definitions and reference implementation have been updated and can be downloaded from SwaggerHub, with the new reference implementation available on GitHub. All accompanying documents and a web glossary of terms can be downloaded for free on the DCSA website.
DCSA is a neutral, non-profit group founded by major ocean carriers to digitise and standardise the container shipping industry. Member carriers include: MSC, Maersk, CMA CGM, Hapag-Lloyd, ONE, Evergreen, Yang Ming, HMM and ZIM.
