To make booking confirmations more secure, we are improving the way information is shared. Starting in January, detailed data such as balancing groups, booked capacity, and capacity type will no longer appear directly in the confirmation email.

Instead, each confirmation will contain a short summary and a direct link to the respective booking on the platform. This ensures sensitive information stays protected, while you can still access all booking details quickly and easily — just as before. 

Ahead of these changes, we’ll host a webinar to guide you through the new format, show how to access details on the platform, and answer your questions. Look out for the registration link in this newsletter in the coming months.

We’re confident these updates will strengthen data security while keeping your processes simple and familiar.

From 29 September onwards, the Shipper API and UI will allow Transport Auction Surcharge Values with up to eight digits after the decimal point.

Any additional digits will be automatically truncated, not rounded.

This ensures more consistent and precise allocation calculations across the platform.

No implementation changes are required on your side.

If you have any questions, our team is happy to support you.
