For many, the topic of Passar is still complex. In the following blog, we shed light on the subject and address some points and questions that we receive from users
The transition to Passar takes place in two main phases, which relate to export and import:

The most significant change for businesses will be the introduction of the new ePortal. Previously, registration in the ZKV (Customs Customer Administration) was required to obtain a certificate for communication with the customs server. In the future, this will be done via the ePortal, with communication handled using API tokens.
This change leads to incompatibility between the old and new procedures. The availability of the eVV (electronic verification document) depends on the export procedure used: with e-dec, the ZKV process remains in place, while with Passar, the eVV can only be retrieved via Chartera Output, a module of the ePortal.
The eVV from Passar differ both visually and structurally from the previous ones. They now consist of a single PDF with embedded XML, which eliminates the need to store various formats like XML, SOAP, PDF, and logs.
In summary, then:


The most important thing is registration in the ePortal. This ensures that eVV (electronic verification documents) can also be retrieved via Chartera Output. To automatically retrieve the eVV with the new procedure, it is necessary to invite the software provider and grant the corresponding rights. This way, the software provider can activate the API Self-Service.
Therefore:

Your software provider should support both procedures and ensure a seamless transition from e-dec to Passar. The exact timing of the switch to Passar is flexible, but it must take place before December 31, 2025.
Ideally, eVV exports from both procedures should be managed within a unified user interface. At Trade Monkey, we’ve implemented this as follows:

Additionally, your software provider should handle the management of API Keys, including their regular refreshing to prevent expiration.
