This method is used to retrieve a list of validation error messages (or, more generally, validation messages) that can be utilized in communication with the CPL API. It is primarily used so that the application employing the interface knows:
Which error (or warning) codes may occur during calls to other API methods (e.g., when creating a shipment, validating inputs, generating labels, etc.).
The textual representation of a specific error code (typically available in multiple languages, most commonly Czech and English).
The recommended troubleshooting steps or a detailed description of the error (sometimes provided as part of the message, while in other cases the code is intended solely for programmatic handling).
