This functionality enables integration between the NEN system and the Zakázky GOV portal.
If you send a message to the contracting authority within a procurement procedure directly via the Zakázky GOV portal, the message you sent will then be available in the sent messages section in the communication system.
More information about how message sending via the Zakázky GOV portal works can be found on the Frequently Asked Questions (FAQ) page in the “Electronic communication” section.
