On the CSV file you will receive three relevant information columns:

With this information Zabbix should check on the host list for the Service ID (Hostname) and react as follows:

                   a. The CSV Status information. If the status is Delivered then needs to proceed with next step. If the status is cancelled the Zabbix Host needs to be deleted.
                   b. The Host <IP address> field in order to double check if the provided by CSV file is correct. If IP Address is correct then nothing needs to be done; otherwise the Zabbix Host IP address needs to be corrected

       2. If the Host doesn't exists and CSV Status is "Delivered" then Zabbix should add the Host using a predefined template and add it to 2 Host Groups.
