        This media type integrates your Zabbix installation with your Zammad installation using the Zabbix webhook feature.
        
        Zammad configuration:
        
        1. Check that API Token Access is enabled in "Settings" → "System" → "API".
        2. Open the profile settings of the customer user and create a new Personal User Token.
        3. Set the "ticket.agent" permission for the token and press Create.
        4. Copy and save the created token somewhere, as it will be shown only once for security reasons.
        
        Zabbix configuration:
        
        1. Before you can start using Zammad webhook, set up the global macro "{$ZABBIX.URL}":
        - In the Zabbix web interface, go to "Administration" → "Macros" section in the dropdown menu in the top left corner.
        - Set up the global macro "{$ZABBIX.URL}" which will contain the URL to the Zabbix frontend. The URL should be either an IP address, a fully qualified domain name, or localhost.
        - Specifying a protocol is mandatory, whereas the port is optional. Depending on the web server configuration you might also need to append "/zabbix" to the end of URL. Good examples:
          - http://zabbix.com
          - https://zabbix.lan/zabbix
          - http://server.zabbix.lan/
          - http://localhost
          - http://127.0.0.1:8080
        - Bad examples:
          - zabbix.com
          - http://zabbix/
        
        2. Set the following webhook parameters:
        - zammad_access_token - the access token that you created during Zammad configuration
        - zammad_url - the frontend URL of your Zammad installation
        - zammad_customer - the Zammad user email
        - zammad_enable_tags - if you want to add the Zabbix event tags to the Zammad tickets that are created, you can set it to one of the following values: "1", "true", "yes", "on" (note, that if the tag support is enabled, each tag is sent via separate HTTP request and created tags will also remain in the Zammad when tickets are closed/deleted)
        - zammad_group - if needed, you can change the Zammad user group
        
        3. If you want to prioritize issues according to the severity values in Zabbix, you can define mapping parameters (create them as additional webhook parameters):
        - severity_<name> - the Zammad priority ID (<name> in the parameter name can be one of the following values: "not_classified", "information", "warning", "average", "high", "disaster")
        
        4. Create a Zabbix user and add media:
        - If you want to create a new user, go to the "Users" → "Users" section, click the "Create user" button in the top right corner. In the "User" tab, fill in all required fields (marked with red asterisks).
        - In the "Media" tab, add a new media and select "Zammad" type from the drop-down list. Add any value to the "Send to" field: it is required to be filled, but it is not used.
        - Make sure this user has access to all hosts for which you would like problem notifications to be sent to Zammad.
        
        5. Great! You can now start using this media type in actions and create tickets!
        
        You can find the latest version of this media and additional information in the official Zabbix repository:
