Creating access control lists (acl.xml)

The app/code/Foggyline/Helpdesk/etc/acl.xml file is where we define our module access control list resources. Access control list resources are visible under the Magento admin System | Permissions | User Roles area, when we click on the Add New Role button, as shown in the following screenshot:

Looking at the preceding screenshot, we can see our Helpdesk Section under Stores | Settings | Configuration. How did we put it there? We have defined it in our app/code/Foggyline/Helpdesk/etc/acl.xml file with content as follows:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Acl/ etc/acl.xsd">
    <acl>
        <resources>
            <resource id="Magento_Backend::admin">
                <resource id="Magento_Customer::customer">
                    <resource id="Foggyline_Helpdesk:: ticket_manage" title="Manage Helpdesk Tickets"...
