List Azure role definitions

  • How-to

A role definition is a collection of permissions that can be performed, such as read, write, and delete. It's typically just called a role. Azure role-based access control (Azure RBAC) has over 120 built-in roles or you can create your own custom roles. This article describes how to list the built-in and custom roles that you can use to grant access to Azure resources.

To see the list of administrator roles for Microsoft Entra ID, see Administrator role permissions in Microsoft Entra ID.

List role definitions

To list role definitions, use the Role Definitions - List REST API. To refine your results, you specify a scope and an optional filter.

  1. Start with the following request:

    GET https://management.chinacloudapi.cn/{scope}/providers/Microsoft.Authorization/roleDefinitions?$filter={$filter}&api-version=2022-04-01

    For a tenant-level scope, you can use this request:

    GET https://management.chinacloudapi.cn/providers/Microsoft.Authorization/roleDefinitions?filter={$filter}&api-version=2022-04-01

  2. Within the URI, replace {scope} with the scope for which you want to list the role definitions.

    Scope Type
    providers/Microsoft.Management/managementGroups/{groupId1} Management group
    subscriptions/{subscriptionId1} Subscription
    subscriptions/{subscriptionId1}/resourceGroups/myresourcegroup1 Resource group
    subscriptions/{subscriptionId1}/resourceGroups/myresourcegroup1/providers/Microsoft.Web/sites/mysite1 Resource

    In the previous example, microsoft.web is a resource provider that refers to an App Service instance. Similarly, you can use any other resource providers and specify the scope. For more information, see Azure Resource providers and types and supported Azure resource provider operations.

  3. Replace {filter} with the condition that you want to apply to filter the role definition list.

    Filter Description
    $filter=type+eq+'{type}' Lists role definitions of the specified type. Type of role can be CustomRole or BuiltInRole.

    The following example lists all custom roles in a tenant:

    Request

    GET https://management.chinacloudapi.cn/providers/Microsoft.Authorization/roleDefinitions?$filter=type+eq+'CustomRole'&api-version=2022-04-01

    Response

                "assignableScopes": [
                    "/subscriptions/473a4f86-11e3-48cb-9358-e13c220a2f15"

                "permissions": [

                            "Microsoft.Billing/*/read",
                            "Microsoft.Consumption/*/read",

                            "Microsoft.Billing/invoices/download/action"
                        ],

                        ],
                        "dataActions": [],

                "updatedOn": "2021-05-22T21:57:23.5764138Z",

                "updatedBy": "68f66d4c-c0eb-4009-819b-e5315d677d70"
            },

        }

List a role definition

To list the details of a specific role, use the Role Definitions - Get or Role Definitions - Get By ID REST API.

  1. Start with the following request:

    GET https://management.chinacloudapi.cn/{scope}/providers/Microsoft.Authorization/roleDefinitions/{roleDefinitionId}?api-version=2022-04-01

    For a tenant-level role definition, you can use this request:

    GET https://management.chinacloudapi.cn/providers/Microsoft.Authorization/roleDefinitions/{roleDefinitionId}?api-version=2022-04-01

  2. Within the URI, replace {scope} with the scope for which you want to list the role definition.

    Scope Type
    providers/Microsoft.Management/managementGroups/{groupId1} Management group
    subscriptions/{subscriptionId1} Subscription
    subscriptions/{subscriptionId1}/resourceGroups/myresourcegroup1 Resource group
    subscriptions/{subscriptionId1}/resourceGroups/myresourcegroup1/providers/Microsoft.Web/sites/mysite1 Resource

  3. Replace {roleDefinitionId} with the role definition identifier.

    The following example lists the Reader role definition:
