+# Resource: claims_mapping_policy
+
+Manages a Claims Mapping Policy within Azure Active Directory.
+
+## API Permissions
+
+The following API permissions are required in order to use this resource.
+
+When authenticated with a service principal, this resource requires the following application roles: `Policy.ReadWrite.ApplicationConfiguration` 
+
+When authenticated with a user principal, this resource requires one of the following directory roles: `Application Administrator` or `Global Administrator`
+
+## Example Usage
+
+```terraform
+resource "azuread_claims_mapping_policy" "test" {
+  definition = [
+    jsonencode(
+      {
+        ClaimsMappingPolicy = {
+          ClaimsSchema = [
+            {
+              ID            = "employeeid"
+              JwtClaimType  = "name"
+              SamlClaimType = "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name"
+              Source        = "user"
+            },
+            {
+              ID            = "tenantcountry"
+              JwtClaimType  = "country"
+              SamlClaimType = "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/country"
+              Source        = "company"
+            }
+          ]
+          IncludeBasicClaimSet = "true"
+          Version              = 1
+        }
+      }
+    ),
+  ]
+  description  = "hcl-created-policy"
+  display_name = "hcl-create-policy"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `definition` - (Required) The claims mapping policy. This is a JSON formatted
+  string, for which the [`jsonencode()` function](https://www.terraform.io/language/functions/jsonencode)
+  can be used.
+* `description` - (Required) The description for this Claims Mapping Policy.
+* `display_name` - (Required) The friendly name for this Claims Mapping Policy.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The ID of the Claims Mapping Policy.
+
+## Import
+
+Claims Mapping Policy can be imported using the `id`, e.g.
+
+```shell
+terraform import azuread_claims_mapping_policy.id 00000000-0000-0000-0000-000000000000
+```
