----
+=== Permission Evaluation Operation
+
+The `evaluatePermission` operation allows you to evaluate authorization
permissions for a user or service account using Keycloak's Authorization
Services. This operation uses the Keycloak Authorization Client (AuthzClient)
to request permissions and obtain a Requesting Party Token (RPT) with granted
permissions.
+
+NOTE: This operation requires Authorization Services to be enabled on the
client in Keycloak.
+
+==== Configuration Requirements
+
+The `evaluatePermission` operation requires the following configuration:
+
+* `serverUrl` - Keycloak server URL
+* `realm` - Keycloak realm name
+* `clientId` - Client ID with authorization services enabled
+* `clientSecret` - Client secret (required for AuthzClient)
+
+==== Modes of Operation
+
+The operation supports two modes:
+
+1. **RPT Mode** (default): Returns a Requesting Party Token (RPT) containing
the granted permissions
+2. **Permissions-Only Mode**: Returns only the list of permissions without
obtaining an RPT token
+
+==== Response Format
+
+**RPT Mode** (default, `permissionsOnly=false`):
+
+[source,json]
+----
+{
+ "token": "eyJhbGciOiJSUzI1NiIs...",
+ "tokenType": "Bearer",
+ "expiresIn": 300,
+ "refreshToken": "eyJhbGciOiJIUzI1NiIs...",
+ "refreshExpiresIn": 1800,
+ "upgraded": true
+}
+----
+
+**Permissions-Only Mode** (`permissionsOnly=true`):
+
+[source,json]
+----
+{
+ "permissions": [
+ {
+ "resourceId": "resource-id-123",
+ "resourceName": "documents",
+ "scopes": ["read", "write"]
+ }
+ ],
+ "permissionCount": 1,
+ "granted": true
+}

+==== Usage Examples
+

+// Evaluate all permissions for a user
+Map<String, Object> headers = new HashMap<>();

+====
+
+==== Authorization Patterns
+
+===== Fine-Grained Resource Authorization
+
+[source,java]
+----
+// Check if user can access a specific document
+public boolean canAccessDocument(String accessToken, String documentId) {
+ Map<String, Object> headers = new HashMap<>();
+ headers.put(KeycloakConstants.ACCESS_TOKEN, accessToken);
+ headers.put(KeycloakConstants.PERMISSION_RESOURCE_NAMES, documentId);
+ headers.put(KeycloakConstants.PERMISSION_SCOPES, "view");
+ headers.put(KeycloakConstants.PERMISSIONS_ONLY, true);
+
+ Map<String, Object> result = template.requestBodyAndHeaders(
+ "keycloak:authz?operation=evaluatePermission", null, headers,
Map.class);
+
+ return Boolean.TRUE.equals(result.get("granted"));
+}
+
+// Check multiple resources at once
+public Map<String, Boolean> checkMultipleResources(String accessToken,
List<String> resourceIds) {
+ Map<String, Boolean> accessMap = new HashMap<>();
+
+ for (String resourceId : resourceIds) {
+ accessMap.put(resourceId, canAccessDocument(accessToken, resourceId));
+ }
+
+ return accessMap;
+}
+----
+
+===== Token Exchange for Delegation
+
+[source,java]
+----
+// Evaluate permissions on behalf of another user (token exchange)
+Map<String, Object> headers = new HashMap<>();
+headers.put(KeycloakConstants.SUBJECT_TOKEN, userToken); // The user's token
+headers.put(KeycloakConstants.PERMISSION_RESOURCE_NAMES, "admin-resource");
+headers.put(KeycloakConstants.PERMISSIONS_ONLY, true);
+
+// Service evaluates if the user (from subject token) can access the resource
+Map<String, Object> result = template.requestBodyAndHeaders(
+ "keycloak:authz?serverUrl=http://localhost:8080&realm=myrealm";
+ +
"&clientId=service-client&clientSecret=secret&operation=evaluatePermission",
+ null, headers, Map.class);
+----
+
+==== Error Handling
+
+The operation throws exceptions in the following cases:
+
+* `IllegalArgumentException` - When required configuration is missing
(serverUrl, realm, clientId, clientSecret)
+* `AuthorizationDeniedException` - When the user doesn't have permission to
access the requested resources
+
+[source,java]
+----
+import org.keycloak.authorization.client.AuthorizationDeniedException;
+
+onException(AuthorizationDeniedException.class)
+ .handled(true)
+ .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(403))
+ .setHeader("Content-Type", constant("application/json"))
+ .transform().constant("{\"error\": \"Permission denied\", \"message\":
\"User lacks required permissions\"}");
+
+onException(IllegalArgumentException.class)
+ .handled(true)
+ .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(400))
+ .log("Configuration error: ${exception.message}");
+----
+
+==== Keycloak Setup for Authorization Services
+
+To use the `evaluatePermission` operation, you must configure Authorization
Services in Keycloak:
+
+1. **Enable Authorization** on the client:
+ - Go to **Clients** → Your client → **Settings**
+ - Enable **Authorization**: `ON`
+ - Save the client
+
+2. **Create Resources**:
+ - Go to **Clients** → Your client → **Authorization** → **Resources**
+ - Create resources representing protected entities (e.g., "documents",
"reports")
+
+3. **Create Scopes** (optional):
+ - Go to **Authorization** → **Scopes**
+ - Create scopes like "read", "write", "delete"
+
+4. **Create Policies**:
+ - Go to **Authorization** → **Policies**
+ - Create policies (role-based, user-based, time-based, etc.)
+
+5. **Create Permissions**:
+ - Go to **Authorization** → **Permissions**
+ - Link resources, scopes, and policies together
+
=== Bulk Operations
Bulk operations allow you to perform multiple operations in a single request,
improving efficiency and reducing network overhead. These operations are
particularly useful for provisioning, migrations, and large-scale
administrative tasks.
