+# Example 
+
+Policy example where the user name is encoded in base64 authentication (Basic http token)
+
+- Here user alice is granted a guest role and can perform a GET request to /productpage.
+- And user bob is granted an admin role and can perform a GET to /productpage and /api/v1/products.
+
+```
+base64_decode(YWxpY2U6cGFzc3dvcmQ=)   =  alice:password
+base64_decode(Ym9iOnBhc3N3b3Jk)       =  bob:password
+```
+
+
+Below is the example of good request payload which should pass the policy 
+```json
+{
+    "attributes": {
+        "request": {
+            "http": {
+                "method": "GET",
+                "path": "/productpage",
+                "headers": {
+                    "authorization": "Basic YWxpY2U6cGFzc3dvcmQ="
+                }
+            }
+        }
+    }
+}
+```
+
+Below is the example of bad request payload which should fail the policy
+Here alice is trying to make `GET` request on path `api/v1/products` which is not allowed.
+```json
+{
+    "attributes": {
+        "request": {
+            "http": {
+                "method": "GET",
+                "path": "/api/v1/products",
+                "headers": {
+                    "authorization": "Basic YWxpY2U6cGFzc3dvcmQ="
+                }
+            }
+        }
+    }
+}
+```
+
+Below is the example of validation policy that restricts access to an endpoint based on a user’s role and permissions.
