+### Undefined methods
+The client will instantiate **only the instances needed** based on the provided token: if you get `undefined` method when you attempt to run a request, please check if you have all the required permissions.

 ```js
-    const cities = await client.comuni.getCitiesByCap('00132')
+const cities = await client.comuni.getCitiesByCap('00132')
 try {
 } catch(err) {
