 It's called "authorized" access because the user must give the application direct authorization to use personal data. Simple web-based applications using JavaScript usually get this authorization the way this example does: by displaying button for the user to click. This action triggers a call to a Google auth server, which pops up a standard authorization dialog. For details, see the [Authentication page](auth.md).
 
-**Note:** Here we use `gapi.load('client:auth2', ...)` to load both the `client` module (for dealing with API requests) and the `auth2` module (for dealing with OAuth 2.0) upfront. The `gapi.client.init` fuction lazily loads `auth2` if it is needed. If you are sure your app needs auth, loading the two modules `'client:auth2'` together before you call `gapi.client.init` will save one script load request.

If you are sure your app needs auth, loading the two modules `'client:auth2'` together before you call `gapi.client.init` will save one script load request.
 
 To make `gapi.client.init` set up OAuth correctly, you would have to assign the `clientID` variable the client ID generated when you registered your application (for instructions see [Integrating Google Sign-In into your web app](https://developers.google.com/identity/sign-in/web/sign-in)). The other parameter is `scope`, which in this case is just the scope for user profile permission.
 
 When the user clicks **Authorize**, the `gapi.auth2.getAuthInstance().signIn()` function is called, which shows user a popup window to let user authorize. Note that the `gapi.auth2.getAuthInstance().signIn()` can be only called from a user interaction context for most browsers (i.e. do not call it when your app starts, but call it in a button click handler).
 
-**Note:** when you authorize your application using Oauth 2.0, you do not also need to set the API key as in the first example. However, it is a good practice to do so, in case your code ever expands to handle unauthorized requests.
