YouTube Analytics API: How to enter key | Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup - api

Question

I am using this sample code for my YouTube analytics API:
(function() {
// Retrieve your client ID from the {{ Google Cloud Console }} at
// {{ https://cloud.google.com/console }}.
var OAUTH2_CLIENT_ID = 'YOUR_CLIENT_ID';
var OAUTH2_SCOPES = [
'https://www.googleapis.com/auth/yt-analytics.readonly',
'https://www.googleapis.com/auth/youtube.readonly'
];
var ONE_MONTH_IN_MILLISECONDS = 1000 * 60 * 60 * 24 * 30;
// Keep track of the currently authenticated user's YouTube channel ID.
var channelId;
// For information about the Google Chart Tools API, see:
// https://developers.google.com/chart/interactive/docs/quick_start
google.load('visualization', '1.0', {'packages': ['corechart']});
// Upon loading, the Google APIs JS client automatically invokes this callback.
// See http://code.google.com/p/google-api-javascript-client/wiki/Authentication
window.onJSClientLoad = function() {
gapi.auth.init(function() {
window.setTimeout(checkAuth, 1);
});
};
// Attempt the immediate OAuth 2.0 client flow as soon as the page loads.
// If the currently logged-in Google Account has previously authorized
// the client specified as the OAUTH2_CLIENT_ID, then the authorization
// succeeds with no user intervention. Otherwise, it fails and the
// user interface that prompts for authorization needs to display.
function checkAuth() {
gapi.auth.authorize({
client_id: OAUTH2_CLIENT_ID,
scope: OAUTH2_SCOPES,
immediate: true
}, handleAuthResult);
}
// Handle the result of a gapi.auth.authorize() call.
function handleAuthResult(authResult) {
if (authResult) {
// Authorization was successful. Hide authorization prompts and show
// content that should be visible after authorization succeeds.

loadAPIClientInterfaces();

// authorization and hide content that should be visible if authorization
// succeeds.

When I insert in the client ID, it says this:
Daily Limit for Unauthenticated Use Exceeded. Continued use requires
signup.
I researched this, and it means I have to also put in the API Key. Where do I do this?
Thanks,
Ben

Before
gapi.auth.authorize
put
gapi.client.setApiKey(API_KEY);
