Obtain Access Tokens
Google provides a Calendar API which lets you access your Google account's calendar events. Let's start by creating an Application and register it with Google's API console.
Navigate to the Google API Credentials page.
Click Create Credentials.
From the dropdown, select "OAuth client ID"
Select "TV and Limited Input devices" from the dropdown and give your client a name.
Click "Create".
Copy the Client ID and Client Secret to a text document and save it to your computer's desktop. You'll need these values later.
Next, you'll need to authorize your email address. This is a new step recently added by Google to increase the security of applications.
Navigate to https://console.cloud.google.com/apis/credentials/consent and ensure the same project from before is selected.
Name the App "MagTag Google Calendar" and use your email address in both email fields.
Click Save and Continue.
Click Add Users and add the email address belonging to the calendar you are viewing on the MagTag.
Click Save and Continue.
