What to do with a "success code" to Google Calendar API?

[Sam Ciz]

Hello,
I've just manage to start example file "simple.php" = Google Calendar PHP Starter Application, and I ended with my browser on page where I got some "success code", I am advised: "Please copy this code, switch to your application and paste it there: ......"
I don't know what to do with it and where to paste it in my application.

Please, can anyone help me?
Thank you!
Sam

Hey Sam,

When you created your OAuth2 client on the Google API Console, did you select "Web Application" as the application type?
