Every Google service has at least one API that can be used to access it. These are disabled by default (since there are hundreds – Gmail, Maps, Pub/Sub, …) They must be manually enabled before anyone in your project can use them.
Enabling the following 3 will be enough for most interactions with Pitt-Google resources. Follow the links, make sure you’ve landed in the right project (there’s a dropdown in the blue menu bar), then click “Enable”:
If/when you attempt a call to an API you have not enabled, the error message provides instructions to enable it. You can also search the API Library.
