On previous Stripe Dashboard, you can view the API, either the test and live publishable and secret key on one page.

On the current Dashboard, I got confused why I couldn't see the live API key.

The reason why was because I keep clicking the "View test data" toggle which shows the Test API key everytime I clicked the API menu. I need to click teh "View test data" as I was checking the Events and Logs on the website I was testing.

 

So if you want to view the Live API publishable and secret key, make sure the "View test data" is off.
