The plugin allows you to toggle between the test and live modes.
You can use Test Mode for testing and checking the payment process in your store. Once you’re ready to accept real-time payments, you can go through the Live Mode.
You can use the active and test modes to communicate with Stripe.
If you have enabled the test mode in your store, the orders will be processed through your test secret key.
However, if you have enabled the live mode in your store, then real payments will be completed through the live secret key.
