Yes you can use PayPal Express with the same PayPal account, but the API credentials are different than the ones for PayPal Pro.

You can get your PayPal Express API credentials by following this guide:

One thing to check with PayPal about your account and using PayPal Pro is they do require the submission of a billing agreement before you can start taking payments with PayPal Pro.
