The default cart setup for PayPal only requires the primary email address used at your PayPal account profile setting. If the
Smart Checkout method is used, there must be a
Client ID created. The ID does not exist as a default so it must be done as a process.

Go to the developer area at
https://developer.paypal.com/developer/applications

- Click Create App to save.

The new App will show the Client ID. Copy the ID.
