[SOLVED] Configuring PayPal Express Checkout

I am trying to configure my website with PayPal and the extension won't work with the Quick Setup which brings up a 404 error in the minibrowser so in the manual config it is asking for an API Username, API Password and API Signature - however when I have gone into my PayPal account, all I can find is PayPal Account Name, Client ID and Secret. Are these the 3 fields that I need to configure it?

Many thanks

OK, found it - for PayPal express it's in the Business account details on the main page of PayPal - not from the developer console pages.
