Payflow vendor/merchant login id in paypal sandbox?

I'm trying to test in paypal's sandbox with the "PayPal Express Checkout via Payflow Pro" module.

I can't find what value I should put in the "PAYFLOW: Vendor" and "PAYFLOW: Partner" fields if I'm using a sandbox account (this is a proof-of-concept, so we don't want to set up a real Paypal account yet).

I know when I have previously used Paypal business accounts, the vendor (aka merchant) ID was found in the Paypal Manager application, but it's unclear to me whether one has access to the Paypal Manager application from within the paypal sandbox...

Any advice?

Thanks,

Okay, some better googling seems to indicate you have to set up a real payflow account to be able to fully test this: http://tinyurl.com/5ubqdq
