I recently set up Paypal payments standard on my web app and things are working fine. I am able to use Paypal sandbox to test and things work the way I expect.
However, I would like to send out the app to my beta testers and allow them to test making payments without actually using their Paypal accounts or credit cards. I can create sandbox merchants and sandbox payees, but that doesn t quite do it. My button send them to sandbox.paypal.com... but when they get there they are asked to log in with a developer/sandbox password. It doesn t just let them login with the test payee account.
I can work around this, but I wanted to see if I was missing something.
