Amazon Pay - Allowed return URL's; where can I find them ?

[Jeroentje]

Hello everybody,

I have installed the Amazon Pay payment method on my website (www.scarparti.com). But if you click on the Amazon - button an error appears.

The past few days I had contact with the helpdesk from Amazon. They told me to have a look in Joomla at the 'Application Log', to be more specific I have  to look at the fields "Allowed Return URLs" and "Java Script Origins". These data I have to copy to my Amazon account. Now I'm searching for these filed for quite some time now. I cannot find them... Can anyone help me to solve this issue?

Thanks in advance,
Jeroen
