First of all: I really like nopCommerce. It was easy to set up a shop, and fill it with the appropriate data.
However, I am finding it quite difficult to integrate the payment process. I have a business paypal account, and want to use direct payment. It says in the configuration panel that I need to set the shop's primary currency to USD. Why is that?
I am using a paypal business account, when I try to make a small payment into that account I get an API error, I know for sure that my credentials are correct. I am testing it without the sandbox because I want to make sure the 'live' payment is working correctly (a successfull sandbox test does not ensure it will work live :))
And also: when you go through all the payment steps, and you press confirm, you can get an error for instance that you haven't entered a correct state for the billing address. This validation is too late in my opinion, seeing that you have gone through all the other steps before.
Am i overlooking some possibillities here? Just let me now :)
Thanks in advance
By the way:
LongMessage: Security header is not valid ShortMessage: Security error ErrorCode: 10002
is the error I am getting when I use direct payment.
