API Signature versus Certificate

[uchca]

I already have a API Signature set up through PAY PAL. Pay Pal informed me that I can only have one API Signature and the one I am trying to place in my online store through ShopSite is not working.

Your ShopSite API set up calls for a CERTIFICATE and I have a PAYPAL SIGNATURE. Can I use my PAYPAL SIGNATURE with my store?

No, you can't use the API Signature with ShopSite, you must use an API Certificate.
