Ok here I am again. I guess I should mention that I just did a trial run of my paypal sand box account with my zen cart with full success. I only needed to fill in three items and it just plain works. Not so with ViArt.
Now! I like the way ViArt looks and the ease of site configuration and customization. However I really don't like the PayPal Express set up you have.
Zen is nice because some stuff is easy to set up but to customize it is not quite so easy. I like them both.
If ViArt becomes as easy with shopping cart set up as Zen then I will stick with ViArt. I am torn. I really hoped that someone could and would help with the PayPal Express set up for ViArt without having to resort to sending all the info to the support crew. It should not be that difficult.
Well I did some hunting and forum searching and figured out that I had the API that accesses PayPal directly and not the API downloaded file for use on the client side. IE, my server. I closed out the original api info and did that again and got the downloadable file and set the info and it works. However I was unable to gain access to the downloadable file in PayPals Sand Box testing zone. I tried but failed. Not sure if it's paypals problem or mine. However I do have a working shopping cart.
