I'm new to nopCommerce and I'm trying to configure a payment type with the PayPal Standard plugin. Actually I'm using the paypal sandbox.
I've followed all the specified steps but I'm getting an error after the payment, when I'm redirected from paypal success payment screen to my test site. The resulting url
I think PayPal require SSL connection. When I google this issue. It seems not only nopcommerce but everyone have this issue. Since you are using sandbox environment I assume you can turn off SSL requirement in PayPal settings Just give it a go and see how it turns out
Auto Return for Website Payments: On Return Url: set with details of the first message PDT (optional): On Identity Token: set in the plungin config Encrypted Website Payments: Off PayPal Account optional: On Support Express checkout settings: off
Do you have SSL ? if so turn it on .. this seem to be an issue with security certificate can you check with the same configuration in a nopCommerce 3.9 installation? (latest version at the time of writing this )
