PowerStore 4 Paypal Standard
I setup the Instant Payment Notification as per Webassist instuctions below.
"If you are using PayPal Standard as your payment gateway, you will be provided with an IPN page URL. This URL will need to be added to your PayPal Standard account details on the PayPal website.
Copy the IPN page URL that appears on the Gateway Settings tab of the Settings page in your Store Manager.
Log into the PayPal website at paypal.com.
Choose the Profile link from the sub main navigation.
Under Selling Preferences, choose the Instant Payment Notification Preferences option.
Select Choose IPN Settings.
In the Notification field, paste the IPN page URL that is provided in the Store Manager.
Select the "Receive IPN messages" checkbox.
but I get this message when I try to check out
Your transaction could not be completed. Either your credit card information or billing address has problems and cannot be processed
Please return to checkout and try again."
The people at Paypal are saying I need an API signature which I now have but do not know where to set these settings?
