Sorry to be a bother, but the customer tells me that they did enable PayPal Pro and have confirmation AND the submission still fails as you can see at the test URL https://bergogliolibri.it/peova.html
If you have any suggestion... thanks in advance!
Hi, in this case check the value of the variable "business" in the PRO form you are using, it must be one of the following two:
"Secure Merchant ID (found on the profile page) or the email address associated with your PayPal account."
If you pass the email address it must be in the standard email format firstname.lastname@example.org and not like the API user format myname_api1.mydomain.com
This will allow the PRO form working on https://bergogliolibri.it/peova.html
