Currently I am using Payflow gateway in one of my integrations. However, the Account verification which is also known as zero amount authorization which they have mentioned on their website(https://developer.paypal.com/docs/classic/payflow/integration-guide/) does not work for me. Following is the example that they have provided on their website:
TRXTYPE=A&TENDER=C&PARTNER=PayPal&USER=SuperUser&PWD=SuperUserPassword&AMT=0.00&ACCT=378282246310005 &EXPDATE=1215&INVNUM=PONUM1&VERBOSITY=HIGH&BILLTOZIP=95031
I tried it with this example and also edited a few other things such as I added vendor and CVV in the example but none of them seem to work. The error code that I get is 12 and the response message is declined. I know they have mentioned to contact issuing bank but I don't think the problem is related to bank because when I enter 0.01 amount the authorization passes without any error.
It will be really helpful if someone can provide a working example of account verification or zero amount authorization.
Kind Regards Het Parikh.
