Hello, it seems this question gets asked fairly regularly here, but I failed to find any usable information in the forum or on the developer pages. Any transaction I try to process through a hosted pay page responds with an ERROR message and Response Code 959. I've tried using both MasterCard and Visa from here: https://developer.moneris.com/en/More/Testing/Testing%20a%20Solution
Typical response looks like this:
response_order_id=111&date_stamp=2020-02-07&time_stamp=16%3A43%3A26&bank_transaction_id=&charge_total=40.00&bank_approval_code=&response_code=959&iso_code=&message=ERROR&trans_name=purchase&cardholder=TestCard&f4l4=5454***5454&card=n%2Fa&expiry_date=2209&result=0&txn_num=&transactionKey=7k04mkXl5YNBAOYxaFXNdeJdzvmwdC
I'm trying to go through Store 2.
