I am trying to implement the Westpac Payway gateway. I have tried with the default test account infomation that you provide when I choose Westpac Payway gateway on the https://admin.foxycart.com/admin.php?ThisAction=EditPaymentGateway
page in the 'Let customers pay with a Credit or Debit Card' section.
I did a test transcation and it failed with a "Error: There was an unknown gateway error."
I then went to the https://www.payway.com.au
site and set up a new test account. Unfortunately the information on your page: https://docs.foxycart.com/gateways/westpac
doesn't match the actual interface.
I did find where to add in the Foxycart IP addresses but got the same error when I did a test transaction
I wonder if things have changed too much on the Westpac side of things and there may need to be code changes to your integration with Westpac payway.
They do say that their API has changed, although they do claim you can use the old API for backward compatibility (and this is what I chose when setting up the test account)
I am testing on a local server using wampserver (if that makes any difference) but I had no problems testing the paypal payment processing with the same setup.
Could you please advise
