Question about custom Payment Plugin

[d***@blueyonder.co.uk]

Hi all,

I'm currently writing a new Payment Plugin for WCS 6.0 EE. All has gone well so far, commerce checkout talks to the plugin which talks to the 3rd party PSP and I get my response, process the payment etc and front end display the payment / order confrimation.

The problem is when the PSP throws a decline etc. I've used the tutorial / example code as a reference and when this happens, I throw a FinancialException, expecting the front end to reflect this, but the checkout progresses to finish, with the order status set to M

As a test I tried throwing both a PluginException and a FunctionNotSupportedException, both of these result in a front end generic error and looking at the trace are caught by a throw in the DoPaymentActionsPolicyCmdImpl

Anyhow, my (longwinded) question is, what's the best practise in dealing with responses / errors etc passed back from the PaymentPlugin, where should I put code to trap all this? Should I extend the DoPaymentActionsPolicyCmdImpl or put the code elsewhere etc?

Any input, as ever, greatly appreciated!

Hi all,

Just to clarify the last post after some more investigation, i'm now using the tutorial payment plugin MyWCPayments

1) If a FinancialException occurs, OrderProcess continues with error, even though in the WC_EDP trace you can clealy see the FinancialTransaction has a failure state. What's going on? How do I trap that this has occurred

2) Other exceptions such as a communication exception are caught and thrown, but I never get back a message from the plugin, I only ever get CMN3101E The system is unavailable due to "CMN0420E".

Is there any more info in using plugins - if not I shall revert to the 'usual' way of doing things, ie DoPaymentCmd etc

Thanks,

Dave

Did you try wrapping your exception as an ECSystemException, that will halt
the order flow?

yeah, should have updated the post, have added that in my super call and the errors are trapped fine now, however, still struggling with issue 1, I had a typo in the last post, what I meant was continues without error, ie...

1) If a FinancialException occurs, OrderProcess continues without error, even
though in the WC_EDP trace you can clealy see the FinancialTransaction has
a failure state. What's going on? How do I trap that this has occurred

..hence I can trap the communication errors etc, but if a financialexception is thrown the orderprocess carries on regardless...

Did you ever find a solution to this?
