Barclaycard ePDQ for 1.3.7

[abrown21]

I have installed the installation files and setup the Payment module in ZenCart. However, I am having no luck setting up the EPDQ CPI parameters as I keep getting "INVALID URL ALLOWED" from the Barclays website.

I think the problem may be the Allowed URL and/or the POST URL. What should these be?

I noticed a very old post that stated HTTPS on the POST URL was not allowed, is this still the case?

Any advice greatly appreciated.

It's most likely the allowed URL as the POST URL that you set in your CPI admin is over-ridden (for good reason) by the mod.

I don't know whether https addresses are not supported and would recommend talking to ePDQ support directly on this point. They're open until midnight.

Oops. Previous response was sloppy. Confused POST and return URLs. But the main part remains the same - a problem with the allowed URL.

After further testing it seems that the POST URL is a bit limiting. Basically Barclays require an absolute URL and does not allow session ids.

Originally the post URL was in the following format:

http://www.domain.com/checkout_confi...enid=123456789

This needed to be changed to:

http://www.domain.com/checkout_confirmation.htm


We have had to amend the previous page (Checkout Payment) so that the post URL from this page excluded the zenid parameter. This meant when the page redirected to barclays the referrer was correct.

How did you get around the issue if the customer completes the transaction, but doesn't press continue on the final ePDQ page, leaving you with cash, but no return to Zen Cart to complete the order?

How are you recognizing and handling a declined transaction in Zen Cart?

Basically Barclays require an absolute URL and does not allow session ids.

It's possible that you're mixing up the POST and return URLs here. Though your comment would apply to both but at a more fundamental level.

It seems to me that Baraclays are stripping away all URL parameters (which does have some security benefits) and replacing them with the order ID for the return URL and the transaction status data for the POST URL. Dynamic URL parameters such as used by Zen Cart by default and session IDs are just two examples of what gets stripped.

I haven't go this far yet... we are waiting on Barclays to put the account live as the sand box area does not support a full transaction test apparently!

I'll keep you informed... no doubt back for more advice!

They told me they didn't have a Sandbox only a live environment, but that we could have a test account against that. Haven't been able to make that happen though, and we've ended up testing in the live environment against a live site

Stand by for a PM.

Every Time i Install this mod it removes all my payment Module

With Out

Even without the problem, you seem to be missing some payment modules, i.e. authorize.net.

I doubt that the modules are being removed, but rather that there's a php error occuring. I've just downloaded the mod from the downloads area to check that it hadn't been corrupted. It installed with no problem, so this looks like something local to your system.

I would recommend installing the Zen Cart Debug Logger to find out what the error is and where its occurring.
