Barclays ePDQ Extra Plus Omnipay

Barclays ePDQ Extra Plus Omnipay

Barclays ePDQ (Essential) is not the most intuitive gateway to use, so with that in mind, here are a couple of pointers for a slightly less painful integration experience:

The driver defaults to using POST for the post-transaction server-to-server callback. Make sure you also set the callback method to POST in the Barclays back office. Alternatively, you can use GET by configuring the driver using the setCallbackMethod() method.
Barclays only allow redirects to their payment page from URLs that you've already whitelisted. Make sure you've put the full URL of whichever page on your site does the redirect in the Barclays back office configuration.

The extension is provided by Github and is Free
