If you have noticed a higher number of pending or failed transactions within WooCommerce, this is most likely caused by the customer closing the browser or moving to another website before the ePDQ system has had a chance to redirect them back to the website.
Luckily this can be fixed by enabling the Direct HTTP server-to-server request in the Transaction feedback section.
Some hosting providers may block this feature from working, The following hosts have no issues using this feature: 34SP, SiteGround and WPE (WP Engine), If you notice that this feature is not working for you, please work with your host to get this sorted.
The timing of the request must be set to: Always deferred or Online (either or will work fine).
Both input fields below that must be set like the following:
Simply replace https://www.demo.agdesignstudio.co.uk with your own domain.
Finally, make sure to set the request method to POST.
Now if the customer clicks away the ePDQ system will send the order data back to the website so it will log the correct order data.
How will you know if this has worked? If you enable the our plugins debug log, you will see an entry like this: API call back happened. This means the data sent back from Barclays was received by the plugin. The Direct HTTP server-to-server feature is working as it should.
