Important Notice Regarding PSD2 SCA And Popup Blocking
Adflex Hosted Payment Page v2
In anticipation of the forthcoming PSD2 directive regarding Strong Customer Authentication (SCA) due in September this year, we have been monitoring browser updates to see if there is any risk of service interruptions due to the new SCA 3DS issuer dialogues getting blocked as hostile (e.g. tripping the customer's Browser popup blocker)
To protect your calls to the Adflex service, we strongly recommend that you add an HTML5 “sandbox” attribute to your iframe that calls the Adflex payment page.
Failure to do so could result in transactions being lost due to the customers browser popup blocker.

Here is an example snippet of where to add the sandbox attribute
<div style="border:1px solid green; width:633px; height:724px;">
<iframe
src="https://testserver.adflex.co.uk/ahpp/transaction.aspx"
width="100%"
height="100%"
scrolling="no"
frameborder="0"
sandbox ="allow-forms allow-popups allow-scripts allow-top-navigation allow-same-origin" >
</iframe>
</div>
