Global Payments / Realex's integration provides 2 options:
- HPP using Full Page Redirect - where the user is taken to a different page to enter their credit card details
- HPP using an iFrame - similar to above except the user thinks they are still on your website (as the user enters their credit card details on Realex's servers but it uses an invisible iFrame in the middle of the page to host the credit card screen)
Global Payments claim that both options are fully PCI Compliant as the user enters their credit card details on their servers.
To switch on either option only takes a minute so you can try out both options.
OPTION 1: HPP using Full Page Redirect
This option seems to be more stable than option 2 as option 2 uses iFrames are there seems to be issues with iFrames and the iOS operating system where on rare occasions, the customer is charged but their order does not complete.
OPTION 2: HPP using an iFrame
This is the nicer looking option but is not fully stable. On rare occasions, the customer can pay but their order does not complete successfully due to issues with iFrames and certain mobiles, so if using this option, you need to set up a validation check on each payment that is made so that if the order is not completed, you get an alert on your dashboard which should cover as a backup solution (which is not 100% secure either but is a large improvement).
To do this, send the following email to Global Payments technical support and substitute the parts in bold (firstname.lastname@example.org):
Please set up the 511 email alerts so that if any transaction does not complete successfully, an email is sent to me.
We are using HPP using an iFrame - so please set up a fallback response, where you trigger your system to always post the response independently of the iFrame to the following url:
Note that until you set up the above, the following alert will appear on your dashboard. And also, when it is set up, this alert only disappears when the first order goes through.
A second issue with Realex / Globaly Payments with OPTION 2 above
There is a second issue with Global Payments when Realex notify us that a customer has paid but the information on our system is different from their system. In 99% of these cases, the order is a valid order so we send you an email and let the order through telling you to double-check this order. The most common reason for this is often that a mobile phone user's browser refreshes the page with the credit card details twice without you knowing so we generate 2 order numbers for the transaction and Realex/Global Payments have one order number and we have the other order number - and in this case, all order details are the same on both systems except the order number is out by 1.
Option to SAVE CREDIT CARDS
