4.5 Hosted Pages in an iFrame

It is also possible to process transactions using an iFrame rather than a full redirect. All the same fields are required as the standard full redirect integration, but the implementation for the iFrame is slightly different.

There are two methods of doing this:

  1. Build and submit the form as with standard integration, but within the iFrame.
  2. Build the POST query string within the main page and then create an iFrame with the string as it's SRC value.


In either case you should also include this extra parameter:

Field Name Value Description
INIFRAME Y Ensures that all redirects our system performs do not break out of the iFrame.
