Order form split testing is done from the Content Menu Option > Order Forms Submenu Option

In the top right corner hit the + Icon to create a new Order Form Split test.[]

Name the Order Form Split test and you will get to the configuration screen.

Here you are provided a short code ( which can contain parameters to pass to the split tested paylink )

EG: $paylink form=2

Then you will be asked to provide the payment links that will be split tested.

Versions ( add at least one version to activate the form )

Note: It is possible to pass parameters to the short code that will get appended to the paylink, like cbitem=xcxx or vtid=somevtid EG: $paylink form=2 cbitem=xcxx vtid=somevtid
