In some cases, you want to capture http header information into a custom field. Here’s an example to save the referring URL.

If embedded this will be the URL of the landing page where the Decision Tree is embedded.

Say you have 3 URL’s with one Decision Tree. In this case you would have the need to determine which URL was accessed.

This can be accomplished with some JavaScript

  1. First create a text custom field. We can call this ‘referrer’

2. Next add this code to the first node of the Decision Tree. It should fire on enter of the 1st node.

var x = document.referrer;
DT.setField('referrer', x);

3. Now you can print the custom field like so: {referrer}
