, and I see that there is a way to set variables in the userContext, but there is no documentation on how to read the value.
You can set the value with
rtp('set', 'customVar1', 'foo');
I assume that you can read the value with
var customVar1 = rtp('get', 'customVar1');
Is that correct?
I could test this out, but I have not enabled the User Context API yet.
