Hi prathiv23 If you have the implementation setup correctly these parameters get enabled automatically in the Target and analytics calls.
So please ensure that you are on the supported versions of the libraries as mentioned Before you implement
And ensure that the libraries are loaded in the right order . For the parameters to be set correctly you need load the libraries as follows.
Visitor ID service ---> Target --> Analytics .
If there is no supplemental data ID in the Target call, confirm that the VisitorAPI.js file is loaded before at.js or mbox.js. If there is no supplemental data ID in the Analytics call, confirm that the Target call fires before the Analytics call.
