AA passing Visitor ID (mid) from querystring parameter to an eVar

[urvijag76854707]

Hi

I have a single page application using react js. AA implementation is done using launch. The requirement is to track user behaviour on the site and combine it with offline data. Now i want to populate the Visitor ID into an eVar so that i can link it with the customer ID (hashed email value captured in a different eVar). Can some one please explain how we can pass the visitor ID(its available in querystring parameter as mid) into an evar.

The Experience Cloud ID is found in the data collection query string, and uses the parameter "mid". A list of the data collection query parameters can be found at https://docs.adobe.com/content/help/en/analytics/implementation/javascript-implementation/data-colle... .

You can use the dynamic variable approach in Adobe Launch, which is outlined at https://docs.adobe.com/content/help/en/analytics/implementation/javascript-implementation/variables-... . You'll need to mess around with the Data Elements to get this to work, which you can also read about at https://jimalytics.com/tag-management/adobe-launch-data-elements-guide/ .
