Most variants also must pass server-side guest data to your organization's website, for example, the guest's first name, location, loyalty number, and so on. To facilitate this, you must configure the API response to include the dynamic data so that when the variant executes, the data is requested from the server and then passed to the variant.
The experience can call server-side data such as guest attributes, and use it in the CSJS. This can include a full history of the guest as well as a continuous stream of real-time session data.
On the Build screen, in the Experience section, click the Edit icon next to the variant you want to configure.
If there is a guest whose data you often use when configuring or testing code, click the star icon to bookmark the guest so you no longer have to search for them.
