3D-Guided Service Instructions 303: Create a Persistent Shopping Cart Using ThingWorx
Introduction
When you’re shopping on a website, you can add something to your shopping cart, and it will remain there until you’re ready to check out or until you manually remove the object; this concept is known as a persistent shopping cart. Up until now in this use case example, when you had added an item into your cart in your Vuforia Studio Experience, it disappeared if the Experience was restarted. To fix the issue, we’ll connect ThingWorx to Vuforia Studio so that the part information is stored in a persistent cart.
Import cartThing into ThingWorx Composer
Add cartThing to Vuforia Studio
Bind cartThing and Edit the 2D Canvas
Finalize the Vuforia Studio Experience
View the Experience
