Note that using a Developer license will limit you to 100 VuMark instance creations via the Vuforia Web Services APIs. With the same license type, there is no limit to the number of instances created via the Developer Portal. A Pro license provides unlimited instances to be generated using the APIs.
Hello,
The process for the creation of the VuMark template must include uploading it to the Vuforia Developer Portal via the Target Manager: https://library.vuforia.com/articles/Solution/How-To-Work-with-VuMark-Databases
Individual VuMark instances, uniquely encoded, can either be created on the Target Manager, or by using Vuforia Web Services APIs: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/Using-the-VuMark-Instance-Generation-API.html
