The VuMark Generation API is part of Vuforia Web Services for generating printable instances of a VuMark. These instances are delivered as a graphics file that encodes the instance ID provided with the generation request. This ID may be in one of several data formats.
To generate VuMark instances, you'll need to create a VuMark database in the Target Manager and upload your VuMark template as an SVG file. You'll be able to obtain a set of keys for that database that you can use when calling the VWS API. See: How To Create a New VuMark Database
Note: Unlimited use of the VuMark Generation API is only available for Pro licensees.
