Edge Device Security Claims Example
The example below illustrates how security claims can be added to an edge device and submitted to the ThingWorx Platform.
This example does the following:
Defines the target ThingWorx Platform to which the security claims are sent.
Defines an API Client for the edge device, setting both security claims and the target platform.
Illustrates how the security claims are processes by providing several sets of invalid claims, and one set of valid security claims.
