 Type: string
 Default value: ""

If you are using a WLS license and have retrieved your own token through the WLS REST API, use this parameter to pass that token to the library. If you do this, you don't need to set any other WLS-related parameters.

For examples of how to query or modify parameter values from our different APIs, refer to our Parameter Examples.
