Clear sensitive variables

This script demonstrates how to programmatically clear all sensitive variables in Projects and Variable Sets in an Octopus instance.

Usage

Provide values for the following:

  • Octopus URL
  • Octopus API Key

This script will clear all sensitive variable values from an Octopus instance. Take care when running this script or one based on it.
