Each user created in your OneLogin account has a role that determines the applications available to them. The Choreos in this bundle allow you to retrieve a list of roles or an individual role.
To use the Choreos in this bundle you need to have a OneLogin account. You can sign up for an account here. You also need an APIKey in order to authenticate with OneLogin. Once you've logged into your OneLogin account, you can find your APIKey by navigating to the Security tab, and then clicking the API tab.
