Since you don't get access to the DataStore, a Directory Utility (Project Utile) was written to allow PD Directory API calls.

URL is tied to the releaseName --> https://{releaseName}.ping-devops.com/utile/

Notes:

• Utile is a SPA protect by PingAccess -- PA is doing OIDC tokens and injecting (via a Groovy script) into the PD REST API call
• Credentials are in the Dashboard
