Have seen a few questions recently from independent developers and start-ups wanting to get access to a test environment so they can test code which uses the APIs to access Core PAS and the CyberArk Vault.
While the CyberArk Core PAS product APIs are public, currently, I’m not aware of any publicly accessible test environment for Core PAS. In general we encourage startups to contact the CyberArk Business Development team. Of course customers typically establish their own test environments to use prior to deployments.
