Is this statement true about using the IdentityNow APIs?

Yes, SailPoint IdentityNow's versioned APIs are fully supported. SailPoint uses versioning in their APIs to ensure backward compatibility, allowing clients to continue using older API versions while newer versions are introduced with additional features and improvements. Versioning helps maintain stability for applications that depend on the APIs.

Key Reference from SailPoint Documentation:

API Versioning: SailPoint IdentityNow provides support for versioned APIs, allowing developers to choose specific versions of the API, which are fully maintained and supported, to prevent breaking changes in integrations.
