The Okta Java SDK API .jar provides a Java API that your code can use to make calls to the Okta API. This .jar is the only compile-time dependency within the Okta SDK project that your code should depend on. Implementations of this API (implementation .jars) should be runtime dependencies only.

There is a newer version: 21.0.0
