FusionAuth Kickstart(tm) is super easy and if you can do it with an API, you can do it in Kickstart. Kickstart allows you to build a template that will be executed during startup to quickly replicate development or production environments.

It's a JSON document that is executed when a FusionAuth server is being started up from scratch, and allows you to replicate configuration between different environments. It's especially useful for CI environments, where you may want to run tests against a known configuration, and dev environments, where you may want to wipe and re-setup your FusionAuth instances regularly.
