Application Programming Interface

Use the OpenStack APIs and extensions to launch server instances, create images, assign metadata to instances and images, create containers and objects, and complete other actions in your OpenStack cloud. OpenStack API Complete Reference

With the TryStack OpenStack installation, these services work together in the background of the installation. OpenStack API Guide
