 Placement API
===============

This is a reference for the OpenStack Placement API. To learn more about
OpenStack Placement API concepts, please refer to the
`Placement Introduction <https://docs.openstack.org/nova/latest/user/placement.html>`_.

The Placement API uses JSON for data exchange.  As such, the ``Content-Type``
header for APIs sending data payloads in the request body (i.e. ``PUT`` and
``POST``) must be set to ``application/json`` unless otherwise noted.
