Purge History API
=================

The purge history API allows server admins to purge historic events from their
database, reclaiming disk space.

**NB!** This will not delete local events (locally sent messages content etc) from the database, but will remove lots of the metadata about them and does dramatically reduce the on disk space usage

Depending on the amount of history being purged a call to the API may take
several minutes or longer. During this period users will not be able to
paginate further back in the room from the point being purged from.

The API is simply:

``POST /_matrix/client/r0/admin/purge_history/<room_id>/<event_id>``

including an ``access_token`` of a server admin.

make it absolutely clear that Purge History API does not remove all traces of events and message contents because this topic pops up too often #890 #1621 #1730 #2260 #2315 and so on 2017-10-14 12:25:42 +02:00			`NB!
