Purge history API examples
|
||||
==========================
|
||||
|
||||
# `purge_history.sh`
|
||||
|
||||
A bash file, that uses the [purge history API](/docs/admin_api/README.rst) to
|
||||
purge all messages in a list of rooms up to a certain event. You can select a
|
||||
timeframe or a number of messages that you want to keep in the room.
|
||||
|
||||
Just configure the variables DOMAIN, ADMIN, ROOMS_ARRAY and TIME at the top of
|
||||
the script.
|
||||
|
||||
# `purge_remote_media.sh`
|
||||
|
||||
A bash file, that uses the [purge history API](/docs/admin_api/README.rst) to
|
||||
purge all old cached remote media.
