| 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. |
