+## how to set retention period on matrix rooms
+
+SEE: https://github.com/matrix-org/matrix-spec-proposals/blob/matthew/msc1763/proposals/1763-configurable-retention-periods.md
+
+TBH i'm struggling a bit to set the retention in an automated fashion at all. We don't have a tool for it and it requires having admin in the room.
+The best I was able to figure out so far
+
+ 1. go to the cyberia space with the network tab of the dev tools open
+
+ 2. look for the _matrix/client/v1/rooms/!XJhdXteYnRMldzWFyX%3Acyberia.club/hierarchy?suggested_only=true&max_depth=1&limit=20 GET request and copy its json response
+
+ 3. extract the room ids with `jq`
+ 4. ssh into the matrix server and run `./reset-password ed-209:cyberia.club`
+ 5. log in as ed-209
+ 6. go to a room then type `/devtools` to open the devtools, and make sure the browser network tab is open
+ 7. send a custom room state event with event type m.room.retention and body `{"max_lifetime":86400000000}`
+ 8. find the `PUT _matrix/client/r0/rooms/!roqAKCndauLBfhLdGs%3Acyberia.club/state/m.room.retention/` request in the network tab and right click -> copy as curl
+ 9. write a script that runs this curl command for every room ID that you collected
+
+```
+(()=>{
+
+ const list = `!JFYMcOkcWtccikJlkA%3Acyberia.club
+!SfvWHaBPcmgzTWdvZB%3Acyberia.club
+!hYrELkZnhpqlzZoQZZ%3Acyberia.club
+blahbalahblahbah....`.split("\n");
+
+const space = `
+
+
+`;
+ console.log(space +
+ list.map(roomid => {
+ return `curl 'https://matrix.cyberia.club/_matrix/client/r0/rooms/${roomid}/state/m.room.retention/' -X PUT AUTH HEADER GOES HERE!!! --data-raw '{"max_lifetime":86400000000}'`
+ }).join('\n\n\n')+space);
+
+})()
+
+```
+
+so far its been slightly hit and miss but I'll check a few rooms and make sure it at least appears to have worked
+
+( you can check a room by typing `/devtools` in the message box and then going to the explore room state section, there should be an entry for m.room.retention )
