## Streaming
### Chats
There is an additional `user:pleroma_chat` stream. Incoming chat messages will make the current chat be sent to this `user` stream. The `event` of an incoming chat message is `pleroma:chat_update`. The payload is the updated chat with the incoming chat message in the `last_message` field.
### Remote timelines
For viewing remote server timelines, there are `public:remote` and `public:remote:media` streams. Each of these accept a parameter like `?instance=lain.com`.
### Follow relationships updates
Pleroma streams follow relationships updatates as `pleroma:follow_relationships_update` events to the `user` stream.
The message playload consist of:
- `state`: a relationship state, one of `follow_pending`, `follow_accept` or `follow_reject`.
- `follower` and `following` maps with following fields:
- `id`: user ID
- `follower_count`: follower count
- `following_count`: following count
## User muting and thread muting
Both user muting and thread muting can be done for only a certain time by adding an `expires_in` parameter to the API calls and giving the expiration time in seconds.
