| # Matrix | ||
|
|
||
| ## URL Format | ||
|
|
||
| *matrix://__`user`__:__`password`__@__`host`__:__`port`__/[?rooms=__`!roomID1`__[,__`roomAlias2`__]][&disableTLS=yes]* | ||
|
|
||
| ## Authentication | ||
|
|
||
| If no `user` is specified, the `password` is treated as the authentication token. This means that no matter what login | ||
| flow your server uses, if you can manually retrieve a token, then Shoutrrr can use it. | ||
|
|
||
| ### Password Login Flow | ||
|
|
||
| If a `user` and `password` is supplied, the `m.login.password` login flow is attempted if the server supports it. | ||
|
|
||
| ## Rooms | ||
|
|
||
| If `rooms` are *not* specified, the service will send the message to all the rooms that the user has currently joined. | ||
|
|
||
| Otherwise, the service will only send the message to the specified rooms. If the user is *not* in any of those rooms, | ||
| but have been invited to it, it will automatically accept that invite. | ||
|
|
||
| **Note**: The service will **not** join any rooms unless they are explicitly specified in `rooms`. If you need the user | ||
| to join those rooms, you can send a notification with `rooms` explicitly set once. | ||
|
|
||
| ### Room Lookup | ||
|
|
||
| Rooms specified in `rooms` will be treated as room IDs if the start with a `!` and used directly to identify rooms. If | ||
| they have no such prefix (or use a *correctly escaped* `#`) they will instead be treated as aliases, and a directory | ||
| lookup will be used to resolve their corresponding IDs. | ||
|
|
||
| **Note**: Don't use unescaped `#` for the channel aliases as that will be treated as the `fragment` part of the URL. | ||
| Either omit them or URL encode them, I.E. `rooms=%23alias:server` or `rooms=alias:server` | ||
|
|
||
| ### TLS | ||
|
|
||
| If you do not have TLS enabled on the server you can disable it by providing `disableTLS=yes`. This will effectively | ||
| use `http` intead of `https` for the API calls. |
