# Subscribing to events via Websocket
Tendermint emits different events, to which you can subscribe via
[Websocket](https://en.wikipedia.org/wiki/WebSocket). This can be useful
for third-party applications (for analysys) or inspecting state.
[List of events](https://godoc.org/github.com/tendermint/tendermint/types#pkg-constants)
You can subscribe to any of the events above by calling `subscribe` RPC
method via Websocket.
{
"jsonrpc": "2.0",
"method": "subscribe",
"id": "0",
"params": {
"query": "tm.event='NewBlock'"
}
}
Check out [API docs](https://tendermint.github.io/slate/#subscribe) for
more information on query syntax and other options.
You can also use tags, given you had included them into DeliverTx
response, to query transaction results. See [Indexing
transactions](./indexing-transactions.md) for details.
