# CLIENT SETINFO

> Set client connection attributes.

Use `CLIENT SETINFO` to attach library identification to the current connection.

`LIB-NAME` records the name of the client library and `LIB-VER` its version. Both values then appear in [`CLIENT INFO`](/docs/redis/commands/connection/client-info) and [`CLIENT LIST`](/docs/redis/commands/connection/client-list) output, which makes it possible to tell which application or SDK version owns a connection. Most client libraries send this during the handshake, so applications rarely call it themselves.

## Syntax

```redis theme={"system"}
CLIENT SETINFO <LIB-NAME | LIB-VER> <value>
```

## Arguments

| Argument              | Required | Repeatable | Description                                              |
| --------------------- | -------- | ---------- | -------------------------------------------------------- |
| `LIB-NAME \| LIB-VER` | Yes      | No         | Attribute to update: the client library name or version. |
| `value`               | Yes      | No         | Value to store for the selected client attribute.        |

## Important points

* This is a connection-oriented command and is available over native Redis TCP, not the stateless REST endpoint.
* This command can expose administrative information or make a broad destructive change. Restrict it to trusted code paths.

## Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

| Protocol | Reply              |
| -------- | ------------------ |
| RESP2    | Simple string `OK` |
| RESP3    | Simple string `OK` |

<Note>
  Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
</Note>

## Examples

TCP examples use the TLS `REDIS_URL` from the Upstash console. REST examples use `UPSTASH_REDIS_REST_URL` and `UPSTASH_REDIS_REST_TOKEN`.
