# ACL GETUSER

> Get the user's details.

Use `ACL GETUSER` to inspect the resulting permissions of a single ACL user, broken out into structured fields instead of the raw rule string that [`ACL LIST`](/docs/redis/commands/server/acl-list) returns.

The reply describes the user's on/off and other flags, its passwords, the commands it can call as a single space-separated permission string, the key patterns it can access, and the channel patterns it can publish to or subscribe on. A username that does not exist returns a null reply rather than an error, which makes this command a convenient way to check whether a user exists before creating or modifying it.

## Syntax

```redis theme={"system"}
ACL GETUSER <username>
```

## Arguments

| Argument   | Required | Repeatable | Description          |
| ---------- | -------- | ---------- | -------------------- |
| `username` | Yes      | No         | ACL user to inspect. |

## Important points

* Returns null when the given username does not exist, instead of an error.
* The reply has five fields: `flags`, `passwords`, `commands`, `keys`, and `channels`. Standard Redis 7+ also returns a `selectors` field; this deployment does not support selectors, so client libraries that expect one will simply receive an empty or undefined value for it.

## 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    | Flat array of alternating field names and values, with nested arrays for `flags`, `passwords`, `keys`, and `channels`; or Null array |
| RESP3    | Map of five fields, with a Set for `flags` and Arrays for `passwords`, `keys`, and `channels`; or Null                               |

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

## Examples

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