# DISCARD

> Discard queued commands.

Use `DISCARD` to throw away the commands queued since [`MULTI`](/redis/commands/transactions/multi) and leave the transaction without running anything.

It also clears every key watched with [`WATCH`](/redis/commands/transactions/watch), so the connection ends up in its normal state. This is what you call when the data you read after `WATCH` turns out to make the queued update unnecessary or invalid.

The raw command is TCP-only. Over HTTP, use the transaction or pipeline API of an Upstash SDK instead of sending this command directly.

## Syntax

```redis
DISCARD
```

## Arguments

This command takes no arguments.

## Important points

- The raw command is TCP-only. For HTTP, use an Upstash SDK transaction API rather than sending this command directly.

## 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`.
