# XACKDEL

> Acknowledge and delete messages.

Use `XACKDEL` to acknowledge entries in a consumer group and delete them from the stream in one atomic step.

It combines what [`XACK`](/redis/commands/streams/xack) and [`XDEL`](/redis/commands/streams/xdel) do, which is what you want when a stream serves a single group and processed entries have no reason to stay around. `IDS <numids>` introduces the list of IDs and the count must match.

The reference policy controls what happens to consumer group references of the deleted entries: `KEEPREF`, the default, leaves references in other groups' pending lists in place, `DELREF` removes them everywhere, and `ACKED` only deletes entries that every group has read and acknowledged, leaving the rest in the stream. The reply holds one status code per requested ID, in order.

## Syntax

```redis
XACKDEL <key> <group>
  [KEEPREF | DELREF | ACKED]
  IDS <numids> <id> [<id> ...]
```

## Arguments

| Argument | Required | Repeatable | Description |
| --- | --- | --- | --- |
| `<key>` | Yes | No | Redis key targeted by the command. |
| `<group>` | Yes | No | Consumer group name. |
| `(KEEPREF \| DELREF \| ACKED)` | No | No | What happens to consumer-group references of the deleted entries: `KEEPREF` (the default) leaves them in place, `DELREF` removes them from every group's pending list, and `ACKED` only removes entries that every group has read and acknowledged. |
| `IDS <numids> <id> [<id> ...]` | Yes | No | Entry IDs to target. Give the ID count first, then that many IDs. |

## 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 | Array of integer status codes, one per ID |
| RESP3 | Array of integer status codes, one per ID |

<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`.
