# 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`](/docs/redis/commands/streams/xack) and [`XDEL`](/docs/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 theme={"system"}
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.
</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`.
