## Delete a Message Batch

**delete** `/v1/messages/batches/{message_batch_id}`

Delete a Message Batch.

Message Batches can only be deleted once they've finished processing. If you'd like to delete an in-progress batch, you must first cancel it.

Learn more about the Message Batches API in our [user guide](https://platform.claude.com/docs/en/build-with-claude/batch-processing)

### Path Parameters

- `message_batch_id: string`

  ID of the Message Batch.

### Returns

- `DeletedMessageBatch object { id, type }`

  - `id: string`

    ID of the Message Batch.

  - `type: "message_batch_deleted"`

    Deleted object type.

    For Message Batches, this is always `"message_batch_deleted"`.

    - `"message_batch_deleted"`

### Example

```http
curl https://api.anthropic.com/v1/messages/batches/$MESSAGE_BATCH_ID \
    -X DELETE \

```
