## Delete a Message Batch

`client.Messages.Batches.Delete(ctx, messageBatchID) (*DeletedMessageBatch, error)`

**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://docs.claude.com/en/docs/build-with-claude/batch-processing)

### Returns

  - `ID string`

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