Delete a Message Batch

messages.batches.delete(message_batch_id, **kwargs) -> DeletedMessageBatch
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.
