Batches

Create a Message Batch

beta.messages.batches.create(**kwargs) -> BetaMessageBatch

POST/v1/messages/batches

Send a batch of Message creation requests.

Retrieve a Message Batch

beta.messages.batches.retrieve(message_batch_id, **kwargs) -> BetaMessageBatch

GET/v1/messages/batches/{message_batch_id}

This endpoint is idempotent and can be used to poll for Message Batch completion. To access the results of a Message Batch, make a request to the results_url field in the response.

List Message Batches

beta.messages.batches.list(**kwargs) -> Page<BetaMessageBatch>

GET/v1/messages/batches

List all Message Batches within a Workspace. Most recently created batches are returned first.

Cancel a Message Batch

beta.messages.batches.cancel(message_batch_id, **kwargs) -> BetaMessageBatch

POST/v1/messages/batches/{message_batch_id}/cancel

Batches may be canceled any time before processing ends. Once cancellation is initiated, the batch enters a canceling state, at which time the system may complete any in-progress, non-interruptible requests before finalizing cancellation.

Delete a Message Batch

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

DELETE/v1/messages/batches/{message_batch_id}

Retrieve Message Batch results

beta.messages.batches.results_streaming(message_batch_id, **kwargs) -> JsonLStream<BetaMessageBatchIndividualResponse>

GET/v1/messages/batches/{message_batch_id}/results

Streams the results of a Message Batch as a .jsonl file.
