Cancel a Message Batch

$client->beta->messages->batches->cancel(string messageBatchID, ?list<AnthropicBeta> betas, ?string workspaceID): MessageBatch
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.

The number of canceled requests is specified in request_counts. To determine which requests were canceled, check the individual results within the batch. Note that cancellation may not result in any canceled requests if they were non-interruptible.

string id

Unique object identifier.

The format and length of IDs may change over time.

?\Datetime archivedAt

RFC 3339 datetime string representing the time at which the Message Batch was archived and its results became unavailable.

?\Datetime cancelInitiatedAt

RFC 3339 datetime string representing the time at which cancellation was initiated for the Message Batch. Specified only if cancellation was initiated.

\Datetime createdAt

RFC 3339 datetime string representing the time at which the Message Batch was created.

?\Datetime endedAt

RFC 3339 datetime string representing the time at which processing for the Message Batch ended. Specified only once processing ends.

Processing ends when every request in a Message Batch has either succeeded, errored, canceled, or expired.

\Datetime expiresAt

ProcessingStatus processingStatus

Processing status of the Message Batch.

MessageBatchRequestCounts requestCounts

Tallies requests within the Message Batch, categorized by their status.

Requests start as processing and move to one of the other statuses only once processing of the entire batch ends. The sum of all values always matches the total number of requests in the batch.

?string resultsURL

URL to a .jsonl file containing the results of the Message Batch requests. Specified only once processing ends.

Results in the file are not guaranteed to be in the same order as requests. Use the custom_id field to match results to requests.
