Batches

Create a Message Batch
$client->beta->messages->batches->create(list<Request> requests, ?list<AnthropicBeta> betas, ?string userProfileID, ?string workspaceID): MessageBatch
POST/v1/messages/batches

Send a batch of Message creation requests.

Retrieve a Message Batch
$client->beta->messages->batches->retrieve(string messageBatchID, ?list<AnthropicBeta> betas, ?string workspaceID): MessageBatch
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
$client->beta->messages->batches->list(?string afterID, ?string beforeID, ?int limit, ?list<AnthropicBeta> betas, ?string workspaceID): Page<MessageBatch>
GET/v1/messages/batches

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

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.

Delete a Message Batch
$client->beta->messages->batches->delete(string messageBatchID, ?list<AnthropicBeta> betas, ?string workspaceID): DeletedMessageBatch
DELETE/v1/messages/batches/{message_batch_id}
Retrieve Message Batch results
$client->beta->messages->batches->results(string messageBatchID, ?list<AnthropicBeta> betas, ?string workspaceID): MessageBatchIndividualResponse
GET/v1/messages/batches/{message_batch_id}/results

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

Models
class DeletedMessageBatch { $type = 'message_batch_deleted'; $id; }
"message_batch_deleted" type

Deleted object type.

For Message Batches, this is always "message_batch_deleted".

string id

ID of the Message Batch.

class MessageBatch { $type = 'message_batch'; $id; $archivedAt; /* 7 more */ }
"message_batch" type

Object type.

For Message Batches, this is always "message_batch".

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

RFC 3339 datetime string representing the time at which the Message Batch will expire and end processing, which is 24 hours after creation.

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.

class MessageBatchCanceledResult { $type = 'canceled'; }
"canceled" type
class MessageBatchErroredResult { $type = 'errored'; $error; }
"errored" type
class MessageBatchExpiredResult { $type = 'expired'; }
"expired" type
class MessageBatchIndividualResponse { $customID; $result; }
string customID

Developer-provided ID created for each request in a Message Batch. Useful for matching results to requests, as results may be given out of request order.

Must be unique for each request within the Message Batch.

MessageBatchResult result

Processing result for this request.

Contains a Message output if processing was successful, an error response if processing failed, or the reason why processing was not attempted, such as cancellation or expiration.

class MessageBatchRequestCounts { $canceled; $errored; $expired; /* 2 more */ }
int canceled

Number of requests in the Message Batch that have been canceled.

This is zero until processing of the entire Message Batch has ended.

int errored

Number of requests in the Message Batch that encountered an error.

This is zero until processing of the entire Message Batch has ended.

int expired

Number of requests in the Message Batch that have expired.

This is zero until processing of the entire Message Batch has ended.

int processing

Number of requests in the Message Batch that are processing.

int succeeded

Number of requests in the Message Batch that have completed successfully.

This is zero until processing of the entire Message Batch has ended.

class MessageBatchResult
One of the following:
class MessageBatchSucceededResult { $type = 'succeeded'; $message; }
"succeeded" type
BetaMessage message
