Retrieve a Message Batch

client.Messages.Batches.Get(ctx, messageBatchID) (*MessageBatch, error)

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.

ParametersExpand Collapse

messageBatchID string

ID of the Message Batch.

ReturnsExpand Collapse

type MessageBatch struct{…}

ID string

Unique object identifier.

The format and length of IDs may change over time.

ArchivedAt Time

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

formatdate-time

CancelInitiatedAt Time

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

formatdate-time

CreatedAt Time

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

formatdate-time

EndedAt Time

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.

formatdate-time

ExpiresAt Time

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

formatdate-time

ProcessingStatus MessageBatchProcessingStatus

Processing status of the Message Batch.

Accepts one of the following:

const MessageBatchProcessingStatusInProgress MessageBatchProcessingStatus = "in_progress"

const MessageBatchProcessingStatusCanceling MessageBatchProcessingStatus = "canceling"

const MessageBatchProcessingStatusEnded MessageBatchProcessingStatus = "ended"

RequestCounts MessageBatchRequestCounts

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.

Canceled int64

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

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

Errored int64

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

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

Expired int64

Number of requests in the Message Batch that have expired.

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

Processing int64

Number of requests in the Message Batch that are processing.

Succeeded int64

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

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

ResultsURL string

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.

Type MessageBatch

Object type.

For Message Batches, this is always "message_batch".

Accepts one of the following:

const MessageBatchMessageBatch MessageBatch = "message_batch"
