Amazon S3 (2026-10-05)

Added new inputs and polling trigger capabilities, and fixed issues in file polling, bucket listing, and webhook message verification:

  • Added an optional Version ID input to the Get Object and Head Object actions for retrieving a specific object version
  • Added an optional Topic ARN input to the Webhook trigger that rejects messages from any other Amazon SNS topic
  • Added opt-in batching to the New and Updated Files trigger, dispatching each file individually or in configured batches so large backlogs drain in one recurrence; enabling it changes the shape a downstream step receives
  • Added opt-in batching to the New Buckets trigger, dispatching each bucket individually or in configured batches; enabling it changes the shape a downstream step receives
  • Added an optional Look-back Date input on the New and Updated Files and New Buckets triggers for performing an initial sync. The initial sync begins on the first recurrence and backfills every file modified, or bucket created, on or after the specified date, seeding each once; later recurrences are unaffected. Leave it empty to start from the first recurrence with no backfill
  • Updated List Objects to group its Max Keys and Continuation Token inputs into a Pagination structured object
  • Added inline action calling support across all actions for improved example output during configuration
  • Added output schemas to 29 actions for improved field mapping during configuration
  • Updated action labels: Bucket SNS Event Trigger Configuration is now Add Bucket SNS Event Notification, and the Upload Stream - Create Stream, Upload Stream - Write Data, and Upload Stream - Close Stream actions are now Create Upload Stream, Write Upload Stream, and Close Upload Stream
  • Fixed the New and Updated Files trigger missing files: files beyond the first 1,000 keys in a bucket were never detected, and a file modified in the same second a recurrence started was never returned
  • Fixed the List Buckets action, the Select Bucket data source, and the New Buckets trigger failing for AWS accounts with a general purpose bucket quota above 10,000, where Amazon S3 rejects unpaginated bucket listings
  • Fixed the Webhook trigger accepting messages not signed by Amazon SNS, including forged subscription confirmations it would then confirm against any URL
