AWS S3 actions

preview

We're still working on this feature, but we'd love for you to try it out!

This feature is currently provided as part of a preview program pursuant to our pre-release policies.

This page provides a comprehensive reference for aws s3 actions available in the workflow automation actions catalog. These actions enable you to s3 bucket and object operations.

Prerequisites

Before using AWS actions in workflow automation, ensure you have:

An AWS account with appropriate permissions.
AWS credentials configured (IAM user credentials, IAM role ARN, or session credentials).
The necessary IAM permissions for the specific AWS services you plan to use.

See Set up AWS credentials for information on how to create IAM users and IAM roles, and set up static and session AWS credentials for integration with workflow automation AWS actions.

The listObjectsV2 method returns some or all (up to 1,000) of the objects in a bucket. It is a more modern and recommended version of list_objects.

The deleteObject method permanently removes a single object from a bucket. For versioned buckets, this operation inserts a delete marker, which hides the object without permanently deleting it unless a VersionId is specified.
