How do I list all S3 buckets in my account?

Short answer: You can list buckets in AWS S3 by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the AWS S3 List Buckets action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about List Buckets.

What does the List Buckets action do in AWS S3?
Lists all S3 buckets in your AWS account, regardless of region. Used to populate a bucket picker or for audit/compliance reports.
What inputs does List Buckets require?
List Buckets has no required inputs. Sensible defaults are applied if you leave fields blank.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if AWS S3 returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does List Buckets support batch operations?
Yes. Run List Buckets inside a Loop node to process arrays. TinyCommand handles AWS S3's rate limits automatically so you don't have to throttle manually.

Other AWS S3 actions.

Action
Create Bucket
Creates a new S3 bucket in the chosen region. Bucket names are globally unique across all AWS accounts, so pick something account-prefixed; default ACL is private.
Action
Delete Object
Deletes a single object (file) from an S3 bucket by key. If versioning is enabled on the bucket, this just creates a delete marker; specify a VersionId to actually remove a version.
Action
Download Object
Downloads an object (file) from an S3 bucket by key. Large objects should usually be streamed via a presigned URL rather than buffered into a workflow step.
Action
List Objects
Lists objects in an S3 bucket, optionally scoped by prefix (folder). Returns up to 1000 keys per page; paginate with ContinuationToken for large buckets.
