Short answer: You can list buckets in AWS S3 by hand from its own interface, but it won’t repeat itself.

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 run history shows the failed step with its input and the error message AWS S3 returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does List Buckets support batch operations?

Run List Buckets inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within AWS S3's rate limits.
