FAQ

Questions about Download Object.

What does the Download Object action do in AWS S3?

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.

What inputs does Download Object require?

Required: Bucket Name, Object Key. Every input accepts a static value or a variable from any upstream node in your workflow.

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 Download Object support batch operations?

Run Download Object 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.
