S3 Storage node
Uploads, downloads, lists and deletes files in Amazon S3 buckets — the file layer for flows that produce or consume documents and media.
S3 Storage (s3_storage) connects flows to S3: persist generated files (PDFs, exports), fetch inputs, list bucket contents or clean up.

- Node ID / Name — the identifier used in variables and the display name on the canvas.
- Credentials & bucket — where to operate.
- Operation — upload / download / list / delete, with key patterns.
Inputs & outputs
It receives file data or keys and emits results (URLs, contents, listings). Downstream nodes reference its output with {{node_id.field}} — see the variables reference.
