Create Signed URL

Configuration
3 fields, 2 required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.

path Object key to sign, including any folder prefix. | string | Yes | — | — | 2026/09/invoice-1001.pdf |
expires_in How many seconds the URL stays valid after it is issued. | number | No | 3600 | ≥ 1 | — |

Every value below is the contract’s own example or default — nothing invented.

In a technical demo we add the Supabase connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
