How do I fetch metadata for a Slack file?

Short answer: You can get file in Slack by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Slack Get File action to a workflow, map its 1 input from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Get File.

What does the Get File action do in Slack?

Fetches metadata for a specific Slack file by ID (name, mimetype, size, download URL, shares). Used to verify a file or to prep a download.

What inputs does Get File require?

Required: File ID. 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 Slack returns an error?

The run history shows the failed step with its input and the error message Slack 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 Get File support batch operations?

Run Get File 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 Slack's rate limits.
