How do I trigger when a Slack file is made public?

Short answer: In TinyCommand, add the Slack File Made Public trigger to a workflow and publish. It listens through a Slack webhook and fires your workflow within seconds of the event, with no polling and no code. Add a filter if you only want some events to start a run.

FAQ

Questions about File Made Public.

How does the File Made Public trigger work in Slack?

Fires when a file is made public via "Get a public link". Use it to audit external sharing or to kick off DLP/security flows.

Is the File Made Public trigger real-time?

Yes. File Made Public uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Slack.

What data does File Made Public return?

The full event payload from Slack. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.

Can I filter File Made Public so only some events start a workflow?

Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.

Do I need Slack admin permissions to use File Made Public?

For most Slack accounts a standard user can authorize the trigger. Some Slack plans require an admin to enable third-party webhooks. Check Slack's docs if the trigger fails to register.
