FAQ

Questions about Slash Command Used.

How does the Slash Command Used trigger work in Slack?

Fires when a user runs a configured slash command in Slack (e.g. /run-report). Use it as a manual trigger, letting Slack users kick off workflows on demand.

Is the Slash Command Used trigger real-time?

Yes. Slash Command Used uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Slack.

What data does Slash Command Used 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 Slash Command Used 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 Slash Command Used?

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.
