How do I trigger when my Slack app is @-mentioned?

Short answer: In TinyCommand, add the Slack App Mentioned 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 App Mentioned.

How does the App Mentioned trigger work in Slack?

Fires when your Slack app is mentioned in a message. The standard hook for chatbots that answer when summoned with @your-app.

Is the App Mentioned trigger real-time?

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

What data does App Mentioned 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 App Mentioned 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.

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.
