How do I trigger when a specific word appears in Slack?

Short answer: Drop the "SlackKeyword Mentioned" trigger on your workflow canvas, add filters if you want them, and publish. It fires within seconds of the event in Slack, not on a polling schedule.

for the curious

You don’t need to read this. Tiny Command auto-maps every field into the visual picker so downstream nodes can pull values by clicking. We show it here for power users who want to know what’s on the wire.

FAQ

Questions about Keyword Mentioned.

How does the Keyword Mentioned trigger work in Slack?
Fires when a specific word or phrase appears in any Slack message. Use it for brand monitoring, escalation on words like "outage", or routing customer mentions.
Is the Keyword Mentioned trigger real-time?
Yes. Keyword Mentioned uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Slack.
What data does Keyword 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 Keyword 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.
Do I need Slack admin permissions to use Keyword Mentioned?
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.
