How do I trigger when a reaction is added to a Discord message?

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

What this trigger returns

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.

{
  "user": "123456",
  "emoji": "👍",
  "channel": "234567",
  "message": "345678"
}

FAQ

Questions about Reaction Added.

How does the Reaction Added trigger work in Discord?

Fires when a reaction is added to a Discord message. Powers reaction-roles, voting, or "thumbs up to claim" automations.

Is the Reaction Added trigger real-time?

Yes. Reaction Added uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Discord.

What data does Reaction Added return?

The full event payload from Discord. 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 Reaction Added 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 Discord admin permissions to use Reaction Added?

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