FAQ

Questions about Add Reaction.

What does the Add Reaction action do in Discord?
Adds an emoji reaction to a Discord message from the bot. Used as a lightweight ack or to seed a reaction-vote message.
What inputs does Add Reaction require?
Required: Channel ID, Message ID, Emoji. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Discord returns an error?

Does Add Reaction support batch operations?
Yes. Run Add Reaction inside a Loop node to process arrays. Tiny Command handles Discord's rate limits automatically so you don't have to throttle manually.
