Setting it up
1
Copy the message link
Right-click the message you want to use in Discord and select Copy Message Link. If the message is in the same channel you will be running the command in, the message ID alone is enough (enable Developer Mode in Discord’s settings if you do not see this option).
2
Run the command
Run
/reactionrole add <message> <emoji> <role> with the link you copied, the emoji members will click, and the role they should receive. If the message is in a different channel from where you are typing, include the [channel] option.3
Check the message
Newt adds the emoji to the message straight away, so members have something to click. They react to gain the role and remove their reaction to lose it.
Things worth knowing
Commands only. Reaction roles have no dashboard equivalent. If you would prefer to manage role assignments from the dashboard, use Role Buttons instead. Removing a reaction role. Running/reactionrole remove removes the link between the emoji and the role. Members who already hold the role keep it — they are not stripped of it when you remove the configuration.
Custom emoji. Custom emoji must come from a server that Newt is in, or it cannot react with them. If a custom emoji is later deleted from its original server, that reaction role stops working.
Silent operation. Reaction roles are silent — no confirmation message appears when someone gains or loses a role. A reaction cannot reply privately the way a button can, so members have no immediate feedback if something goes wrong.
If nothing happens. The most common reason a reaction does nothing is that Newt’s role sits below the role it is trying to assign in the role hierarchy. Go to Server Settings → Roles and drag Newt’s role above the affected role.
Deleted messages. If you delete the message that reaction roles are attached to, all of those reaction roles are removed along with it.
If you want members to receive a private confirmation when they click — or if you need them to know why a click did nothing — use Role Buttons instead. Buttons reply privately and can explain exactly what happened.
