Custom emojis
Unicode and custom server emojis.
You can use any Unicode emoji directly (paste into the emoji field). For custom server emojis, right-click the emoji in Discord and choose "Copy Markdown" — it gives you a string like <:emojiname:1234567890>. Paste the full string into the emoji field.
Bot must have access
Auditer can only react with custom emojis from servers it is a member of. If you use a custom emoji from a server Auditer is not in, the reaction will fail to add.
