Link to this function

add_reaction(message, emoji)

Specs

add_reaction(
  Alchemy.Message.t() | {channel_id(), message_id()},
  unicode() | Alchemy.Reaction.Emoji.t()
) :: {:ok, nil} | {:error, term()}

Adds a reaction to a message.

This supports sending either a custom emoji object, or a unicode literal. While sending raw unicode is technically possible, you'll usually run into url encoding issues due to hidden characters if you try to send something like "❤️️"; use \u2764 instead.

Examples

Cogs.def heart do
  Client.add_reaction(message, "️\u2764")
end
