React to a Message with an Emoji
View All WhatsApp Messaging API APIs →Add an emoji reaction to a message. Send a JSON body with the chatJid and the messageId of the target message, plus the emoji to apply. Send an empty-string emoji to remove your reaction. For group messages you may pass senderJid to identify the original sender; it is inferred from the in-memory cache when omitted. Returns the upstream result.
