React to a Facebook Messenger message
Adds or replaces the connected Pageβs emoji reaction on a Messenger message. Messenger accepts any emoji here, not a fixed list, so send the character itself (π) and not a name like βloveβ. Sending a different emoji on a message that already carries one replaces it: Messenger allows at most one reaction per sender per message. Note the reaction webhook reports only named types (smile, angry, sad, wow, love, like, dislike) and classifies everything else as βotherβ while still carrying the raw character, so an unusual emoji sends fine but reads back unnamed. Use DELETE on this path to remove a reaction.
