Add a reaction

POST /v1/chats/messages/:messageId/reactions

Adds the current user's reaction to a message. The chat is resolved from the message, so no dialogId is needed.

A reaction is set by a camelCase code: like, fire, laugh, faceWithThermometer. The set of codes is defined by Bitrix24 and may grow. In version im 26.1300 there are 48: like, faceWithTearsOfJoy, redHeart, neutralFace, fire, cry, slightlySmilingFace, winkingFace, laugh, kiss, wonder, slightlyFrowningFace, loudlyCryingFace, faceWithStuckOutTongue, faceWithStuckOutTongueAndWinkingEye, smilingFaceWithSunglasses, confusedFace, flushedFace, thinkingFace, angry, smilingFaceWithHorns, faceWithThermometer, facepalm, poo, flexedBiceps, clappingHands, raisedHand, dislike, smilingFaceWithHeartEyes, smilingFaceWithHearts, pleadingFace, relievedFace, foldedHands, okHand, signHorns, loveYouGesture, clownFace, partyingFace, questionMark, exclamationMark, lightBulb, bomb, sleepingSymbol, crossMark, whiteHeavyCheckMark, eyes, handshake, hundredPoints.

messageId (path) number yes Message ID, a positive integer — from the chat feed (GET /v1/chats/:dialogId/messages) or from the send response

Request fields (body)

Any other body field and any query parameter are rejected with 400 INVALID_PARAMS.

Known specifics

One reaction per code. Different codes on the same message are added independently. Repeating the same code returns the REACTION_ALREADY_SET error.
