Reverse engineering quizizz reactions

In order to successfully send a reaction we will need 2 pieces of data roomHash hostID using this api https://game.quizizz.com/play-api

we can get these by posting {"roomCode": xxxx} to the endpoint /v5/checkRoom

Sending the reaction

using the endpoint /reactionUpdate we can send our payload The payload is as follows

 const payload = {
  "playerId": name, //Anything including swears
  "roomHash": this.roomHash, //REQUIRED
  "hostId": this.hostId,  //REQUIRED
  "questionId": "", //not required
  "triggerType": "live-reaction",
  "reactionDetail": {
    "id": type //1-7 changes the style of the reaction,
    "intensity": size, //[int] this will scale the reaction(big flaw)
  }
};
