Reaction Messages

React to messages with emoji to acknowledge receipt or add context without sending a full reply.

React to a Message

The easiest way to react is using the reactions endpoint:

TypeScriptcURLCopy
const reaction = await zavu.messages.react("msg_abc123", {
  emoji: "👍"
});

React Using Message Type

You can also send a reaction as a message by specifying the WhatsApp message ID:

TypeScriptcURLCopy
const message = await zavu.messages.send({
  to: "+14155551234",
  channel: "whatsapp",
  messageType: "reaction",
  content: {
    emoji: "👍",
    reactToMessageId: "wamid.abc123..."
  }
});

Remove a Reaction

Send an empty string as the emoji to remove a reaction:

JSONCopy
{
  "to": "+14155551234",
  "channel": "whatsapp",
  "messageType": "reaction",
  "content": {
    "emoji": "",
    "reactToMessageId": "wamid.abc123..."
  }
}
