Delete a reaction from a message

This guide explains how to use the delete() method on the Reaction resource of the Google Chat API to delete a reaction from a message—like 👍, 🚲, and 🌞. Deleting a reaction doesn't delete the message.

The Reaction resource represents an emoji that people can use to react to a message, such as 👍, 🚲, and 🌞.

Prerequisites

Node.js

Delete a reaction

To delete a reaction from a message, pass the following in your request:

  • Specify the chat.messages.reactions or the chat.messages authorization scope.
  • Call the DeleteReaction() method, passing the name as the resource name of the reaction to delete.

The following example deletes the 😀 reaction from a message:

Node.js

chat/client-libraries/cloud/delete-reaction-user-cred.js
import {createClientWithUserCredentials} from './authentication-utils.js';

const USER_AUTH_OAUTH_SCOPES = ['https://www.googleapis.com/auth/chat.messages.reactions'];

// This sample shows how to delete a reaction to a message with user credential
async function main() {
  // Create a client
  const chatClient = await createClientWithUserCredentials(USER_AUTH_OAUTH_SCOPES);

  // Initialize request argument(s)
  const request = {
    // Replace SPACE_NAME, MESSAGE_NAME, and REACTION_NAME here
    name: 'spaces/SPACE_NAME/messages/MESSAGE_NAME/reactions/REACTION_NAME'
  };

  // Make the request
  const response = await chatClient.deleteReaction(request);

  // Handle the response
  console.log(response);
}

main().catch(console.error);

To run this sample, replace the following:

  • SPACE_NAME: the ID from the space's name. You can obtain the ID by calling the ListSpaces() method or from the space's URL.
  • MESSAGE_NAME: the ID from the message's name. You can obtain the ID from the response body returned after creating a message asynchronously with the Chat API, or with the custom name assigned to the message at creation.
  • REACTION_NAME: the ID from the reaction's name. You can obtain the ID by calling the ListReactions() method, or from the response body returned after creating a reaction asynchronously with the Chat API.

If successful, the response body is empty, which indicates that the reaction is deleted.
