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

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:

 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.
