Send notifications to Google Chat from your workflow

You can create a workflow that sends messages to a Google Chat incoming webhook . Incoming webhooks let you send asynchronous messages into Google Chat from applications that aren't Chat apps. For example, you can configure a monitoring application to notify on-call personnel on Google Chat when a server goes down.

Create and register a Google Chat incoming webhook

In the Google Chat space where you want to receive messages, create a webhook. Follow the instructions to register the incoming webhook .

Make an HTTP call to the webhook URL

Create a workflow and add a step to the workflow that makes an HTTP POST call to the webhook URL. For example:

  
 - 
  
 get_message 
 : 
  
 call 
 : 
  
 http.post 
  
 args 
 : 
  
 url 
 : 
  
  WEBHOOK_URL 
 
  
 body 
 : 
  
 text 
 : 
  
 "Hello 
  
 world!" 
  
 headers 
 : 
  
 Content-Type 
 : 
  
 "application/json; 
  
 charset=UTF-8" 
  
 result 
 : 
  
 response 
  
 - 
  
 return_value 
 : 
  
 return 
 : 
  
 ${response} 

  
 [ 
  
 { 
  
 "get_message" 
 : 
  
 { 
  
 "call" 
 : 
  
 "http.post" 
 , 
  
 "args" 
 : 
  
 { 
  
 "url" 
 : 
  
 " WEBHOOK_URL 
" 
 , 
  
 "body" 
 : 
  
 { 
  
 "text" 
 : 
  
 "Hello world!" 
  
 }, 
  
 "headers" 
 : 
  
 { 
  
 "Content-Type" 
 : 
  
 "application/json; charset=UTF-8" 
  
 } 
  
 }, 
  
 "result" 
 : 
  
 "response" 
  
 } 
  
 }, 
  
 { 
  
 "return_value" 
 : 
  
 { 
  
 "return" 
 : 
  
 "${response}" 
  
 } 
  
 } 
  
 ] 

Replace WEBHOOK_URL with the webhook URL that you copied when registering the incoming webhook.

You can confirm that the workflow works as expected by ensuring that a notification is sent to your Google Chat space.
