ServiceNow Slack Integration to Send Slack Messages

Hi All,
In this article we will look into how we can integrate ServiceNow to Slack. We have a usecase to send Salck Notification from ServiceNow whenever the record matches any given condition.

• Create a Rest Message for the Slack API , configuration for which are as given below 

• Create a Rest Resource for the same and provide the slack Authorisation details as highlighted on the screenshot
• 

Copy the preview script and Generate a Script include for the same

•  Script in the Script include as given below :
  

  var SlackNotificationUtils = Class.create();
  SlackNotificationUtils.prototype = {
  	initialize: function() {
  	},
  
  	sendSlackNotification : function (channelId,slackMessage) {
  		if (gs.nil(channelId)) {
  			throw 'Channel Id is empty';
  		}
  		var payload =
  			{
  				"channel": channelId,
  				"text": slackMessage
  			};
  
  		try { 
  			var r = new sn_ws.RESTMessageV2('Slack Notification for GDPR', 'Post Slack');
  			r.setRequestBody(JSON.stringify(payload));
  			var response = r.execute();
  			var responseBody = response.getBody();
  			var httpStatus = response.getStatusCode();
  			var obj = {
  				'responseBody' : responseBody,
  				'httpStatus' : httpStatus
  			};
  			
  			return JSON.stringify(obj);
  		}
  		catch(ex) {
  			var message = ex.message;
  			return JSON.stringify(message);
  		}
  	},
  	type: 'SlackNotificationUtils'
  };​

• Now we are done with the slack set up
• You can trigger the message to slack using below code for any table and any Slack Channel.
• Syntax for trigger is as given below :

 var channelId = <Target Slack Channel name>;

    var slackMessage = <Message you wanna share to Slack Channel>;

    var response = new SlackNotificationUtils().sendSlackNotification(channelId, slackMessage);

Hello @Amit Gujarathi ,

We also have alternate option like below:

If your instance has IntegrationHub and the Slack Spoke, you can automate Slack messages easily:

1. Enable Slack Spoke in your ServiceNow instance (requires IntegrationHub).
2. Create a Flow in Flow Designer.
3. Use the “Post Message” action from the Slack Spoke.
4. Configure the action:
• Choose the Slack connection
• Select the channel or user
• Write the message text
5. Add trigger conditions (e.g., incident created, updated, etc.).
6. Test the flow to confirm messages are being sent.

Hi @paragkanoje  

Tried through Integration Hub, it is so easy to configure and it works smooth like a butter 🙂
