trigger slack message in servicenow

[ujjwala_678]

Hi All,

I have this new request to send slack message in servicenow using scheduled job 

Any existing script include I can utilise for this?

How should I fetch data using scheduled job? I am newbie to this integration 

Please feel free to share your thoughts on this. All kinds of suggestions are highly appreciated.

Thank you

Sure, I can guide you on how to send a Slack message from ServiceNow using a scheduled job. Here are the steps:

1. **Create a Slack App and Incoming Webhook:**
- Go to https://api.slack.com/apps and create a new app.
- From the app settings, select "Incoming Webhooks" and activate them.
- Add a new webhook to the workspace where you want to send messages. You will get a Webhook URL which will be used in ServiceNow.

2. **Create a Script Include in ServiceNow:**
- This script will be responsible for sending messages to Slack. Here is a sample script:

javascript
var SlackMessage = Class.create();
SlackMessage.prototype = {
initialize: function() {
},

send: function(webhook_url, message) {
var restMessage = new sn_ws.RESTMessageV2();
restMessage.setHttpMethod('post');
restMessage.setEndpoint(webhook_url);
restMessage.setRequestHeader('Content-Type', 'application/json');
var postBody = {
"text": message
};
restMessage.setRequestBody(JSON.stringify(postBody));
var response = restMessage.execute();
return response.getStatusCode();
},

type: 'SlackMessage'
};

3. **Create a Scheduled Job in ServiceNow:**
- This job will fetch data and send it to Slack. Here is a sample script:

javascript
var job = Class.create();
job.prototype = {
initialize: function() {
},

process: function() {
// Fetch data
var gr = new GlideRecord('table_name'); // replace 'table_name' with your table
gr.query();
while (gr.next()) {
// Prepare message
var message = 'Record: ' + gr.getValue('field_name'); // replace 'field_name' with your field

// Send message to Slack
var sm = new SlackMessage();
sm.send('your_webhook_url', message); // replace 'your_webhook_url' with your Slack Webhook URL
}
},

type: 'job'
};

4. **Schedule the Job:**
- Go to "System Definition > Scheduled Jobs" in ServiceNow.
- Create a new job and select the script you created in the previous step.
- Set the schedule according to your needs.

Please replace the placeholders in the scripts with your actual values. Also, make sure to test everything in a non-production instance first.
