1. Getting Started

Get ServiceNow now!

npm install service-now --save

Require, and Initiate

'use strict'
const ServiceNow = require('service-now');
var Snow  = new ServiceNow('https://<your-instance-name>.service-now.com/', yourUsername, yourPassword);

2. GET and POST - How to Query and Update Records (Class: Snow)

getRecords

A streamlined method to set your table and query then retrieving records.

Note: by default query Object contains "displayVariables: true". Each record's primary key will be converted to their proper value.

Snow.getRecords(queryObject,callback)

Code Example:

Snow.getRecords({
    table: 'sc_req_item',
    query: {
        number:'RITM0123456'
        }
    },(err,data) => {
    // Do Stuff Here.
});

setTable

Sets the table variable for your Snow instance.

Snow.setTable(Table)    // Table as String

Code Example:

Snow.setTable('sc_req_item');

setQuery

Sets the query variable for your Snow instance.

Snow.setQuery(Arguments[Object], DisplayVariables, DisplayValues)

Code Example:

Snow.setQuery({
    active: true,
    number: 'RITM0123456',
    }, 'true', 'false');

get

Gets records from using the variables set from the setTable and setQuery methods.

Snow.get(callback)

Code Example:

Snow.get((err,data) => {
    // Do Stuff Here.
});

post

Updates records using the variables set from the setTable and setQuery methods. This will update all records matching the query.

Snow.post(JSONbody[object], callback)

Code Example:

Snow.post({
    close_notes: 'Batch closing tickets from ServiceNow.',
    active: false
    }, (err, res) => {
    // Do stuff with updated records.
    }
);

3. RITM Methods (Class: Snow.Ritm)

getRitms

Gets RITMs matching the queryObject passed to the function.

Snow.Ritm.getRitms(queryObject, callback)

Code Example:

Snow.Ritm.getRitms({active: true, assignment_group: ''},(err,data) => {
    // Do Stuff Here.
});

getActive

Gets all active RITMs.

Snow.Ritm.getActive(callback)

Code Example:

Snow.Ritm.getActive((err,data) => {
    // Do Stuff Here.
});

getByNumber

Gets a single RITM by number.

Snow.Ritm.getByNumber(Number, callback)

Code Example:

Snow.Ritm.getByNumber('RITM0123456',(err,data) => {
    // Do Stuff Here.
});

closeByNumber

Closes a single RITM by number.

Snow.Ritm.closeByNumber(Number, CloseNotes, callback)

Code Example:

Snow.Ritm.closeByNumber('RITM0123456', 'Closing the ticket, issue was resolved.',(err,data) => {
    // Do Stuff Here.
});

4. User Methods (Class: Snow.User)

getUsers

Gets all users in your SNOW instance.

Snow.User.getUsers(callback)

Code Example:

Snow.User.getUsers((err,data) => {
    // Do Stuff Here.
});

getUserGroups

Gets all user groups in your SNOW instance.

Snow.User.getUserGroups(callback)

Code Example:

Snow.User.getUserGroups((err,data) => {
    // Do Stuff Here.
});

getUserByUserName

Gets a single user by their username in your SNOW instance.

Snow.User.getUserByUserName(username, callback)

Code Example:

Snow.User.getUserByUserName('JSmith', (err,data) => {
    // Do Stuff Here.
});

getUserById

Gets a single user by their sys_id in your SNOW instance.

Snow.User.getUserById(userId, callback)

Code Example:

Snow.User.getUserByUserName('007c75ce6f2c9100222a57ee2c3ee43d', (err,data) => {
    // Do Stuff Here.
});

5. Category Methods (Class: Snow.Category)

    // Do Stuff Here.
});

6. Utility Methods (Class: Snow.Utilities)

groupBy

Groups an array of JSON documents by a specific oject property.

Snow.Utilities.groupBy(data, property, callback)

Code Example:

Snow.Ritm.getActive((err, data) => {
    Snow.Utilities.groupBy(data, 'cat_item', groupData => {
        // Do Stuff Here
    });
});

flattenVariables

Note: Only for use with RITM documents when querying the same cat_item. Refactors the embedded variables document, to be included in the parent document.

Snow.Utilities.flattenVariables(data, callback)

Code Example:

Snow.Ritm.getActive((err, data) => {
    Snow.Utilities.flattenVariables(data, flatData => {
        // Do Stuff Here
    });
});

Script Examples

Query Records Script Example 1

This is the preferred method of querying records.

'use strict'
const ServiceNow = require('service-now');
var Snow  = new ServiceNow('https://<your-instance-name>.service-now.com/', yourUsername, yourPassword);

Snow.getRecords({
    table: 'sc_req_item',
    query: {
        number:'RITM0123456'
        }
    },(err,data) => {
    // Do Stuff Here.
});

Query Records Script Example 2

This is an alternative method of querying records.

'use strict'
const ServiceNow = require('service-now');
var Snow  = new ServiceNow('https://<your-instance-name>.service-now.com/', yourUsername, yourPassword);

// Input whatever table you like.
Snow.setTable('sc_req_item');

// Declare your query object, and the 'displayvariables' & 'displayvalues' boolean as a string. By default it is true.
// Snow.setQuery(QueryObject, DisplayVariables, DisplayValues);
Snow.setQuery({
    active: true,
    number: 'RITM0123456',
    }, 'true', 'false');

// Get your data and do stuff.
Snow.get((err,data) => {
    // Do Stuff Here.
});

Update Records Script Example 2

This is an example method of updating records.

'use strict'
const ServiceNow = require('service-now');
var Snow  = new ServiceNow('https://<your-instance-name>.service-now.com/', yourUsername, yourPassword);

// Set your table.
Snow.setTable('sc_req_item');

// Set your query.
Snow.setQuery({
    active:true,
    priority: 3
    }, 'true', 'true');

// In this example we close all the tickets matching our query.
Snow.post({
    close_notes: 'Batch closing tickets from ServiceNow.',
    active: false
    }, (err, res) => {
    // Do stuff with updated records.
    }
);
