Extend Google Sheets with ServiceNow Data



Make calls to the API Server from Google Apps Script.

Interact with ServiceNow data from Google Sheets through macros, custom functions, and add-ons. The CData API Server, when paired with the ADO.NET Provider for ServiceNow (or any of 200+ other ADO.NET Providers), enables connectivity to ServiceNow data from cloud-based and mobile applications like Google Sheets. The API Server is a lightweight Web application that produces OData services for ServiceNow and any source supported by the CData ADO.NET Providers.

Google Apps Script can consume these OData services in the JSON format. This article shows how to create a simple add-on that populates a Google Spreadsheet with incident data.

About ServiceNow Data Integration

CData simplifies access and integration of live ServiceNow data. Our customers leverage CData connectivity to:

  • Get optimized performance since CData uses the REST API for data and the SOAP API for schema.
  • Read, write, update, and delete ServiceNow objects like Schedules, Timelines, Questions, Syslogs and more.
  • Use SQL stored procedures for actions like adding items to a cart, submitting orders, and downloading attachments.
  • Securely authenticate with ServiceNow, including basic (username and password), OKTA, ADFS, OneLogin, and PingFederate authentication schemes.

Many users access live ServiceNow data from preferred analytics tools like Tableau, Power BI, and Excel, and use CData solutions to integrate ServiceNow data with their database or data warehouse.


Getting Started


Set Up the API Server

Follow the steps below to begin producing secure ServiceNow OData services:

Deploy

The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.

The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.

Connect to ServiceNow

After you deploy the API Server and the ADO.NET Provider for ServiceNow, provide authentication values and other connection properties needed to connect to ServiceNow by clicking Settings -> Connections and adding a new connection in the API Server administration console.

ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, specify the Instance, Username, and Password connection properties.

See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

You can then choose the ServiceNow entities you want to allow the API Server to access by clicking Settings -> Resources.

Authorize API Server Users

After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address: Connections from all addresses except localhost are blocked by default, so you will need to allow connections from Google's servers for this article. You can authenticate as well as encrypt connections with SSL.

Retrieve ServiceNow Data

Open the Script Editor from your spreadsheet by clicking Tools -> Script Editor. In the Script Editor, add the following function to populate a spreadsheet with the results of an OData query:

function retrieve(){ var url = "https://MyUrl/api.rsc/incident?select=sys_id,sys_id,priority,category"; var response = UrlFetchApp.fetch(url,{ headers: {"Authorization": "Basic " + Utilities.base64Encode("MyUser:MyAuthtoken")} }); var json = response.getContentText(); var sheet = SpreadsheetApp.getActiveSheet(); var a1 = sheet.getRange('a1'); var index=1; var incident = JSON.parse(json).value; var cols = [["sys_id","sys_id","priority","category"]]; sheet.getRange(1,1,1,4).setValues(cols); row=2; for(var i in incident){ for (var j in incident[i]) { switch (j) { case "sys_id": a1.offset(row,0).setValue(account[i][j]); break; case "sys_id": a1.offset(row,1).setValue(account[i][j]); break; case "priority": a1.offset(row,2).setValue(account[i][j]); break; case "category": a1.offset(row,3).setValue(account[i][j]); break; } } row++; } }

Follow the steps below to add an installable trigger to populate the spreadsheet when opened:

  1. Click Resources -> Current Project's Triggers -> Add a New Trigger.
  2. Select retrieve in the Run menu.
  3. Select From Spreadsheet.
  4. Select On open.

After closing the dialog, you are prompted to allow access to the application.

You can test the script by clicking Publish -> Test as Add-On. Select the version, installation type, and spreadsheet to create a test configuration. You can then select and run the test configuration.
