Consume ServiceNow OData Feeds in SAP Lumira
Use the API Server to create data visualizations on ServiceNow feeds that reflect any changes in SAP Lumira.
You can use the CData API Server to create data visualizations based on ServiceNow data in SAP Lumira. The API Server enables connectivity to live data: dashboards and reports can be refreshed on demand. This article shows how to create a chart that is always up to date.
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
If you have not already done so, download the CData API Server. Once you have installed the API Server, follow the steps below to begin producing secure ServiceNow OData services:
Connect to ServiceNow
To work with ServiceNow data from SAP Lumira, we start by creating and configuring a ServiceNow connection. Follow the steps below to configure the API Server to connect to ServiceNow data:
- First, navigate to the Connections page.
-
Click Add Connection and then search for and select the ServiceNow connection.
-
Enter the necessary authentication properties to connect to ServiceNow.
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.
- After configuring the connection, click Save & Test to confirm a successful connection.
Configure API Server Users
Next, create a user to access your ServiceNow data through the API Server. You can add and configure users on the Users page. Follow the steps below to configure and create a user:
- On the Users page, click Add User to open the Add User dialog.
-
Next, set the Role, Username, and Privileges properties and then click Add User.
-
An Authtoken is then generated for the user. You can find the Authtoken and other information for each user on the Users page:
Creating API Endpoints for ServiceNow
Having created a user, you are ready to create API endpoints for the ServiceNow tables:
-
First, navigate to the API page and then click
Add Table
.
-
Select the connection you wish to access and click Next.
-
With the connection selected, create endpoints by selecting each table and then clicking Confirm.
Gather the OData Url
Having configured a connection to ServiceNow data, created a user, and added resources to the API Server, you now have an easily accessible REST API based on the OData protocol for those resources. From the API page in API Server, you can view and copy the API Endpoints for the API:
Connect to ServiceNow from SAP Lumira
Follow the steps below to retrieve ServiceNow data into SAP Lumira. You can execute an SQL query or use the UI.
- In SAP Lumira, click File -> New -> Query with SQL. The Add New Dataset dialog is displayed.
- Expand the Generic section and click the Generic OData 2.0 Connector option.
-
In the Service Root URI box, enter the OData endpoint of the API Server. This URL will resemble the following:
https://your-server:8080/api.rsc
-
In the User Name and Password boxes, enter the username and authtoken of an API user. These credentials will be used in HTTP Basic authentication.
Select entities in the tree or enter an SQL query. This article imports ServiceNow incident entities.
-
When you click Connect, SAP Lumira will generate the corresponding OData request and load the results into memory. You can then use any of the data processing tools available in SAP Lumira, such as filters, aggregates, and summary functions.
Create Data Visualizations
After you have imported the data, you can create data visualizations in the Visualize room. Follow the steps below to create a basic chart.
In the Measures and Dimensions pane, drag measures and dimensions onto the x-axis and y-axis fields in the Visualization Tools pane. SAP Lumira automatically detects dimensions and measures from the metadata service of the API Server.
By default, the SUM function is applied to all measures. Click the gear icon next to a measure to change the default summary.
- In the Visualization Tools pane, select the chart type.
- In the Chart Canvas pane, apply filters, sort by measures, add rankings, and update the chart with the current ServiceNow data.
