Documentation

Introduction

JSON / REST API is becoming more and more popular each day as everyone embrace cloud-centric services. This article is primarily focused on Informatica users who want to access ServiceNow data or may be other API Integration in Informatica. However many tips and techniques described in this article will help you to understand how to integrate ServiceNow / XML SOAP / JSON / REST API in other ETL / Reporting apps such as Tableau, Power BI, SSRS, Talend, Excel and many more.

After going through this article you will learn how to Read ServiceNow / JSON / REST API data in Informatica and understand the concept of JSON / REST API. We will go through many screenshots and step-by-step examples to demonstrate ServiceNow or REST API integration in Informatica PowerCenter.

XML / JSON can come from a local file or REST API service (internal or public) so we will include both examples in this article (i.e. Read JSON files in Informatica, Import REST API in Informatica). So let’s get started. Next article will focus on how to write data to API in Informatica (POST / PUT data)

If you need to consume API which is not listed on connector library page then please refer to the below article links. It talks about how to read / write pretty much any API and not just ServiceNow API. It explains various API tips / tricks using our other Universal Drivers not mentioned in this article (i.e. ZappySys JSON / XML and CSV Drivers).

By watching following ~5 min video can learn steps listed in this article to load JSON API data into SQL Server Table using ZappySys JSON Driver. You can go though full article to learn many useful details not covered in this video.

Getting Started – Import ServiceNow to SQL Server in Informatica

Now let’s get started. For example purpose, we will read data from ServiceNow and load data into SQL Server Table using Informatica Workflow.

Create data source using ServiceNow ODBC Driver

Step-by-step instructions

To get data from ServiceNow using Informatica PowerCenter, we first need to create an ODBC data source. We will later read this data in Informatica PowerCenter. Perform these steps:

Download and install ODBC PowerPack (if you haven't already).
Search for odbc and open the ODBC Data Sources (64-bit):
Create a User data source (User DSN) based on the ZappySys API Driver driver:

ZappySys API Driver
- Create and use a User DSN if the client application runs under a User Account. This is the ideal option at design time (e.g., when developing in Visual Studio). Use it for both types of applications (64-bit and 32-bit).
- Create and use a System DSN if the client application runs under a System Account (e.g., as a Windows Service). This is usually the required option in a production environment. If your Windows Service is a 32-bit application, you must use the 32-bit ODBC Data Source Administrator to configure this
When the Configuration window appears give your data source a name if you haven't done that already, then select "ServiceNow" from the list of Popular Connectors. If "ServiceNow" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:

ServicenowDSN

Create Source to Target Mapping in Informatica (Import JSON to SQL Server)

Once you have imported source and target table definition, we can create mapping and transformation to load data from JSON to SQL Table.

First open Mapping Designer (Click [D] icon)
Drag JSON Source from sources folder
Drag SQL Table from Targets folder
Map desired columns from Source to target

Define Source to Target mapping for ServiceNow to SQL Table load in Informatica
For certain columns you may have to do datatype conversion. For example to convert OrderDate form nstring to DataTime you have to use Expression Transform like below and map it to target. In below example, our JSON has date format (e.g. 2018-01-31 12:00:00 AM ). To import this to DateTime field in SQL server we need to convert it using TO_DATE function. Use double quotes around T to make this format working.
```
TO_DATE(OrderDate,'YYYY-MM-DD H12:MI:SS AM')

 --For ISO use below way
        TO_DATE(OrderDate,'YYYY-MM-DD"T"HH24:MI:SS')
```

Optional: Centralized data access via ZappySys Data Gateway

In some situations, you may need to provide ServiceNow data access to multiple users or services. Configuring the data source on a Data Gateway creates a single, centralized connection point for this purpose.

This configuration provides two primary advantages:

Centralized data access
The data source is configured once on the gateway, eliminating the need to set it up individually on each user's machine or application. This significantly simplifies the management process.
Centralized access control
Since all connections route through the gateway, access can be governed or revoked from a single location for all users.

	Data Gateway	Local ODBC data source
Simple configuration
Installation	Single machine	Per machine
Connectivity	Local and remote	Local only
Connections limit	Limited by License	Unlimited
Central data access
Central access control
More flexible cost

To achieve this, you must first create a data source in the Data Gateway (server-side) and then create an ODBC data source in Informatica PowerCenter (client-side) to connect to it.

Let's not wait and get going!

Create ServiceNow data source in the gateway

In this section we will create a data source for ServiceNow in the Data Gateway. Let's follow these steps to accomplish that:

Search for gateway in the Windows Start Menu and open ZappySys Data Gateway Configuration:
Go to the Users tab and follow these steps to add a Data Gateway user:
- Click the Add button
- In the Login field enter a username, e.g., john
- Then enter a Password
- Check the Is Administrator checkbox
- Click OK to save
Now we are ready to add a data source:
- Click the Add button
- Give the Data source a name (have it handy for later)
- Then select Native - ZappySys API Driver
- Finally, click OK
ServicenowDSN

ZappySys API Driver
When the ZappySys API Driver configuration window opens, go back to ODBC Data Source Administrator where you already have the ServiceNow ODBC data source created and configured, and follow these steps on how to Import data source configuration into the Gateway:
- Open ODBC data source configuration and click Copy settings:
  
  ZappySys API Driver - Configuration [Version: 2.0.1.10418]
  
  ZappySys API Driver - ServiceNow
  
  Read and write ServiceNow data effortlessly. Integrate, manage, and automate incidents, tasks, attachments, and records — almost no coding required.
  
  ServicenowDSN
- The window opens, telling us the connection string was successfully copied to the clipboard:
- Then go to Data Gateway configuration and in data source configuration window click Load settings:
  
  ServicenowDSN
  
  ZappySys API Driver - Configuration [Version: 2.0.1.10418]
  
  ZappySys API Driver - ServiceNow
  
  Read and write ServiceNow data effortlessly. Integrate, manage, and automate incidents, tasks, attachments, and records — almost no coding required.
  
  ServicenowDSN
- Once a window opens, just paste the settings by pressing CTRL+V or by clicking right mouse button and then Paste option.
Once done, go to the Network Settings tab and Add a firewall rule for inbound traffic:
- This will initially allow all inbound traffic.
- Click Edit IP filters to restrict access to specific IP addresses or ranges.
Crucial Step: After creating or modifying the data source, you must:
- Click the Save button to persist your changes.
- Hit Yes when prompted to restart the Data Gateway service.
This ensures all changes are properly applied:

Skipping this step may cause the new settings to fail, preventing you from connecting to the data source.

Create ODBC data source to connect to the gateway

In this part we will create an ODBC data source to connect to the ZappySys Data Gateway from Informatica PowerCenter. To achieve that, let's perform these steps:

Search for odbc and open the ODBC Data Sources (64-bit):
Create a User data source (User DSN) based on the ODBC Driver 17 for SQL Server driver:

ODBC Driver 17 for SQL Server

If you don't see the ODBC Driver 17 for SQL Server driver in the list, choose a similar version.
Then set a Name for the data source (e.g. Gateway) and the address of the Data Gateway:

ZappySysGatewayDSN

localhost,5000

Make sure you separate the hostname and port with a comma, e.g. localhost,5000.
Proceed with the authentication part:
- Select SQL Server authentication
- In the Login ID field enter the user name you created in the Data Gateway, e.g., john
- Set Password to the one you configured in the Data Gateway
Then set the default database property to ServicenowDSN (the one we used in the Data Gateway):

ServicenowDSN

ServicenowDSN

Make sure to type the data source name manually or copy/paste it directly into the field. Using the dropdown might fail because the Trust server certificate option is not enabled yet (next step).
Continue by checking the Trust server certificate option:
Once you do that, test the connection:
If the connection is successful, everything is good:
Done!

We are ready to move to the final step. Let's do it!
