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)

Requirements

This article assumes that you have full filled following basic requirements.

1. Download Install ZappySys ODBC PowerPack (API Driver for ServiceNow included)
2. Install Informatica PowerCenter Client Tools (e.g. Workflow and Mapping Designers)
3. Access to a Relational database such as SQL Server (or use any of your choice e.g. Oracle, MySQL, DB2 ). If nothing available then you can use flat file target.

High level Steps for Import ServiceNow data using Informatica (Read ServiceNow API data)

Video Tutorial – Read any API / JSON data in Informatica (Load ServiceNow to SQL Table)

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 ODBC Data Source (DSN) based on ZappySys API Driver

Step-by-step instructions

To get data from ServiceNow using Informatica we first need to create a DSN (Data Source) which will access data from ServiceNow. We will later be able to read data using Informatica. Perform these steps:

1. Download and install ODBC PowerPack.

2. Open ODBC Data Sources (x64):

   

3. Create a User data source (User DSN) based on ZappySys API Driver

   ZappySys API Driver

   
   • Create and use User DSN if the client application is run under a User Account. This is an ideal option in design-time, when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit.
   • Create and use System DSN if the client application is launched under a System Account, e.g. as a Windows Service. Usually, this is an ideal option to use in a production environment. Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.

4. 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

   ServiceNow

   

5. Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.

    Basic Auth [Http]

   Authenticate using ServiceNow instance username and password.

   Steps how to get and use ServiceNow credentials
   

   Locate your ServiceNow instance credentials and use them for HTTP authentication:

   1. Go to https://developer.servicenow.com/dev.do and log in.
   2. Click on your profile picture.

   3. When a menu appears, click on Manage instance password or a similar option:

      

   4. In a new window you will see your HTTP Basic Authentication credentials:

      

   5. Done! Use this username and password when configuring OAuth Authentication parameters.

   Fill in all required parameters and set optional parameters if needed:

   ServicenowDSN

   ServiceNow

   Basic Auth [Http]

   https://[$InstanceName$].service-now.com/api/now

   Required Parameters
   InstanceName	Fill-in the parameter...

   RetryStatusCodeList	429
   RetryCountMax	5
   RetryMultiplyWaitTime	True

   

    OAuth [OAuth]

   Authenticate using ServiceNow instance username, password, OAuth Client ID, and Client Secret. [API reference]

   Steps how to get and use ServiceNow credentials
   

   Create OAuth application and use it for authentication:

   1. Login to your instance at https://your-instance-id.service-now.com.

   2. Start by clicking on menu item All, then search for oauth, and click Application Registry option:

      

   3. Then click button New:

      

   4. Continue by clicking Create an OAuth API endpoint for external clients option:

      

   5. Move on by naming your OAuth application and entering a Client Secret (or let it be generated automatically).

   6. Finally give it a final touch by increasing the Refresh Token Lifespan value to 315,360,000 (it should last for 10 years):

      

   7. Done! Now you can use Client ID and Client Secret when configuring OAuth Authentication parameters.

   Fill in all required parameters and set optional parameters if needed:

   ServicenowDSN

   ServiceNow

   OAuth [OAuth]

   https://[$InstanceName$].service-now.com/api/now

   ServicenowDSN

   

7. Start by selecting the Table or Endpoint you are interested in and then configure the parameters. This will generate a query that we will use in Informatica to retrieve data from ServiceNow. Hit OK button to use this query in the next step.

   SELECT * FROM incident 
   
   --Using Primary Key				
   --SELECT * FROM any_table_here WHERE sys_id='109562a3c611227500a7b7ff98cc0dc7' --Primary Key in WHERE clause
   
   --Using Filter Expression
   --SELECT * FROM incident WITH(Query='number=INC0000001') --Equal condition
   --SELECT * FROM incident WITH(Query='number!=INC0000001') --Not equal condition
   --SELECT * FROM incident WITH(Query='numberININC0000001,INC0000002,INC0000003') --IN condition
   --SELECT * FROM incident WITH(Query='number=INC0000001^state=7') --AND condition
   --SELECT * FROM incident WITH(Query='number=INC0000001^ORnumber=INC0000002') --OR condition
   --SELECT * FROM incident WITH(Query='numberLIKE0001') --LIKE condition
   --SELECT * FROM incident WITH(Query='numberSTARTSWITHINC00') --StartWith condition
   --SELECT * FROM incident WITH(Query='numberENDSWITH0001') --StartWith condition
   --SELECT * FROM incident WITH(Query='number=INC0000001^state=7^NQORnumber=INC0000002') --AND / OR MIXED using NQ (NewQuery Operator)  -- (number=INC0000001 and state=7) OR (number=INC0000002)
   
   --more information about filter here https://docs.servicenow.com/bundle/utah-platform-user-interface/page/use/common-ui-elements/reference/r_OpAvailableFiltersQueries.html
   
   
   -- To read all available tables execute this query:
   -- SELECT * FROM Tables
   
   -- Other common tables:
   -----------------------
   -- SELECT * FROM sys_db_object
   -- SELECT * FROM sys_dictionary
   -- SELECT * FROM sys_user
   -- SELECT * FROM sys_user_has_role
   -- SELECT * FROM sys_user_grmember
   -- SELECT * FROM task
   -- SELECT * FROM task_sla
   -- SELECT * FROM incident
   -- SELECT * FROM incident_sla
   -- SELECT * FROM change_request
   -- SELECT * FROM cmdb_ci_computer
   -- SELECT * FROM cmdb_ci_outage
   -- SELECT * FROM cmdb_ci
   -- SELECT * FROM sn_customerservice_case
   -- SELECT * FROM kb_knowledge
   -- SELECT * FROM kb_use
   -- SELECT * FROM sc_req_item
   -- SELECT * FROM sc_request
   -- SELECT * FROM sc_task

   
   Some parameters configured in this window will be passed to the ServiceNow API, e.g. filtering parameters. It means that filtering will be done on the server side (instead of the client side), enabling you to get only the meaningful data much faster.

8. Now hit Preview Data button to preview the data using the generated SQL query. If you are satisfied with the result, use this query in Informatica:

   --Using Filter Expression
   --SELECT * FROM incident WITH(Query='number=INC0000001') --Equal condition
   --SELECT * FROM incident WITH(Query='number!=INC0000001') --Not equal condition

   --more information about filter here https://docs.servicenow.com/bundle/utah-platform-user-interface/page/use/common-ui-elements/reference/r_OpAvailableFiltersQueries.html
   
   
   -- To read all available tables execute this query:
   -- SELECT * FROM Tables
   
   -- Other common tables:
   -----------------------
   -- SELECT * FROM sys_db_object
   -- SELECT * FROM sys_dictionary
   -- SELECT * FROM sys_user
   -- SELECT * FROM sys_user_has_role
   -- SELECT * FROM sys_user_grmember
   -- SELECT * FROM task
   -- SELECT * FROM task_sla
   -- SELECT * FROM incident
   -- SELECT * FROM incident_sla
   -- SELECT * FROM change_request
   -- SELECT * FROM cmdb_ci_computer
   -- SELECT * FROM cmdb_ci_outage
   -- SELECT * FROM cmdb_ci
   -- SELECT * FROM sn_customerservice_case
   -- SELECT * FROM kb_knowledge
   -- SELECT * FROM kb_use
   -- SELECT * FROM sc_req_item
   -- SELECT * FROM sc_request
   -- SELECT * FROM sc_task

   
   You can also access data quickly from the tables dropdown by selecting <Select table>.
   A WHERE clause, LIMIT keyword will be performed on the client side, meaning that the whole result set will be retrieved from the ServiceNow API first, and only then the filtering will be applied to the data. If possible, it is recommended to use parameters in Query Builder to filter the data on the server side (in ServiceNow servers).

9. Click OK to finish creating the data source.

8. That’s it, we are now ready to perform similar steps to import Target table structure in the next section.

Import SQL Server Target Definition in Informatica Mapping Designer

Now let’s look at steps to import Target table definition (very similar to the previous section, the only difference is this time we will select DSN which points to SQL Server or any other Target Server).

Now lets look at steps to import target table definition in Informatica mapping designer.

1. In the Mapping Designer, Click on Target Icon to switch to Target designer
2. From the top menu > Click on Targets > Import from Database …
3. Select DSN for your Target server (if DSN doesn’t exist then create one by opening ODBC Sources just like we created one for JSON API source (see the previous section about creating DSN).

4. Enter your userid , password and Schema name and click Connect to see tables
5. Select Table name to and click OK import definition.
   

   Import Target SQL Table Definition in Informatica – Select table from the list

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.

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

   Define Source to Target mapping for ServiceNow to SQL Table load in Informatica

5. 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')

6. Once you done with mapping save your mapping and name it (i.e. m_Api_To_SQL)
7. Now lets move to next section to create workflow.

Create Workflow and Session in Informatica

Now the final step is to create a new workflow. Perform following steps to create workflow which with a session task to import JSON data into SQL table.

1. Open workflow designer by click [W] icon.
2. Launch new workflow creation wizard by click Workflow top menu >  Wizard
   name your workflow (e.g. wf_Api_Tp_Sql_Table_Import)
