ServiceNow Connector for Talend Studio Allows the reading and writing of incidents, attachments, and more in ServiceNow without coding! The ZappySys ServiceNow API Connector provides easy-to-use, high-performance API access. In this article you will learn how to quickly and efficiently integrate ServiceNow data in Talend Studio without coding. We will use high-performance ServiceNow Connector to easily connect to ServiceNow and then access the data inside Talend Studio. Let's follow the steps below to see how we can accomplish that! Download Documentation ServiceNow Connector for Talend Studio is based on ZappySys API Driver which is part of ODBC PowerPack. It is a collection of high-performance ODBC drivers that enable you to integrate data in SQL Server, SSIS, a programming language, or any other ODBC-compatible application. ODBC PowerPack supports various file formats, sources and destinations, including REST/SOAP API, SFTP/FTP, storage services, and plain files, to mention a few.

Create Data Source in ZappySys Data Gateway based on API Driver

1. Download and install ODBC PowerPack.

2. Search for gateway in start menu and Open ZappySys Data Gateway:
   

3. Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
   

4. Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys API Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.

5. 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:

6. 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

   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

8. 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 Talend Studio 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.

9. 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 Talend Studio:

   --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).

10. Click OK to finish creating the data source.
