ServiceNow Connector 6.16 Examples - Mule 4

To fully benefit from using Anypoint Connector for ServiceNow (ServiceNow Connector), see the following examples.

Retrieve Records from a ServiceNow Incident Table

This example creates a Mule flow that retrieves records from the Incident table. The following screenshot shows the Studio app flow for this example:

ServiceNow flow for incident get records
Figure 1. App flow for the Retrieve Records example
  1. Create a Mule project in Studio.

  2. Add and configure an HTTP Listener trigger for your flow with this path:

    getrecords

    HTTP Listener general settings with path set to getrecords
  3. Add a Transform Message component after the HTTP connector and provide a transformation script similar to this:

    %dw 2.0
    output application/xml
    ns ns0 http://www.service-now.com/incident
    ---
    {
    	ns0#getRecords: {
    		ns0#description: 'Test WSDL QA'
    	}
    }
    Add a description that matches records in your ServiceNow incident table.
  4. Add the Invoke operation from ServiceNow after the Transform component.

  5. Set up, test, and save a ServiceNow configuration for the connection to the ServiceNow server. If the connection is unsuccessful, correct any invalid connection parameters, and test again.

  6. In the General tab in the navigation, set Service to incident and Operation to getRecords.

  7. Optionally, choose Show Reference Values from the values (ALL, TRUE, FALSE)

    In Studio 7.5.0 and later, you can choose the service and operation keys without specifying the Show Reference Values key to resolve the metadata. However, in earlier Studio versions, metadata won’t be loaded until you specify all of the metadata keys, and if you don’t specify all of the metadata keys, it results in a tooling exception.

  8. Set the Message Body to payload.

  9. Add the Transform Message component to transform XML to JSON for better readability. For example:

    %dw 2.0
    output application/json
    ---
    payload
  10. Add a Logger component to the end of your flow that takes a payload (or #[payload]) as the message.

  11. Deploy or run your app.

  12. Test the app by navigating to http://localhost:8081/getrecords

The response should look similar to this example (several fields are omitted for brevity):

{
  "headers": {

  },
  "attachments": {

  },
  "body": {
    "getRecordsResponse": {
      "getRecordsResult": {

        "approval": "not requested",
        "business_stc": "0",
        "calendar_stc": "0",
        "category": "Software",
        "child_incidents": "0",
        "description": "Test WSDL QA",
        "escalation": "0",
        "hold_reason": "0",
        "impact": "1",

        "opened_by": "6816f79cc0a8016401c5a33be04be441",
        "order": "0",
        "priority": "1",
        "reassignment_count": "0",
        "reopen_count": "0",
        "severity": "3",
        "state": "1",
        "sys_class_name": "incident",
        "sys_created_by": "admin",
        "sys_created_on": "2019-09-20 07:30:34",
        "sys_domain": "global",
        "sys_domain_path": "/",
        "sys_id": "c03deab4db840010a0e6e04a48961999",
        "sys_mod_count": "47",

        "upon_reject": "cancel",
        "urgency": "1",
      }
    }
  }
}

If you use ALL for Show Reference Values, the response is similar to this abbreviated output, in which the response element name for the display value field begins with dv:

{
  "headers": {

  },
  "attachments": {

  },
  "body": {
    "getRecordsResponse": {
      "getRecordsResult": {
        "active": "1",
        "dv_active": "true",
        "activity_due": "2020-05-07 13:14:19",
        "dv_activity_due": "2020-05-07 06:14:19",
        "additional_assignee_list": null,
        "dv_additional_assignee_list": null,
        "approval": "not requested",
        "dv_approval": "Not Yet Requested",
      }
    }
  }
}

The response element name for the display value field is prefixed with dv.

Retrieve ServiceNow Incident Table Keys

This example creates a Mule flow that retrieve keys from the Incident table in a ServiceNow instance:

  1. Create a Mule application as a project in Studio.

  2. Add and configure an HTTP Listener trigger for your flow, and set the Path to /getkeys.

  3. Add a Transform Message component after the HTTP Listener operation.

  4. Provide a transformation script similar to this (use a description that matches records in your ServiceNow incident table):

    %dw 2.0
    output application/xml
    ns ns0 http://www.service-now.com/incident
    ---
    {
    	ns0#getKeys: {
    		ns0#description: 'Test WSDL QA'
    	}
    }
  5. Add the ServiceNow Invoke operation after the Transform Message component.

  6. Set up, test, and save a ServiceNow configuration for the connection to the ServiceNow server. If the connection is unsuccessful, correct any invalid connection parameters and test again.

  7. In the General tab navigation, set Service to incident and Operation to getKeys.

  8. Set the Message Body to payload.

  9. Add the Transform Message component to transform XML to JSON for better readability. For example:

    %dw 2.0
    output application/json
    ---
    payload
  10. Add a Logger component to the end of your flow that takes a payload (or #[payload]) as the message.

  11. Deploy or run your app.

  12. To test the app, navigate to: http://localhost:8081/getkeys

  13. The response should look similar to this:

    {
      "headers": {
    
      },
      "attachments": {
    
      },
      "body": {
        "getKeysResponse": {
          "sys_id": "c03deab4db840010a0e6e04a48961999,0f517ab8db840010a0e6e04a489619bc,6f1236f8db840010a0e6e04a489619f5",
          "count": "3"
        }
      }
    }
