Use Anypoint Studio to Configure ServiceNow Connector 6.7 - Mule 4

Anypoint Studio (Studio) editors help you design and update your Mule applications, properties, and configuration files.

To add and configure a connector in Studio:

When you run the connector, you can view the app log to check for problems, as described in View the App Log.

If you are new to configuring connectors in Studio, see Use Studio to Configure a Connector. If, after reading this topic, you need additional information about the connector fields, see the ServiceNow Connector Reference.

Create a Mule Project

In Studio, create a new Mule project in which to add and configure the connector:

  1. In Studio, select File > New > Mule Project.

  2. Enter a name for your Mule project and click Finish.

Add the Connector to Your Mule Project

Add ServiceNow Connector to your Mule project to automatically populate the XML code with the connector’s namespace and schema location and to add the required dependencies to the project’s pom.xml file:

  1. In the Mule Palette view, click (X) Search in Exchange.

  2. In the Add Dependencies to Project window, type servicenow in the search field.

  3. Click ServiceNow Connector in Available modules.

  4. Click Add.

  5. Click Finish.

Adding a connector to a Mule project in Studio does not make that connector available to other projects in your Studio workspace.

Configure a Source

A source initiates a flow when a specified condition is met. You can configure one of these input sources to use with ServiceNow Connector:

  • HTTP > Listener
    Initiates a flow each time it receives a request on the configured host and port

  • Scheduler
    Initiates a flow when a time-based condition is met

For example, to configure an HTTP Listener, follow these steps:

  1. In the Mule Palette view, select HTTP > Listener.

  2. Drag Listener to the Studio canvas.

  3. On the Listener configuration screen, optionally change the value of the Display Name field.

  4. Specify a value for the Path field.

  5. Click the plus sign (+) next to the Connector configuration field to configure a global element that can be used by all instances of the HTTP Listener in the app.

  6. On the General tab, specify the connection information for the connector.

  7. On the TLS tab, optionally specify the TLS information for the connector.

  8. On the Advanced tab, optionally specify reconnection information, including a reconnection strategy.

  9. Click Test Connection to confirm that Mule can connect with the specified server.

  10. Click OK.

Add a Connector Operation to the Flow

When you add a connector operation to your flow, you immediately define a specific operation for that connector to perform.

To add an operation for ServiceNow Connector, follow these steps:

  1. In the Mule Palette view, select ServiceNow and then select the desired operation.

  2. Drag the operation onto the Studio canvas and to the right of the input source.

Configure a Global Element for the Connector

When you configure a connector, it’s best to configure a global element that all instances of that connector in the app can use. Configuring a global element requires you to provide the authentication credentials that the connector requires to access the target ServiceNow system. ServiceNow Connector supports Basic and OAuth2 authentication types.

To configure the global element for ServiceNow Connector, follow these steps:

  1. Select the operation in the Studio canvas.

  2. In the configuration screen for the operation, click the plus sign (+) next to the Connector configuration field to access the global element configuration fields.

  3. On the General tab, in Connection, select the authentication method to configure:

  4. On the Advanced tab, optionally specify reconnection information, including a reconnection strategy.

  5. Click Test Connection to confirm that Mule can connect with the specified server.

  6. Click OK.

Basic Authentication

  1. In the ServiceNow Config General tab, select Basic Authentication from the Connection drop-down list.

  2. Provide the following values for Basic authentication:

    Field Description

    Username

    Name used to log in to ServiceNow

    Password

    Password that corresponds to the user name

    Service Address

    The WSDL endpoint

    ServiceNow Version

    The ServiceNow version to use

    User table list

    Custom tables for a user who is logged in

    The global element connection settings with basic authentication selected
  3. Click OK.

Basic Authentication HTTP Message Dispatcher Provider

  1. Click the Transport tab.

  2. From Transport Configuration, select Basic auth http message dispatcher provider.

  3. Enter the following required values:

Field Description

User Name

Name used to log in to ServiceNow

Password

Password that corresponds to the user name

Basic Authentication HTTP Requester Based Transport Provider

  1. Click the Transport tab.

  2. From Transport Configuration, select Http requester based transport provider.

  3. Select the Requester config or click the green plus sign to create a new one.

    The Transport configuration tab for basic authentication
  4. Specify the required values:

Field Description

Host

The WSDL endpoint

Username

User name for logging in to ServiceNow

Password

Password that corresponds to the user name

OAuth2.0 Authentication

  1. In the ServiceNow Config General tab, select OAuth 2.0 Authorization Code from the Connection drop-down list.

  2. Specify the values for the OAuth connection:

General tab for configuring OAuth 2.0 Authorization Code authentication
Field Description

Service Address

ServiceNow’s instance endpoint.

Consumer key

Client ID from the registered application.

Consumer secret

Client secret from the registered application.

Authorization url

Endpoint for initiating the OAuth dance.

Access token url

Endpoint for retrieving the access token.

Listener config

HTTP Listener configuration.

Callback path

The path of the access token callback endpoint.

Authorize path

The path of the local HTTP endpoint that triggers OAuth dance.

External callback url

If the callback endpoint is behind a proxy or should be accessed through a non-direct URL, use this parameter to specify the URL the OAuth provider should use to access the callback.

View the App Log

To check for problems, you can view the app log as follows:

  • If you’re running the app from Anypoint Platform, the output is visible in the Anypoint Studio console window.

  • If you’re running the app using Mule from the command line, the app log is visible in your OS console.

Unless the log file path is customized in the app’s log file (log4j2.xml), you can also view the app log in the default location MULE_HOME/logs/<app-name>.log.

Next Step

After configuring ServiceNow Connector in Studio, see the Examples to experiment with the connector.
