ServiceNow ITOM connector and actionedit

The ServiceNow ITOM connector uses the event API to create ServiceNow events. You can use the connector for rule actions.

Prerequisitesedit

Create a ServiceNow integration useredit

To ensure authenticated communication between Elastic and ServiceNow, create a ServiceNow integration user and assign it the appropriate roles.

  1. In your ServiceNow instance, go to System Security → Users and Groups → Users.
  2. Click New.
  3. Complete the form, then right-click on the menu bar and click Save.
  4. Go to the Roles tab and click Edit.
  5. Assign the integration user the following roles:

    • personalize_choices: Allows the user to retrieve Choice element options, such as Severity.
    • evt_mgmt_integration: Enables integration with external event sources by allowing the user to create events.
  6. Click Save.
Create an RSA keypair and add an X.509 Certificateedit

This step is required to use OAuth for authentication between Elastic and ServiceNow.

Create an RSA keypair:

  1. Use OpenSSL to generate an RSA private key:

    openssl genrsa -out example-private-key.pem 3072
    openssl genrsa -passout pass:foobar -out example-private-key-with-password.pem 3072 

    Use the passout option to set a password on your private key. This is optional but remember your password if you set one.

  2. Use OpenSSL to generate the matching public key:

    openssl req -new -x509 -key example-private-key.pem -out example-sn-cert.pem -days 360

Add an X.509 certificate to ServiceNow:

  1. In your ServiceNow instance, go to Certificates and select New.
  2. Configure the certificate as follows:

    • Name: Name the certificate.
    • PEM Certificate: Copy the generated public key into this text field.
    Shows new certificate form in ServiceNow
  3. Click Submit to create the certificate.
Create an OAuth JWT API endpoint for external clients with a JWT Verifiers Mapedit

This step is required to use OAuth for authentication between Elastic and ServiceNow.

  1. In your ServiceNow instance, go to Application Registry and select New.
  2. Select Create an OAuth JWT API endpoint for external clients from the list of options.

    Shows application type selection
  3. Configure the application as follows:

    • Name: Name the application.
    • User field: Select the field to use as the user identifier.
    Shows new application form in ServiceNow

    Remember the selected user field. You will use this as the User Identifier Value when creating the connector. For example, if you selected Email for User field, you will use the user’s email for the User Identifier Value.

  4. Click Submit to create the application. You will be redirected to the list of applications.
  5. Select the application you just created.
  6. Find the Jwt Verifier Maps tab and click New.
  7. Configure the new record as follows:

    • Name: Name the JWT Verifier Map.
    • Sys certificate: Click the search icon and select the name of the certificate created in the previous step.
    Shows new JWT Verifier Map form in ServiceNow
  8. Click Submit to create the verifier map.
  9. Note the Client ID, Client Secret and JWT Key ID. You will need these values to create your ServiceNow connector.

Connector configurationedit

ServiceNow ITOM connectors have the following configuration properties.

Name
The name of the connector.
Is OAuth
The type of authentication to use.
URL
ServiceNow instance URL.
Username
Username for HTTP Basic authentication.
Password
Password for HTTP Basic authentication.
User Identifier
Identifier to use for OAuth type authentication. This identifier should be the User field you selected during setup. For example, if the selected User field is Email, the user identifier should be the user’s email address.
Client ID
The client ID assigned to your OAuth application.
Client Secret
The client secret assigned to your OAuth application.
JWT Key ID
The key ID assigned to the JWT verifier map of your OAuth application.
Private Key
The RSA private key generated during setup.
Private Key Password
The password for the RSA private key generated during setup, if set.

Connector networking configurationedit

Use the Action configuration settings to customize connector networking configurations, such as proxies, certificates, or TLS settings. You can set configurations that apply to all your connectors or use xpack.actions.customHostSettings to set per-host configurations.

Preconfigured connector typeedit

Connector using Basic Authentication

 my-servicenow-itom:
   name: preconfigured-servicenow-connector-type
   actionTypeId: .servicenow-itom
   config:
     apiUrl: https://example.service-now.com/
   secrets:
     username: testuser
     password: passwordkeystorevalue

Connector using OAuth

 my-servicenow:
   name: preconfigured-oauth-servicenow-connector-type
   actionTypeId: .servicenow-itom
   config:
     apiUrl: https://example.service-now.com/
     usesTableApi: false
     isOAuth: true
     userIdentifierValue: testuser@email.com
     clientId: abcdefghijklmnopqrstuvwxyzabcdef
     jwtKeyId: fedcbazyxwvutsrqponmlkjihgfedcba
