Data Manager Fields

You will need to specify the following information from Assets Data Manager:

1. Name - the name of the Connection, visible as the job name in Adapters.

2. Object - the name of the Object Class you want to the data to be loaded into.

3. Data Source Name - the type of data being created; which is usually the tool name, e.g AD, Qualys etc. Note: This can be the same as Name.

4. Data Source Type - what type of data is the tool providing? For example, Assets, CMDB, user location and more.

ServiceNow Fields

You will need to specify the following information from ServiceNow:

1. Authentication Type - type of Authentication to connect to the ServiceNow API. ServiceNow supports Basic and OAuth methods of authentication.

2. API URL - the ServiceNow instance URL to enable Data Manager to connect to the ServiceNow source

3. Source Table\View Name - name of the table or view as defined in ServiceNow from which to retrieve the records

4. API limit - maximum number of records to return. Allows the enforcement of the amount of request/quantity of data (or records) to be consumed by the Data Manager Adapters. By default, the API limit is set to 0 meaning that there are no restrictions, however if connecting to a ServiceNow source that is heavily populated with data, the best practice is to limit the rate to 1000.

5. API fields - comma-separated list of field names to return in the response. This feature restricts the number of fields returned from the source.

6. API query - an encoded query string used to filter the results. It performs the query on a specific field in the source table and returns the query results to the staging.

If you are using Basic Auth, complete the following fields:

1. Username - name to generate the authorization token.

2. Password - password to generate the authorization token.

3. Basic Authentication Token - encoded base-64 string used in authorization of Service-Now API access.

If you are using OAuth, complete the following fields:

1. Username - name to generate the authorization token.

2. Password - password to generate the authorization token.

3. Client secret - a unique identifier to generate the authorization token.

4. Client-ID - a secret string that the application uses to prove it's identity when requesting a token.

Authentication and Authorization

The connector requires user authentication within the ServiceNow tenancy and must have the following:

• Read only access to the required tables / database views

• rest_api_explorer role

API Call

Fields Retrieved

The most common tables consumed for ServiceNow include:
