The Form Designer is a tool that allows you to create and customize forms on the ServiceNow platform. The Form Designer has four main components:

Form layout: The form layout shows the preview of the form and allows you to drag and drop fields, sections, and related lists onto the form. You can also resize, reorder, and delete the elements on the form layout.

Page header: The page header shows the name of the table and the form that you are editing. You can also access the form properties, save the form, and switch to the form view from the page header.

Field navigator: The field navigator shows the list of available fields for the table and allows you to search, filter, and add fields to the form. You can also create new fields and edit existing fields from the field navigator.

Schema map: The schema map is not part of the Form Designer. The schema map is a separate tool that shows the relationships between tables and fields on the platform. You can access the schema map from the System Definition > Tables module or from the context menu of a table.

Enabling “Allow access to this table via web services” allows authenticated users with proper roles to access this table via REST/SOAP APIs.

From Development Handbook 4.0.4, p. 191:

"This setting allows web service access to a table, but still requires that users have appropriate roles and permissions through ACLs."

Thus, access isn’t automatic — proper access controls still apply.

In ServiceNow, when configuring a REST Message, the Endpoint specifies the URI (Uniform Resource Identifier) where the REST request is sent. This URI points to the resource on the external system that the REST message will interact with, whether it's to retrieve, update, create, or delete data.

Key Points:

Endpoint Definition: The Endpoint is a complete URL that includes the protocol (e.g., HTTP or HTTPS), the domain or IP address of the external server, and the specific path to the resource. For example: https://api.example.com/v1/resources.

Dynamic Endpoints: ServiceNow allows the use of variables within the Endpoint URL, enabling dynamic substitution at runtime. This is useful when the exact resource path or parameters need to be determined during execution.

Configuration in ServiceNow:

Navigate to "System Web Services" > "Outbound" > "REST Message."

Create a new REST Message or select an existing one.

In the REST Message record, define the Endpoint URL in the "Endpoint" field.

Example Scenario:

If you are integrating ServiceNow with an external ticketing system to retrieve incident data, the Endpoint might be something like https://api.ticketingsystem.com/incidents/{incident_id}, where {incident_id} is a placeholder that gets replaced with the actual incident ID at runtime.

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. By selecting the Allow access to this table via web services option, you can enable other application scopes to access your data tables using web services, such as SOAP or REST. However, the user performing the query via web services must have the correct permissions to access the table’s records. The user must have the appropriate roles and access controls to perform the operations on the table, such as create, read, write, or delete.

The other statements are not true when this option is selected. This option does not restrict the ability to delete records via web services, nor does it allow records to be always read. The access to the records depends on the user’s permissions and the web service method. This option also does not restrict access only to SOAP web services, but applies to both SOAP and REST web services. Finally, this option is not the only way to enable web service access to the table’s records. Even when this option is not selected, users with the correct permissions can use web services to access the table’s records, as long as they specify the application scope in the web service request.
