Clearing values from a target instance

Pass an empty value through a SOAP parameter to clear the respective value in the target instance.

In addition to passing specific values in a SOAP request to update the values in a target instance, you can also pass an empty (null) value through the &allow_empty_value=true SOAP query parameter to clear the respective value in the target instance.

For example, https://<instance name>.service-now.com/incident.do?SOAP&allow_empty_value=true lets you pass an empty value to the incident record in an instance.

You can then enter lines like the following in the SOAP request:
<assigned_to>value</assigned_to>
<assignment_group>value</assignment_group>
<category></category>
In the above example,
  • <assigned_to>value</assigned_to> changes the value in the Assigned to field to the value specified in the SOAP request.
  • <assignment_group>value</assignment_group> changes the value in the Assignment group field to the value specified in the SOAP request.
  • <category></category> clears the value in the Category field.
