Update a Data Extension with a Null Field Value

After assigning a value to a nullable field within a data extension, it may be necessary to return that field to a null value. When a call doesn't provide a value for a field in an update request, that field retains the current value. To overwrite the value of a field with a null value, the call must explicitly state that null value using the NullAPIProperty type.

Use these code examples to update a nullable field in a data extension to a null value.
