SOAP advice - Fusion Cloud

Summary:

Hi Team,

Getting error when trying update IdentifyingAddressFlag to N using SOAP service. Does anyone know how to update the IdentifyingAddressFlag using SOAP.

Error "401 Unauthorized" when attempting to run SOAP request to set IdentifyingAddressFlag to "N" using /crmService/FoundationPartiesPersonService?WSDL

I am running the request payload below but am consistently getting the error message "401 Unauthorized" via Postman client. 

<soap:Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">

<soapenv:Body>

<mergePerson xmlns="http://xmlns.oracle.com/apps/cdm/foundation/parties/personService/applicationModule/types/">

<typ:personParty>

<per:PartyId>10000000</per:PartyId>

<per:PartySite>

<par:PartySiteId>10000009</par:PartySiteId>

<par:IdentifyingAddressFlag>false</par:IdentifyingAddressFlag>
