Add security header to Webservice Request

We are invoking the Peoplesoft webservice from OSC.
PeopleSoft API contains the Authentication information in the security header like as below :
<SOAP-ENV:Header>
<wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd&quot; SOAP-ENV:mustUnderstand="1">
<wsse:UsernameToken>
<wsse:Username>User</wsse:Username>
<wsse:Password>Password</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</SOAP-ENV:Header>

How can this header information be included in the groovy script?
In groovy script , we are just able to view the Request payload without security information
