Hello @nj_prnd ,
You can try setting the <wsa:To>
header in following manner.
<set-body template="liquid">
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns="http://tempuri.org/" >
<soap:Header xmlns:wsa="http://www.w3.org/2005/08/addressing">
<wsa:To>https://message-dev.abc.org.au/Services/Iwap.svc</wsa:To>
</soap:Header>
<soap:Body>
</soap:Body>
</soap:Envelope>
</set-body>
Please let me know if there are any additional concerns, I will be glad to continue with our discussion. Thank you!
