How to create a Visa RTM Web Service request message

[Manu_Ashok]

Hi Experts

We recently got access to the Visa RTM Web service end point URL from our client. We installed the necessary certificates and credentials, but now when try to access the URL (from browser & also through postman), we get the attached error. 

<?xml version='1.0' ?>
<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
    <env:Body>
        <env:Fault>
            <faultcode>env:Client</faultcode>
            <faultstring>Internal Error</faultstring>
        </env:Fault>
    </env:Body>
</env:Envelope>

We went through the Getting started document and got to know that there is a specific way to access the Web service. The document describes in a conceptual view about the header (which should contain the necessary credentials) and the body which should contain the actual RTM request.  From above it seems, we are not able to create a possible handshake. Could any of you help us in creating a relevant request (SOAP/XML) that can help us access these APIs.

Hi Diana

We indeed received a .pfx file from client and the endpoint URL is https://mutualcertservicesgateway.visa.com/websrv_rtm/v7/RTMService/mte

Along with this we also received a Visa Online login and credentials. Is this platform different from the sandbox url & endpoint that you have mentioned in your reply.
