Calling WSDL URL from service node

[anushka.parey]

Hello. I want to make call to a WSDL URL http://www.dneonline.com/calculator.asmx?wsdl using service node. However, after configuring the service node for GET/POST methods I always get an ESOCKETTIMEDOUT error with status code 400.
The URL works fine when tested with SOAP UI.

I’ve learnt from the documentation that WSDL URL can be used with Alert Tasks but setting an alert doesn’t serve me the purpose. Please help me to know if there is some other way of hitting a WSDL through kore.

Here are the snapshots of dialog configuration at service node, requested payload and expected response.

When you make a GET call to the WSDL end point (from a rest client like POSTMAN or servicenode from kore.ai bot builder), the response would show us the details like service endpoint (http://www.dneonline.com/calculator.asmx) to call, target namespace, operations allowed (Add, multiple, divide etc) and the elements that can be passed for performing these operations (intA, intB). Please refer to the highlighted elements in the response from in bold

Now on the bot builder, I have a dialog using the service http://www.dneonline.com/calculator.asmx that allows the users to perform these operations. Please refer to the below screenshots for details on the dialog configuration.

This content type for this service is expected in text/xml and so passing the headers

Configuring the request envelope for making the call

<?xml version="1.0" encoding="utf-8"?>

<soap:Envelope xmlns:soap=“http://schemas.xmlsoap.org/soap/envelope/”>
soap:Body
<{{context.entities.operation}} xmlns=“http://tempuri.org/”>
{{context.entities.firstNum}}
{{context.entities.secondNum}}
</{{context.entities.operation}}>
</soap:Body>
</soap:Envelope>

Screenshots of bot in action:

Hope this helps.

Also, the response that comes from the service in xml is converted to JSON by Kore.ai platform. So you could look up for the key in response object like context.calldneonline.response.body[“soap:Envelope”][“soap:Body”][0].AddResponse[0].AddResult[0]
