Creating SOAP request from JSON array

[pradeep3j]

I have JSON request with array that needs to be sent as SOAP request in back end. Can anyone please help that how can I construct repeated occurrence in SOAP message

JSON:

{
  "requestList": [{
    "accountLevel": "CL",
    "accountPortfolio": "01",
    "account": "608859577"
  }, {
    "accountLevel": "CL",
    "accountPortfolio": "01",
    "account": "607364694"
  }]
}

SOAP

<soap:Envelope 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:ns1="urn:2DD4107F-4052-491E-8D41-FBDE9171A2EF">
  
  <soap:Body>
    <ns1:RequestName>
      <ns1:item> 
        <ns1:accountLevel>CL</ns1:accountLevel>
        <ns1:accountPortfolio>01</ns1:accountPortfolio>
        <ns1:account>608859577</ns1:account> 
      </ns1:item> 
      <ns1:item>
        <ns1:accountLevel>CL</ns1:accountLevel>
        <ns1:accountPortfolio>01</ns1:accountPortfolio>
        <ns1:account>607364694</ns1:account> 
      </ns1:item>
    </ns1:RequestName>
  </soap:Body>

</soap:Envelope>

I could do for 1 occurrence by parsing the JSON request in JavaScript policy and stored the request elements in variables. I used Assign Message policy to construct SOAP payload by inserting those variables.

But this logic will not work if there are multiple dynamic occurrences in request as I cannot write conditional logic in Assign Message policy.

How can I accomplish this?

FTFY. I took the liberty to reformat your code and add some things to the SOAP example.

• Your JSON was not valid, as it did not include surrounding curly braces.
• Your soap example was a snippet, as it did not include the Envelope or Body elements, both of which are required in a SOAP request.

first, use a json to xml policy on the request.content, this dynamically works on n number of array elements. Then use a javascript to replace the proper namespace on the new content. replace the existing content with new.

Here's an example that

• uses JSONToXML to transform the original JSON into XML
• Uses XSL to transform the XML into XML with the right form and namespaces, embedded into a SOAP envelope.

For an input of

{
  "requestList": [{
    "accountLevel": "CL",
    "accountPortfolio": "01",
    "account": "608859577"
  }, {
    "accountLevel": "CL",
    "accountPortfolio": "01",
    "account": "607364694"
  }]
}

The output is:

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:ns1="urn:2DD4107F-4052-491E-8D41-FBDE9171A2EF"
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns1:RequestElement>
         <ns1:item>
            <ns1:accountLevel>CL</ns1:accountLevel>
            <ns1:accountPortfolio>01</ns1:accountPortfolio>
            <ns1:account>608859577</ns1:account>
         </ns1:item>
         <ns1:item>
            <ns1:accountLevel>CL</ns1:accountLevel>
            <ns1:accountPortfolio>01</ns1:accountPortfolio>
            <ns1:account>607364694</ns1:account>
         </ns1:item>
      </ns1:RequestElement>
   </soap:Body>
</soap:Envelope>

...which I think is what you wanted.

Thanks, its perfectly working for me. I appreciate your help for such a faster resoution

You're very welcome, I'm glad to help! Unfortunately the solution involves XSL, which is not everyone's favorite language. But when you are dealing with XML, XSL is a good tool for the job.
