Converting One Data Type Object to another Data Type Object in WSO2 Config Lang

Question

I am trying to convert one json payload to another, I have tried using DataMapper but the output payload does not match the input payload so I can't map both data.

I tried with enrich mediator but I can't seem to find my way through.

input json

{
    "requestID": "10001",
    "requestMode": "mode34",
    "channelCode": "34",
    "agentBusinessName": "34",
    "agentNumber": "34",
    "agentInstitutionCode": "001",
    "agentAccountNumber": "098788"
}

output json

{
    "BalanceEnquiryRequest": {

        "channel": null,
        "type": "mode34",
        "customerId": "098788",
        "customerIdType": null,
        "submissionTime": null,
        "reqTranId": "10001",
        "passcode": null
    }
}

If it is just a single BalanceEnquiryRequest you can use the PayloadFactory mediator.

<payloadFactory media-type="json">
    <format>
        {
            "BalanceEnquiryRequest": {
                "channel": null,
                "type": $1,
                "customerId": $2,
                ... etc
            }
        }
    </format>
    <args> 
        <arg evaluator="json" expression="$.requestMode"/>
        <arg evaluator="json" expression="$.agentAccountNumber"/>
        ... etc
    </args>
<payloadFactory>
