How to capture file upload Content from dsp page

hello @John_Carter4 and @srikanth.prathipati1803 is there any flow example to convert IData objects to multipart-formdata? i am quite confused to add each contents to the body part

Hi,

I might have one sample, I will check my archives and get back again.

So i want to generate this kind of message from IData, while this screenshot was made by request from postman

i want to transform this Json request that are transformed to IData when sent to the IS

{
"partnerReferenceNo":"1231231111",
"additionalInfo":{"channel":"MSM","deviceId":"VAMS"}
}

but i try to construct mimeData and addBodyPart the MimeData generated was wrong

"mimeData": {
        "headers": {
            "name": "JsonData"
        },
        "part": {
            "headers": {
                "1231231111": "1231231111",
                "content-transfer-encoding": "7bit",
                "content-type": "text/plain"
            },
            "part": {
                "smime": "false",
                "headers": {
                    "content-transfer-encoding": "7bit"
                },
                "content": "java.io.ByteArrayInputStream@41d5c6ff"
            }
        }

while i want generate message similar to this
