node-red upload attachment over http with token (multipart/form-data)

Question

I am lost recreating curl POST request in node red. My bank API documentation requires to form request like this:

multipart/form-data

curl -S -s --cacert GeoTrust_Primary_CA.pem -X POST -F "type=xml" -F "token=aGEMQB9Idh35fxxxxxxxxxxxxxQwyGlQ" -F "file=@C:\davka.xml" https://www.fio.cz/ib_api/rest/import/> result.xml 2>errorlog.txt type errorlog.txt

I really need just

curl -X POST -F "type=xml" -F "token=aGEMQB9Idh35fxxxxxxxxxxxxxQwyGlQ" -F "file=@C:\davka.xml" https://www.fio.cz/ib_api/rest/import/

However I am not able to pass the token to the form.

still get Required String parameter 'token' is not present

I failed with prefered http request or many node-red-contrib-send-form(...) variations.

My flow:

You should be able to do this with the core HTTP Request node. The issue is the format of the payload you are passing it.

If you change your Function node to structure the payload like this, I believe you should get further:


msg.payload = {
    "file": {
        "value": databuffer,
        "options": {
            "filename": "data.xml",
        }
    },
    "type": "xml",
    "token": "aGEMQB9Idh35fxxxxxfakexxxxxxxxQwyGlQ"
}
