sending POST request to azure ML Web service using poster

I have successfully deployed a web service using Azure ML and am able to get output both on Azure ML as well as a sample R client application.

I would like to however get response using the firefox poster.

I have followed the instructions from the Azure page on deploying the web service and tried using the same request headers and parameters as follows

Instructions from azure page enter image description here

this is what I've tried on Poster enter image description here enter image description here

Error message enter image description here

My R Code which works

library("RCurl")
library("rjson")

# Accept SSL certificates issued by public Certificate Authorities
options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))

h = basicTextGatherer()
hdr = basicHeaderGatherer()


req = list(

        Inputs = list(


            "input1" = list(
                "ColumnNames" = list("Smoker", "GenderCD", "Age"),
                "Values" = list( list( "1", "M", "8" ),  list( "1", "M", "8" )  )
            )                ),
        GlobalParameters = setNames(fromJSON('{}'), character(0))
)

body = enc2utf8(toJSON(req))
api_key = "hHlKbffejMGohso5yiJFke0D9yCKwvcXHG8tfIL2d8ccWZz8DN8nqxh9M4h727uVWPz+jmBgm0tKBLxnPO4RyA=="
authz_hdr = paste('Bearer', api_key, sep=' ')

h$reset()
curlPerform(url = "https://ussouthcentral.services.azureml.net/workspaces/79f267a884464b6a95f5819870787918/services/e3490c06c73849f8a78ff320f7e5ffbc/execute?api-version=2.0&details=true",
            httpheader=c('Content-Type' = "application/json", 'Authorization' = authz_hdr),
            postfields=body,
            writefunction = h$update,
            headerfunction = hdr$update,
            verbose = TRUE
            )

headers = hdr$value()
httpStatus = headers["status"]
if (httpStatus >= 400)
{
    print(paste("The request failed with status code:", httpStatus, sep=" "))

    # Print the headers - they include the requert ID and the timestamp, which are useful for debugging the failure
    print(headers)
}

print("Result:")
result = h$value()
print(fromJSON(result))

My API key

hHlKbffejMGohso5yiJFke0D9yCKwvcXHG8tfIL2d8ccWZz8DN8nqxh9M4h727uVWPz+jmBgm0tKBLxnPO4RyA==

How can I form a correct URL which works?

The "Content to Send" section is incorrect, you have specified URL-encoded, while you need to put application/json.
