I don't know if this is the issue but I've run into an issue in the past where even though you pass the parameters in with keyword syntax, the function takes in the parameters in order. So you would want to pass in {paramNames, paramValues, headerNames, headerValues, body, user, etc}

I am looking for post method which is not supported by a!httpQuery() function.

We used a!httpQuery as mentioned in the below link and it is working fine for us.

I think you need to format your value as a dictionary. Try using this: a!toJson({value:{clientId: "FRA5001939", invoiceType: "Domino's Food"}})

Thanks Josh,
I am using tojason method to make request body but getting Type value error.

Expression evaluation error at function 'httppostwithresponse' [line 13]: Error evaluating function 'httppostwithresponse' : The passed parameter(s) are of the wrong type. Received the type com.appiancorp.common.xml.JaxbConversionException: JAXB was not able to produce a value for typed value TypedValue[it=94,v={TypedValue[it=3,v=clientId]=TypedValue[it=3,v=FRA5001939], TypedValue[it=3,v=invoiceType]=TypedValue[it=3,v=Domino's Food]}] as java class java.lang.Long.

Modified code:

load(
local!requestBody: a!toJson(value:{ "clientId":"FRA5001939", "invoiceType":"Domino's Food"}),
httppostwithresponse(
endpoint: "http://XX.XX.XX.XX:9090/ws/rest/OSA_API/getUnpaidFoodInvoicesByUnit",
paramNames: {},
paramValues: {},
headerNames: {},
headerValues: {},
user: null,
password: null,
domain: null,
timeout: "60",
body: local!requestBody
)

)

a!httpwrite() returns a writer function and will not return a result. (docs.appian.com/.../fnc_connector_http_a_httpwrite.html)

httppostwithresponse() from the shared component "Send HTTP Request Plug-in" should help you out. forum.appian.com/.../summary

Hi vahluwalia,
Give try like this, Declare load variable for body part because the first blank argument will be filled with the value being saved into the variable.
local!body:a!toJson(
{
"clientId": "FRA501",
"invoiceType": "Food"
}
)

/////////////////////////////////////
a!buttonWidget(
label: "start",
value:local!body,
saveInto:local!count
)
