Difficulties sending multipart/form-data request via Postman

please, this is y concern: I'll like to know how to query a web service defined as in the below code using postman for test purposes.PS: I can't change the method signature

I have a web service like this :

@POST@Path("/uploadOpenAccountRequestFiles/{requestId}")@Consumes({MediaType.APPLICATION_JSON,MediaType.MULTIPART_FORM_DATA})public Response uploadOpenAccountRequestFiles(@PathParam("requestId") String requestId,        MultipartFormDataInput multipartFormDataInput)        throws JsonGenerationException, JsonMappingException, IOException {    initContext();    logger.info("DIGIBANK : uploadOpenAccountRequestFiles END: ");    String msge = "";    try {        digiBean.saveToserver(requestId, multipartFormDataInput);    } catch (Exception e) {        msge = e.getMessage();        e.printStackTrace();    }    org.af.webservice.Response resp = new org.af.webservice.Response(            request.getSession().getId(), "uploadOpenAccountRequestFiles", "",            msge.equalsIgnoreCase("OK") ? true : false, msge.equalsIgnoreCase("OK") ? false : true, "",            msge.equalsIgnoreCase("OK") ? true : false, "Boolean", msge);    logger.info("DIGIBANK : uploadOpenAccountRequestFiles END: ");    return Response.ok().entity(mapper.writeValueAsString(resp)).build();}
