You can read request body first and then append the parameters to object.

        <set-body>@{ 
        var requestBody = context.Request.Body.As<JObject>(preserveContent: 
        true);

        requestBody ["Content-Type"] = "Your Value";
        requestBody ["Accept"] = "Your Value";

        return requestBody.ToString();
        }</set-body>
