Generate IRN Code
RestClient client = new RestClient("https://gstsandbox.charteredinfo.com/eicore/dec/v1.03/Invoice?QrCodeSize=250");
RestRequest request = new RestRequest(Method.POST);
request.AddHeader("Gstin", "<---->");
request.AddHeader("user_name", "<---->");
request.AddHeader("AuthToken", "<----->");
request.AddHeader("aspid", "<------>");
request.AddHeader("password", "<------>");
// Need to pass Either value "1" OR "2" in Header
request.AddHeader("irpurl", "1");//Used By gsp
request.AddHeader("irpurl", "2");//Used By gsp
request.AddHeader("password", "<------>");
request.AddHeader("Content-Type", "application/json; charset=utf-8");
request.RequestFormat = DataFormat.Json;
request.AddBody(reqPlGenIRN); //Request Payload in object format
IRestResponse response = await client.ExecuteTaskAsync(request);
RespPlGenIRNDec respPlGenIRN = new RespPlGenIRNDec();
respPlGenIRN = JsonConvert.DeserializeObject<RespPlGenIRNDec>(response.Content);
//code to save QR image
byte[] qrImg = Convert.FromBase64String(respPlGenIRN.QrCodeImage);
TypeConverter tc = TypeDescriptor.GetConverter(typeof(Bitmap));
Bitmap bitmap1 = (Bitmap)tc.ConvertFrom(qrImg);
bitmap1.Save(@"C:\Users\Pallavi\Desktop\qr.png");
NOTE: If you wat just NIC Response and not using the Parsed Response that TaxPro GSP Returns in fields ExtractedSignedInvoiceData, ExtractedSignedQRCode, and QrCodeImage, please use query parm ParseIrnResp=0. This would prevent parsing of response and speed-up the API Response.
