            try
            {
                CollectTransactionRequestFinal c = new CollectTransactionRequestFinal()
                {
                    requestMsg = requestString,
                    pgMerchantId = <Your Key>
                };
                var bodyJson = JsonConvert.SerializeObject(c);
                var stringContent = new StringContent(bodyJson, Encoding.UTF8, "application/json");
                using (var handler = new HttpClientHandler())
                {
                    // allow the bad certificate
                    handler.ServerCertificateCustomValidationCallback = (request, cert, chain, errors) => true;
                    using (var httpClient = new HttpClient(handler))
                    {
                       var r= await httpClient.PostAsync(url, stringContent);
                       var result = await r.Content.ReadAsStringAsync();
                        return new ApiResponse
                        {
                            statusCode = "",//response.StatusCode.ToString(),
                            Response = result

                    }
                }
                
            }
            catch (Exception ex)
            {
                
            }
        }

 

Other ways....

 

HttpClientHandler clientHandler = new HttpClientHandler();
clientHandler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };

// Pass the handler to httpclient(from you are calling api)
HttpClient client = new HttpClient(clientHandler);
