C# Authorize.net Create Profile Issue

The following code is charging the card, however it is not creating the profile....any tips? I'm assuming I'm missing something, or using the wrong Type...
var opaqueData = new opaqueDataType { dataDescriptor = "COMMON.ACCEPT.INAPP.PAYMENT", dataValue = paymentNonce };
//standard api call to retrieve response
var paymentType = new paymentType { Item = opaqueData };
var transactionRequest = new transactionRequestType
{
transactionType = transactionTypeEnum.authCaptureTransaction.ToString(), // authorize and capture transaction
amount = paymentAmount,
payment = paymentType,
customer = new customerDataType()
{
type = customerTypeEnum.individual,
id = userID.ToString()
},
profile = new customerProfilePaymentType()
{
createProfile = true
}
};
var request = new createTransactionRequest { transactionRequest = transactionRequest };
// instantiate the contoller that will call the service
var controller = new createTransactionController(request);
const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
ServicePointManager.SecurityProtocol = Tls12;
controller.Execute();
// get the response from the service (errors contained if any)
var response = controller.GetApiResponse();
UPDATE:
Since apparently OpaqueData is not allowed, I changed it to make the profile manually. I am getting the following Error: "Error: I00001 Successful."
// Add Payment method to Customer.
customerPaymentProfileType opaquePaymentProfile = new customerPaymentProfileType();
opaquePaymentProfile.payment = paymentType;
opaquePaymentProfile.customerType = customerTypeEnum.individual;
var request2 = new createCustomerPaymentProfileRequest
{
paymentProfile = opaquePaymentProfile,
validationMode = validationModeEnum.none,
customerProfileId = userID.ToString()
};
var controller2 = new createCustomerPaymentProfileController(request2);
controller2.Execute();
//Send Request to EndPoint
createCustomerPaymentProfileResponse response2 = controller2.GetApiResponse();
if (response2 != null && response2.messages.resultCode == messageTypeEnum.Ok)
{
if (response2 != null && response2.messages.message != null)
{
//Console.WriteLine("Success, createCustomerPaymentProfileID : " + response.customerPaymentProfileId);
}
}
else
{
Utility.AppendTextToFile("Error: " + response.messages.message[0].code + " " + response.messages.message[0].text, Server.MapPath("/pub/auth.txt"));
}
Update #2
Very confused as auth.net documentation says this code means success...so why don't I see the CIM payment method created??? RESPONSE CODE DOCS
Update #3
So I was printing out the main response message instead of the CIM request message, duh. The actual error was: "E00114 Invalid OTS Token."
Based on the the documentation, that error is usually from a used Key, so I am now generating 2 keys (One to process and One to store via CIM) but am now getting this error: "E00040 The record cannot be found."....Any ideas?

So the answer to this question is:
You can not auto create a payment profile using opaque card data, so the answer is to make it manually once you have a successful charge.
You can not use the same opaque card data to charge and store, as they are one time use, so for my web method I ended up passing 2 opaque data keys.
You have to make different calls for setting up a brand new customer and an existing customer just adding a new card. I have pasted an excerpt of my end solution below:
ApiOperationBase<ANetApiRequest, ANetApiResponse>.RunEnvironment = (System.Configuration.ConfigurationManager.AppSettings["Authorize-Live"].ToUpper() == "TRUE" ? AuthorizeNet.Environment.PRODUCTION : AuthorizeNet.Environment.SANDBOX);

C# : set default payment method in stripe

I am new in stripe, how can we set default payment method in stripe.
And can we pass cardId/sourceId to charge customer along with customerId.
Code:-
private static async Task<string> ChargeCustomer(string customerId)
{
return await System.Threading.Tasks.Task.Run(() =>
{
var myCharge = new StripeChargeCreateOptions
{
Amount = 50,
Currency = "gbp",
Description = "Charge for property sign and postage",
CustomerId = customerId
};
var chargeService = new StripeChargeService();
var stripeCharge = chargeService.Create(myCharge);
return stripeCharge.Id;
});
}
And 1 more question, how to get charge-list, I am using below code but getting exception(conversion error):-
private IEnumerable<StripeCharge> GetChargeList()
{
var chargeService = new StripeChargeService();
return chargeService.List();
}

This is what I ended up doing. Not sure why Stripe Checkout didn't set the card for the subscription setup as the default. Anyway, this fires triggered from the payment_intent.succeeded web hook. Sure there is a better way, but...
var customerService = new CustomerService(Configs.STRIPE_SECRET_KEY);
var c = customerService.Get(pi.CustomerId);
if (!string.IsNullOrEmpty(c.InvoiceSettings.DefaultPaymentMethodId)) {
status = "already has default payment method, no action";
hsc = HttpStatusCode.OK;
return;
}
var paymentMethodService = new PaymentMethodService(Configs.STRIPE_SECRET_KEY);
var lopm = paymentMethodService.ListAutoPaging(options: new PaymentMethodListOptions {
CustomerId = pi.CustomerId,
Type = "card"
});
if (!lopm.Any()) {
status = "customer has no payment methods";
hsc = HttpStatusCode.BadRequest;
return;
}
var pm = lopm.FirstOrDefault();
customerService.Update(pi.CustomerId, options: new CustomerUpdateOptions {
InvoiceSettings = new CustomerInvoiceSettingsOptions {
DefaultPaymentMethodId = pm.Id
}
});
hsc = HttpStatusCode.OK;
return;

We can pass cardId/BankAccountId/TokenId/SourceId in SourceTokenOrExistingSourceId property of StripeChargeCreateOptions,
private static async Task<string> ChargeCustomer(string customerId, string cardId)
{
try
{
return await System.Threading.Tasks.Task.Run(() =>
{
var myCharge = new StripeChargeCreateOptions
{
Amount = 50,
Currency = "gbp",
Description = "Charge for property sign and postage",
CustomerId = customerId,
SourceTokenOrExistingSourceId = cardId
};
var chargeService = new StripeChargeService();
var stripeCharge = chargeService.Create(myCharge);
return stripeCharge.Id;
});
}
catch(Exception ex)
{
return "";
}
}
To set/change default payment method:-
public void ChangeDefaultPayment(string customerId, string sourceId)
{
var myCustomer = new StripeCustomerUpdateOptions();
myCustomer.DefaultSource = sourceId;
var customerService = new StripeCustomerService();
StripeCustomer stripeCustomer = customerService.Update(customerId, myCustomer);
}
Still looking for how to get charge-list.

How to Update campaign in Bing Ads?

For Update campaign I am using this Code
public async Task<List<long?>> updateCampaign(Campaign campaign,string status)
{
try
{
campaign.Status = (CampaignStatus)(int)Enum.Parse(typeof(CampaignStatus), status);
var request = new UpdateCampaignsRequest
{
Campaigns = new Campaign[] { campaign },
CustomerId = "xxxxxx",
UserName = "something#outlook.com",
Password = "something#123",
ApplicationToken = "myApplicationToken",
CustomerAccountId = "123456",
DeveloperToken = "1234567890"
};
CampaignService = new ServiceClient<ICampaignManagementService>(_authorizationData);
CampaignService.RefreshOAuthTokensAutomatically = false;
var result = (await CampaignService.CallAsync((s, r) => s.UpdateCampaignsAsync(r), request));
if (result.TrackingId != null)
{
return result.CampaignIds.ToList();
}
else
{
return new List<long?>();
}
}
catch (Exception ex)
{
ErrorLog.log(ex);
return new List<long?>();
}
}
When I run this code, I got this error "Invalid client data. Check the SOAP fault details for more information"
thanks.

For updating the Campaign we can use "BulkServiceManager" for bulk updating of the campaign,you can use this service single campaign update also.
public async Task<List<long?>> updateCampaign(List<Campaign> campaigns)
{
try
{
var listBulkCampaign = new List<BulkCampaign>();
foreach (var campaign in campaigns)
{
var _bulkCampaign = new BulkCampaign()
{
Campaign = campaign
};
listBulkCampaign.Add(_bulkCampaign);
}
BulkServiceManager bulkServiceManager = new BulkServiceManager(_authorizationData);
string fileName = bingCampaignUpdate.csv;
var campaigns = (await bulkServiceManager.UploadEntitiesAsync(new EntityUploadParameters
{
Entities = listBulkCampaign,
OverwriteResultFile = true,
ResultFileDirectory = FileDirectory,
ResultFileName = fileName,
ResponseMode = ResponseMode.ErrorsAndResults
})).OfType<BulkCampaign>().ToList();
return new List<long?>();
}
catch (Exception ex)
{
ErrorLog.log(ex);
return new List<long?>();
}
}
You have to download .csv report and update the Campaigns.
I hope it helps you

I believe the issue is that JSONResponse() doesn't know how to serialize a Dictionary<string,object> to a valid JSON format.
Take a look at some of these answers to help you solve this problem. Most of them suggest using a JSON library like JSON.NET:
https://stackoverflow.com/a/6620173/2344773
https://stackoverflow.com/a/5597628/2344773

i have already added JSON.NET to my project and JSONResponse() function
private string JSONResponse(bool success, string message, object data = null)
{
var dictionary = new Dictionary<string, object> { { "success", success }, { "message", message }, { "data", data } };
return JsonConvert.SerializeObject(dictionary, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
}
