We are running an App with a Angular/Typescript frontend and a .NET backend, using Stripe Elements and Stripe.NET respectively.
We are currently using the "Sources" API.
The frontend can create sources, the backend saves them to our specific users. When you open the frontend again, the backend sends a list of source ids. The frontend then collects the data it needs to display those sources directly from Stripe so the user can pick one of his saved sources to pay and does not have to enter all the data again.
Enter the Payment Method / Payment Intend API.
Due to EU regulations Stripe has a new API that requires us to create cards no longer as "source" but as a "PaymentMethod". So I implemented that in the backend, opened the frontend in my IDE, updated the #types/stripe-v3 package and found the new payment intent API.
The only thing missing: I cannot figure out how the frontend is to access the payment method data, once created. I can create it. Send it to the backend. The backend can retrieve it. Send back the ID to the frontend... and now what? How to display the payment methods available?
I had expected a stripe.retrievePaymentMethod() as there is a stripe.retrieveSource(). But no such luck.
The only option I currently see to present the user with a list of existing payment methods is getting this info on the backend and piping it all, class by class, property by property to the client. Basically copying every single data class stripe has into our own backend REST definition. That cannot be right.
What am I missing? Why is there no stripe.retrievePaymentMethod() on the frontend? Did I not understand some fundamental facts about what those APIs should do?
After contacting Stripe directly, it was confirmed that that's just the way it is:
I think it's just an oversight that we didn't add one.
There are similar functions in the mobile SDK so I don't see why we shouldn't have it
There are no immediate plans to add the functionality back in in the very near future,
so as a workaround, I will tunnel all the data through our backend(s).
If I understand as well, I think your problem is following and the sequence of that. I hope this helps you.
I have implemented a payment gateway like ccAvenue with DotNet and angular, in my case, I send the data to the server, and from the server, I tried to redirect to the payment gateway, but APIs return some result, and the result can not be redirected.
So I created a web-form with implementation, I redirected my app to web-forms page and from there I called the ccAvenue page, and in the response URL, I send the response page of webforms only and after saving the response I redirected to my angular app.
Here is workaround if you want to process 3Dsecure cards and still support other methods like SEPA.
You could attach both, confirmed PaymentIntent (payment method) or Source to the Customer object.
On your frontend you could implement both (StripeElements with client secret for 3Dsecure cards) and IBAN element for SEPA.
I could provide my code example how I save payment intent to the customer. It's in PHP, but for other languages logic should be the same.
Assuming that our client already confirmed PaymentIntent and we have it's id:
$intent = \Stripe\PaymentIntent::retrieve($stripe_intent_id);
$payment_method = \Stripe\PaymentMethod::retrieve($intent->payment_method);
$stripe_customer = Stripe\Customer::create([
'payment_method' => $intent->payment_method,
]);
In case you've already created Customer object before you could use attach method:
$payment_method->attach(['customer' => 'cus_FTkGe4lv5LfyI0']);
Then you'll be able to charge using Customer object PaymentMethod or Source;
I didn't try to attach both methods to the same customer object (we only allow customer to have one payment option at the same time), but it should work. Let me know if it works for you.

I am new to StackOverflow, struggling to find a solution to my problem: I am trying to synchornize my asp.net app with the calendly api.
So far, I have managed to create a webhook subscription and I saw that the webhooks are being registered to https://calendly.com/api/v1/hooks/ and I was able to acces a specific webhook using its id (I used Postman to see all this, as I am currently local developing). I am having a lot of trouble since I am not able to understand what call should I make in order to get the webhooks and be able to use their data in my app.
https://developer.calendly.com/docs/sample-webhook-data
This is what I should be parsing, according to Calendly documentation.
I want to get data such as the emails of those participing into the event, also the date and status of the event. How can I do this?
From your question, it seems to me there might be a lack of conceptual understanding of what webhooks are.
As you mention, you had already subscribed to be notified if some event happens in Calendly (I assume invitee.created event).
This means, that
when this event actually happens on Calendly (you may need to make a test scheduling request in the Calendly UI), the notification about this event is sent to the URL you had registered (subscribed).
This registered URL has to be reachable for the notification call. In other words, if the URL is in your local environment (and you mentioned it is so), it's impossible for the notification to reach the registered (subscribed) destination. So this might be the issue you're experiencing.
You need to read incoming raw data. In my script, with PHP, I do it using file_get_contents('php://input')
You need to parse the data. With PHP I use json_decode($inputData). In your language you've got to use whatever tools you have for JSON parsing.
Basically, that's it. In my case, I read invitee email using $parsedData->payload->invitee->email.
Hope it helps.
I have been tasked to implement a JIRA SMS notification(using Twilio) similar to its in-built email notification. I know this can be easily done using Zapier and Twilio.
But i am told to look for a workaround with out using Zapier.
The only option i think of now is to create a WebApi project that calls Twilio to send the SMS, host the WebApi project on a server and pass this URL as a WEBHOOK in JIRA.
For this i have created a C# class library which calls Twilio.
class
and after that i have added a new WebApi project for this solution and added the above class project reference.
and i have added a new controller:
controller
i am just calling the send method from the constructor with out any parameters which i think will do the job just from hardcoded number to a given number(in the controller.
but what i need is to pass in messageBody and recipientPhoneNumber from the JIRA webhook to this controller. Not sure how to do this.
As i am very new to WebApi's could some one please help me with the code. much appreciated.
Twilio Dev Evangelist here...
Mind dropping me a note at corey#twilio.com? I agree with the previous responses - this site may not be the best forum to support what you're looking for here, but I would be more than happy to directly help you out here.
but what i need is to pass in messageBody and recipientPhoneNumber from the JIRA >webhook to this controller. Not sure how to do this.
The way webhooks work is a little bit different than your assumption above. You cannot pass anything to JIRA webhook. JIRA POSTs data to the webhook (your API URL). Once you receive the data in your API controller action, you can construct a message body and recipient phone number (from e.g. user object passed in by JIRA; if that object doesn't have any phone number attribute, you might have to use a custom field).
As i am very new to WebApi's could some one please help me with the code. much appreciated.
No problem. I guess you have done the Twilio part alright already. Please visit MS docs to know more about Web API. You have to add a controller method so that it can be called by JIRA. So your final URL becomes this. You can then put this URL in JIRA as webhook. Replace hostname mycompany.com by your server hostname and change other url segments based on your situation.
For some days now i have been struggling on a project where i need to provide a URL to enable me to receive a JSON response(precisely this my first time of calling a web API)
This is the scenario:
- First the company has a web service that i need to consume and send a bill prompt to our client and so far it has been successful
- Second , they ask me to implement a callback and give them the URL where they will call me to send the status of the bill whether our client has confirm the bill prompt or not(this is where i am stacked)
When i get the JSON data i can easily use it to do what i want but my problem is how to implement the web page that the company will call to send the status.
Please a sample code will help me a lot.Thanks
What you are trying to achieve is called WebAPI. You expose HTTP endpoints using Controllers to the Internet and consumers of your API may utilize them to POST the status back.
You are describing creating an API. Basically, you create an endpoint url using a controller in C#. It's within this controller that you receive data from "the company" and process it, and do whatever you need to do after that. If you use the standard MVC framework build into C#, it's fairly straight-forward. Here is an example of a callback url we are using in a three-legged OAuth procedure. The last step involves a third party sending a request to our callback url and posting some data. We are using a model as a parameter. But you can use simple structures (int, string, etc) as well. As log as the names of your params match the names that the third party sends in their query string or POST, the MVC framework will handle the variable assignment automatically. The serialization/deserialization is built in to the framework.
Here is a small example of how we have implemented a callback url in one of our apps:
public class MyAuthenticatedController : Controller
{
public ActionResult Index([FromUri]MyAuthenticatedModel model)
{
logTheResponse(model);
if (model == null)
{
throw new HttpException(401, "Auth Failed");
}
}
}
The third party would hit the url:
http://app.mydomain.com/myauthenticated
Using the GET method.
If you don't want to build an ASP.NET Web API Project, you can do this easily with an Azure Function.
See: https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-generic-webhook-triggered-function
I'm developing a jQuery website that will display a single record from my Azure Table Storage (ATS) account. I don't want to use jQuery to directly access the table, since that would require disclosure of my ATS account name and key in the jQuery code. I've tried to find a simple C# web service example project that would be the interface, but everything I can find is much more complicated than I need.
This web service will need just one API that jQuery will use: it will be passed two strings: the Partition Key and the Row Key for ATS, which will exactly match with an existing record in ATS. The result returned will be a string that jQuery will convert using JSON.parse() after it is received. If no record is found with the Partition and Row Keys passed in, an empty string should be returned.
If you know of an example of a simple C# web service that I could use as a starting point, I would greatly appreciate a link to it. It's been many years since I developed with C#, and the complicated nature of the table service API with all the associated crypto, hashing, signatures, etc. have left me confused.
Edit: I now realize that maybe both my jQuery code (providing the web UI) and the C# (providing the ATS interface) might work together in one .NET solution. I'm currently running the jQuery UI app standalone in its own .NET solution, due to my path of fumbling around trying things out.
I don't want to use jQuery to directly access the table, since that would require disclosure of my ATS account name and key in the jQuery code.
It seems that you do not want jQuery client directly make a GET request to query entity via table service Rest API, and you’d like to create a backend service for querying entity in table. As maccettura mentioned in comment, you can create a ASP.NET Web API project and do Query Entities operation in controller action.
[Route("queryentity/{pk}/{rk}")]
public CustomerEntity Get(string pk, string rk)
{
//you can install [Azure Storage Client Library for .NET](https://www.nuget.org/packages/WindowsAzure.Storage/)
//and then create a retrieve operation and pass both partition and row keys to retrieve a single entity
//TableOperation retrieveOperation = TableOperation.Retrieve<CustomerEntity>(pk, rk);
//or
//make [Query Entities](https://learn.microsoft.com/en-us/rest/api/storageservices/query-entities) operation as you did
return myCustomerEntity;
}
On an existing host I've added Web API Models & Controllers. I've added the following four:
Products
Orders
Categories
Users
When someone accesses the localhost:port\api\products, it returns all the products in JSON format.
The Create, Update and Delete statements are completely disabled, so we are only able to use GET-requests on the API (so either \api\products for a list of all products or api\products\# for a single products with id #).
Because the other CRUD's aren't used, there isn't a lot of security that should be added to the Web API, except for one thing: The Users
These will also return emails and such, which would be better to keep private and unreadable without the proper authorization (without entire log-in pages, but a way to authenticate yourself when accessing the Web API in for example Android HttpGetRequests).
So, the question: How should I add authorization for only the UsersController accessed by the Web API.
And, how can I encrypt the JSON in C# and decrypt it in Android again. If this second part is too big to answer I'll make a new question later on, my main focus is the low-end [<- without log-in pages, so built in into the GET-request] authorization of the Web API's GET-request for Users.
Edit 1: I did found this link where a new project is made with Authorization Changed to Individual Users. I also see that the user is registered and then logged in with POST and GET requests.
The following questions came into mind when reading through this link:
How to change the Web API's Authorization to Individual Users on an existing project?
Our authorization is done through OAuth (mainly Google-account) with our work e-mail address. I guess it's not possible / easy to authorize in the same way as in the link with a Google-account on Web API GET-requests.
Edit 2: After using the first link provided by Vladimir Gondarev I've added the [Authorize] to both the Get methods in the UsersController. In my project everything else was already used before, like a class that uses the AuthorizeAttribute, so just adding the [Authorize] was already enough for the first step. Now in the browser I get an unauthorized (JSON) back when I'm not logged in, which is good.
The next step would be to add the OAuth-authorization to the Android app, but that is an entire new problem / question that I will look into first before asking a new stackoverflow-question.
The simplest solution would be "Basic Authentification". In order to to implement it you have to derive from AuthorizeAttribute and then apply it to a method or a controller.
Here you find further info:

ASP.net Web API RESTful web service + Basic authentication
You don't have to encrypt anything as long as you use HTTPS transport.
