ASP.Net Core parse Stripe Webhook JSON Response

Question

I am working with Stripe/Stripe.net Webhooks in my ASP.Net Core app. I am trying to map an object where I can use the properties returned from the Webhook JSON response and save various properties into my database. Using Postman, I am able to receive the sample JSON that I got from Stripe test webhooks in my Controller method and parse the JSON using

var json = await new StreamReader(HttpContext.Request.Body).ReadToEndAsync();
Event stripeEvent = EventUtility.ParseEvent(json);

which returns:

stripeEvent = {<Stripe.Event@2269235 id=evt_00000000000000> JSON: {"id": "evt_00000000000000", "object": "event", "account": null, "api_version": "2020-03-02", "created": 1326853478, "data": {    "object": { "id": "ch_00000000000000", "...

I am needing to map the JSON from the RawObject ChildrenTokens into a model but I'm not able to access the ChildrenTokens through C#. Is there any way to be able to map these properties?

The trick here is to cast the stripeEvent.Data.Object as the specific class that the underlying event data should represent. Typically, you'll have a switch or if statement checking the stripeEvent.Type.

For instance, if the type of the event is payment_intent.succeeded, then the underlying data would be a PaymentIntent and you might have the following code to check the type, then cast to that type.

if (stripeEvent.Type == Events.PaymentIntentSucceeded)
{
  var paymentIntent = stripeEvent.Data.Object as PaymentIntent;
}

From there, you can interact with the paymentIntent and it's related properties.
