Hello y'all,

I have created an app that uses Accept Hosted with redirect to Authorize.net payment page. Everything works great; I can make payments and the payment transactions are successful. The only thing I need now is to configure the app so that every time a payment occurs, it sends the transactions details back to my server. 

I know it has been suggested that I use webhooks to get notifications, but the thing I'm confused about webhooks is that it looks like I have to send GET request to the Authorize.net API in certain time intervals, rather than only when the transaction happens. I want to receive transaction details only after a payment happens and I don't want my server sending requests to the API continuously. 

I am using ASP.NET with C#. 

Any help or guidance is appreciated. Thank you!
