### Answer by Yash Srivastava

Integrating OpenAI API with [ASP.NET](https://www.mindstick.com/articles/257/ajax-toolkit-calendarextender-control-in-asp-dot-net) Core Application means developers send Request to AI model through [.NET](https://answers.mindstick.com/blog/204/machine-learning-with-dot-net-a-complete-guide-for-developers) Backend and get Intelligent response from there. which can help to add some features like Chatbots, content Generator, Smart Search or Automation Features.

Steps which have to be followed is:

**1. Get API keys :** Get an API key from OpenAI Dashboard.

**2. Store API Key Securely :** store API keys using appsettings.json, Environment variables, etc.

```cs
"OpenAI": {
  "ApiKey": "Use_Your_API_Here"
}
```

**3. Create AI Service Class :** It handles AI API call, Response process, clean Controller, etc.

example:

```cs
public class AIService
{
   public string GetAIResponse(string userMessage)
   {
       return "AI reply for: " + userMessage;
   }
}
```

## 4. Register in Program.cs :

```cs
builder.Services.AddHttpClient<OpenAIService>();
```

**5. Create Controller:** In ASP.NET core a Controller handles incoming HTTP requests, process them and send response.

```cs
using Microsoft.AspNetCore.Mvc;
public class HomeController : Controller
{
   public IActionResult Index()
   {
       return Content("Hello from Controller");
   }
}
```
