Use the HttpClient class provided in the System.Net.Http namespace.

using System.Net.Http;
using System.Threading.Tasks;

public async Task MakeApiCall()
{
    using var client = new HttpClient();
    var response = await client.GetAsync("https://example.com/api/endpoint");
    var content = await response.Content.ReadAsStringAsync();
    // Process the response content
}

using System.Net.Http;

using System.Threading.Tasks;

public async Task MakeApiCall()

    using var client = new HttpClient();

    var response = await client.GetAsync("https://example.com/api/endpoint");

    var content = await response.Content.ReadAsStringAsync();

    // Process the response content

In the above code, we create an instance of the HttpClient class and use the GetAsync method to make a GET request to the API endpoint. The response is then read as a string using the ReadAsStringAsync method of the response content. The content can then be processed as required by your application.
