We can't tell you, because we don't know how the API expects you to pass the username and password. You'll need to ask the PHP developer to provide more details.

I need the way in asp.net to get this data from API as per the URL they gave me with Basic Authentication.
I don't think this related to the PHP developer because he gave the URL to get the JSON file.

Please update me

There's the missing information - you need to use Basic authentication[^].

How to use Basic Authentication to get data from JSON file ??
and what is the missing information ?

It depends on the class you're using to load the file. A Google search for the class name + "basic authentication" should show you what you need to do.

I don't know what is the class I should use to get the data

Assuming you're on a recent version of .NET, try the HttpClient Class[^].

C#

string TargetUrl = "..."; // The URL of the page you want to load
string Username = "...";  // The username you were told to use
string Password = "...";  // The associated password

var client = new HttpClient();
var byteArray = Encoding.ASCII.GetBytes(Username + ":" + Password);
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

using (var response = await client.GetAsync(TargetUrl))
{
    response.EnsureSuccessStatusCode();
    
    string json = await response.Content.ReadAsStringAsync();
    ... DO SOMETHING WITH THE JSON HERE ...
}

If you're using .NET Framework 4.5 or 4.6, you'll need to add a reference to the NuGet package:
NuGet Gallery | System.Net.Http 4.3.4[^]
