I have coded in the StartUp.cs the following code for calling my API.

            services.AddHttpClient("MyApi", c =>
            {
#if DEBUG
                c.BaseAddress = new Uri("https://localhost:12345");
#else
                c.BaseAddress = new Uri("https://myApi.com");
#endif

But when I want to call the ActionResult by using an Ajax-call, he can't find the API.

    alert(apiUrl);

    $.ajax({
        url: apiUrl   '/MyApiProcesses/GetSomething',
        type: 'POST',

So I have written this variable in a js-file.

var apiUrl = 'https://localhost:12345';
//var apiUrl = 'https://myApi.com';

I want to know if it is possible to write it dynamically. If you declare it in the startup, you don't have to declare it twice?

If you need to use urls in ajax or httpclient, I usually do it this way, but it takes several steps to get a string from appsettings.

1. Create AppUrl section in appsettings.json

"AppUrl": {
    "DevUrl": "http//..",
    "ProductUrl": "http//..",
     .... another urls if needed
   
},

2.Create class for this section

 public class AppUrlSettings
  {
        public string DevUrl{ get; set; }
        public string ProdUrl{ get; set; }

        ....another urls
   }

3. configure settings in startup

var appUrlSection=Configuration.GetSection("AppUrl");

services.Configure<AppUrlSettings>(appUrlSection);

var urls = appUrlSection.Get<AppUrlSettings>();

services.AddHttpClient("MyApi", c =>
 {
#if DEBUG
                c.BaseAddress = new Uri(urls.DevUrl);
#else
                c.BaseAddress = new Uri(urls.ProdUrl;
#endif
});

4. now you can use them like this

public class MyController:Controller
    {
        private readonly IOptions<AppUrlSettings> _appUrls;

        public MyController (IOptions<AppUrlSettings> appUrls)
        {
            _appUrls = appUrls;
        }

        public  IActionResult MyAction()
        {
           var model= new Model
           {
            DevUrl=_appUrls.Value.DevUrl;
               ...
           }
        }
}

you can then use urls as hidden fields.

or you can get urls from model in javascript directly:

var devUrl = @Html.Raw(Json.Encode(@Model.DevUrl));
.....

Or if you need the urls in many places, it can make sense to create a special service that you can inject directly in the views you need

i don't know i catched the problem or not but I think apiUrl is not mandatory before "Controller/Action" for ajax Url propert. which means that is enough ..

    $.ajax({
            url:'/MyApiProcesses/GetSomething',
            type: 'POST',
