Uri.EscapeDataString or HttpUtility.UrlEncode does not work for my case

Question

I have an API in a project which I coded as following:

[Route("api/SearchCustomer/{customer}")]
[HttpGet]
public List<Customer> SearchCustomer(string customer)
{
    return customerRepo.GetSearchJoined(customer);
}

At first, I got an issue when I am calling this API from my front end, if customer contains dot or space(for example: https://www.somesite.com/walmart Inc.), I will get 404 error(cannot found this API). I find an easy way to solve this problem. Just add a "/" will solve this problem.( https://www.somesite.com/walmart Inc./ )

Now I need to call this API in another project at the back end. So I did something like this:

var urlParm = "https://www.somesite.com/api/SearchCustomer/" + name + "/";
response = client.GetAsync(urlParm).Result;
var dataObjects = response.IsSuccessStatusCode ? response.Content.ReadAsAsync<IList<Customer>>().Result : null;
return dataObjects;

Unfortunately, adding the "/" at back does not work. I am still getting 404 error. Then, I tried to use Uri.EscapeDataString or HttpUtility.UrlEncode to encode "name".( Does C# have an equivalent to JavaScript's encodeURIComponent()? )

name = Uri.EscapeDataString(name)
or name = HttpUtility.UrlEncode(name)
or name = HttpUtility.UrlPathEncode(name)
var urlParm = "https://www.somesite.com/api/SearchCustomer/" + name + "/";
or var urlParm = = "https://www.somesite.com/api/SearchCustomer/" + name
response = client.GetAsync(urlParm).Result;
var dataObjects = response.IsSuccessStatusCode ? response.Content.ReadAsAsync<IList<Customer>>().Result : null;
return dataObjects;

I have tried all the different matches of above code. All of them did not work. I am still getting the 404 error. Does anyone know what I am doing wrong here?

Sorry for the typo, I removed some sensitive information so I deleted the "api" by mistake. The route is not the problem. I have tested that the api call from the back end worksif name contains only letters or numbers but fails when name contains dot.

The problem is not relevant the customer parameter is encoded or not. You should specify the routing and apply the request correctly. Firstly fix the route;

[Route("api/SearchCustomer/{customer}")]

Then apply the request.
