C# Get all records from Web API where pagination is implemented

My requirement is accessing a third party Web API, which has total of 120 records (just an example - it can be more). The Api has pagination implemented which returns default 50 records based on page number. By passing {Page} in parameters, we can get other 50 records for that page number:

Example :

https://www.thirdpartapi.com/users?Page=1

https://www.thirdpartapi.com/users?Page=2

This is the response from API -

{
 "total" : 120,
 "users" : [
     {
        "id" : "abc123",
        "firstName" : "First1",
        "lastName" : "Last1"
     },
     {
        "id" : "abc124",
        "firstName" : "First2",
        "lastName" : "Last2"
     },
     ...... 50 users
  ]
}

I want to get all 120 users records from the Web API.

this is my Response model:

public class ApiResponse
{
     public int total { get; set; }
     public List<Users> users { get; set; }
     public ApiResponse()
     {
         users = new List<Users>();
     }
}

public class Users
{
     public string id { get; set; }
     public string firstName { get; set; }
     public string lastName{ get; set; } 
}

I am making a recursive call to the WebAPI to get all the 120 records:

List<Users> = (List<Users>)CallApi();

private List<Users> CallApi(int? pageNumber = 1)
{        
    var response = webmanager.RestApi("https://www.thirdpartapi.com/users?Page={pageNumber}");
    
    ApiResponse data = (ApiResponse)JsonConvert.DeserializeObject(response, typeOf(ApiResponse));

    if(data.users.Count > 0)
    { 
        data.users.AddRange((IEnumberable<Users>)CallApi(pageNumber + 1));
        return data.users;
    }
    else
        return data.users;
 }
 

I am able to get all the Users (120). But is this an optimal way to call an API? Please suggest a better solution.
