Hi @Mohammad Qasim ,
You can refer to the following code to login sharepoint 2019

private void SignInUser()  
{  
    var mem = (MyMembershipProvider) Utils.BaseMembershipProvider();  
    var role = (MyRoleProvider) Utils.BaseRoleProvider();  
    if (!mem.ValidateUser(_userName, _password))  
    {  
        return;  
    }  
  
    SecurityToken token = SPSecurityContext.SecurityTokenForFormsAuthentication  
                                     (new Uri(SPContext.Current.Web.Url),  
                                     mem.Name,  
                                     role.Name,  
                                     _userName,  
                                     _password,  
                                     _remember);  
    SPFederationAuthenticationModule.Current.SetPrincipalAndWriteSessionToken(token);  
  
    Response.Redirect(Request.QueryString["Source"]);  
}

did I understand correctly that you need to call some custom API endpoint http://172.16.10.82/api/v1/auth from codebehind (C# code which runs on server side) of login page which is used in Sharepoint FBA site? If yes you need to add event handler (e.g. button click) which will cause postback to the server. In handler of this event you need to write code which will send HTTP request to API using basic authentication - like you test it in Postman. Here you may find example how to do that (search for "C# HttpClient Basic authentication"): https://zetcode.com/csharp/httpclient.
