-# whmcs-api
-An WHMCS API C# Wrapper
+# WHMCS API C# Wrapper
+
+This is an library to comunicate with the WHMCS API<br/>
+Currently these functions are already implemented
+
+<ul>
+  <li>Add Client</li>
+  <li>Domain WhoIs</li>
+  <li>Get Client Details</li>
+  <li>Validate Login</li>
+</ul>
+
+The implemented functions are designed to be very easy to use
+The following code demonstrates to to implement the GetClientDetails on an ASP.net MVC app
+
+```
+using WHMCS-API;
+namespace YOUR_APP
+{
+    public class YOUR_CLASS
+    {
+        [HttpPost]
+        public ActionResult ClientDetails(int clientID)
+        {
+            string username = "WHMCS_USERNAME";
+            string password = "WHMCS_PASSWORD";
+            string accessKey = "WHNMCS_ACCESS_KEY";
+            string whmcsUrl = "WHMCS_USERFRONTEND_URL"; //ex: https://example.com/client
+            API api = new API(username, password, accessKey, whmcsUrl);
+            ViewBag.UserDetails = api.GetClientsDetails(clientID, Stats: true); //The model passed is of type GetClientsDetails
+            return View();
+        }
+    }
+}
+```
+
+You can still use this library to call non implemented functions by using the following code
+
+```
+using WHMCS-API.Call;
+using System.Collections.Specialized;
+using Newtonsoft.Json; //Not necessary but recommended as the call returns a JSON String
+
+namespace YOUR_APP
+{
+    public class YOUR_CLASS
+    {
+        //The function can be private or public and does not need to return anything or can even return an string or any other type
+        public YourModel yourFunction()
+        {
+            Call _call = new Call(WHMCS_API_USERNAME, WHMCS_API_PASSWORD, WHMCS_API_ACCESSKEY, WHMCS_USER_FRONTEND_URL);
+            NameValueCollection data = new NameValueCollection()
+            {
+                { "action", "ModuleChangePackage " },
+                { "accountid", "1" }
+            };
+
+            return JsonConvert.DeserializeObject<YourModel>(_call.MakeCall(data));
+        }
+    }
+}
+```
+
+You can also create custom functions of already implemented functions.<br />
+In this example i'm gonna show how to use the login function
+
+```
+using WHMCS-API;
+using WHMCS-API.Call;
+using System.Collections.Specialized;
+using Newtonsoft.Json; //Not necessary but recommended as the call returns a JSON String
+
+namespace YOUR_APP
+{
+    public class YOUR_CLASS
+    {
+        //The function can be private or public and does not need to return anything or can even return an string or any other type
+        public void _Login()
+        {
+            Call _call = new Call(WHMCS_API_USERNAME, WHMCS_API_PASSWORD, WHMCS_API_ACCESSKEY, WHMCS_USER_FRONTEND_URL);
+            NameValueCollection data = new NameValueCollection()
+            {
+                { "action", EnumUtil.GetString(APIEnums.Actions.ValidateLogin) },
+                { EnumUtil.GetString(APIEnums.ValidateLoginParams.Email), Email },
+                { EnumUtil.GetString(APIEnums.ValidateLoginParams.Password), Password }
+            };
+
+            ValidateLogin response =  JsonConvert.DeserializeObject<ValidateLogin>(_call.MakeCall(data));
+            Session["uid"] = response.UserID;
+            Session["upw"] = response.PasswordHash;
+        }
+    }
+}
