This is the official .NET SDK for MercadoLibre's Platform.

You can download the latest build at: http://github.com/mercadolibre/net-sdk/downloads

And that's it!

The first thing to do is to instance a Meli class. You'll need to give a clientId and a clientSecret. You can obtain both after creating your own application. For more information on this please read: creating an application

Meli m = new Meli(1234, "a secret");

With this instance you can start working on MercadoLibre's APIs.

There are some design considerations worth to mention.

1. This SDK is just a thin layer on top of an http client to handle all the OAuth WebServer flow for you.
2. There is no JSON parsing. This is left to you. But this SDK uses json.net library for internal usage.

This is a 2 step process.

First get the link to redirect the user. This is very easy! Just:

string redirectUrl = m.GetAuthUrl(Meli.AuthUrls.MLB,"http://somecallbackurl"); //Don't forget to set the autentication URL of your country

This will give you the url to redirect the user. You need to specify a callback url which will be the one that the user will redirected after a successfull authrization process.

Once the user is redirected to your callback url, you'll receive in the query string, a parameter named code. You'll need this for the second part of the process.

m.Authorize("the received code", "http://somecallbackurl");

This will get an accessToken and a refreshToken (is case your application has the offline_access) for your application and your user.

At this stage your are ready to make call to the API on behalf of the user.

var p = new Parameter ();
p.Name = "access_token";
p.Value = m.AccessToken;

var ps = new List<Parameter> ();
ps.Add (p);
IRestResponse response = m.Get ("/users/me", ps);

var p = new Parameter ();
p.Name = "access_token";
p.Value = m.AccessToken;

var ps = new List<Parameter> ();
ps.Add (p);
IRestResponse r = m.Post ("/items", ps, new {foo="bar"});

var p = new Parameter ();
p.Name = "access_token";
p.Value = m.AccessToken;

var ps = new List<Parameter> ();
ps.Add (p);
IRestResponse r = m.Put ("/items/123", ps, new {foo="bar"});

var p = new Parameter ();
p.Name = "access_token";
p.Value = m.AccessToken;

var ps = new List<Parameter> ();
ps.Add (p);
IRestResponse r = m.Delete ("/items/123", ps);

No. Actually most GET requests don't need an access_token and it is easier to avoid them and also it is better in terms of caching. But this decision is left to you. You should decide when it is necessary to include it or not.

You can contact us if you have questions using the standard communication channels described in the developer's site

That is great! Just fork the project in github. Create a topic branch, write some code, and add some tests for your new code.

To run the tests run make test.

You'll need nodejs in order to run the tests. We use it to mock the API.

Thanks for helping!
