Generic methods

You can access any other resource from the MercadoPago API using the generic methods:

// Get a resource, with optional URL params. Also you can disable authentication for public APIs
mp.get ("/resource/uri", [params], [authenticate=true]);

// Create a resource with "data" and optional URL params.
mp.post ("/resource/uri", data, [params]);

// Update a resource with "data" and optional URL params.
mp.put ("/resource/uri", data, [params]);

// Delete a resource with optional URL params.
mp.delete ("/resource/uri", [params]);

For example, if you want to get the Sites list (no params and no authentication):

JSONObject result = mp.get ("/sites", null, false);

out.print(result);
