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 APIsmp.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):

JSONObjectresult = mp.get ("/sites", null, false);
out.print(result);
