Hello, I would like to make an integration to Mercadolibre (ebay mexico). At the moment I want to do something like update some basic data but I do not get it to work and I want to know if the code I have at the moment could work ...

http://developers.mercadolibre.com/products-sync-listings/#Update-your-item

I try to integrate with third party apis using get / posturl tasks. I recommend it, I'm not sure if it is possible.

Header_map = map ();

Header_map.put ("Content-Type", "application / json");

Header_map.put ("Accept", "application / json");

Params_map = map ();

Params_map.put ("title", "Your new title");

Params_map.put ("price", 1000);

Mercadolibre_resp = postUrl (" https://api.mercadolibre.com/items/ITEM_ID?access_token=YOUR_ACCESS_TOKEN", params_map, header_map);

Any ideas or suggestions? Thank you!
