Mercadolibre gem implements MELI API (Official API available to interact with Mercadolibre) and MPAGO API (official API for Mercadopago).
It implements all the methods of the official API and it makes it very easy to interact with.
You need to create an application in http://applications.mercadolibre.com in order to get app key and app secret.
Rest Client is used to perform all API calls.
gem install mercadolibre
MELI uses OAuth protocol for authentication, so you first need to get an access token.
In order to do that you first need to instance the API:
api = Mercadolibre::Api.new({
app_key: 'YOUR_APP_KEY',
app_secret: 'YOUR_APP_SECRET',
callback_url: 'YOUR_CALLBACK_URL',
site: 'YOUR_SITE_COUNTRY'
})
Site country is the site id for the country you are using (eg. Argentina's site id is MLA).
In case you already have an access token, it could be passed directly in the constructor hash or it can be assigned through property 'access_token'.
To get a url of mercadolibre authentication page you can call authenticate_url method:
# it returns the authentication page you should send user to
api.authenticate_url
After authentication, you'll be redirected to callback url with an auth code (code variable from return url). With this code, you'll get access token (also refresh token in case you need it).
# auth_data (access_token, refresh_token, expired_at)
auth_data = api.authenticate(your_auth_code)
As soon as you are authenticated and you have a valid access token, you are all set for using the API.
