This is a Ruby client for all the services offered by MercadoPago.
You should read the MercadoPago API documentation before you use this gem. This gem works with hashes and only deals with requests/responses. That's why you will need an understanding of their services.
You can read the documentation of the MercadoPago API here:
- Portuguese: https://developers.mercadopago.com/integracao-checkout
- Spanish: https://developers.mercadopago.com/integracion-checkout
mercadopago 2.0.0 needs Ruby 1.9. Version 1.0.2 runs fine with Ruby 1.8.
To install the last version of the gem:
gem install mercadopago
If you are using bundler, add this to your Gemfile:
gem 'mercadopago'
To use this gem, you will need the client_id and client_secret for a MercadoPago account.
In any case, this gem will not store this information. In order to find out your MercadoPago credentials, you can go here:
- Brasil: https://www.mercadopago.com/mlb/ferramentas/aplicacoes
- Argentina: https://www.mercadopago.com/mla/herramientas/aplicaciones
The first thing to do is create a client. The client will authenticate with MercadoPago and will allow you to interact with the MercadoPago API.
# Use your credentials
client_id = '1234'
client_secret = 'abcdefghijklmnopqrstuvwxyz'
mp_client = MercadoPago::Client.new(client_id, client_secret)
If any error ocurred while authenticating with MercadoPago, an AccessError will be raised. If nothing goes wrong, no errors are raised and you are ready to use the API.
Your request will need a hash to explain what the payment is for. For example:
data = {
external_reference: "OPERATION-ID-1234",
items: [
{
id: "Código 123",
title: "Example T-Shirt",
description: "Red XL T-Shirt",
quantity: 1,
unit_price: 10.50,
currency_id: "BRL",
picture_url: "http://www.site.com/image/123.png"
}
],
payer: {
name: "John",
surname: "Mikel",
email: "buyer@email.com"
},
back_urls: {
pending: "https://www.site.com/pending",
success: "http://www.site.com/success",
failure: "http://www.site.com/failure"
}
}
payment = mp_client.create_preference(data)
If everything worked out alright, you will get a response like this:
{
"payment_methods" => {},
"init_point" => "https://www.mercadopago.com/mlb/checkout/pay?pref_id=abcdefgh-9999-9999-ab99-999999999999",
"collector_id" => 123456789,
"back_urls" => {
"pending"=> "https://www.site.com/pending",
"success"=> "http://www.site.com/success",
"failure"=> "http://www.site.com/failure"
},
"sponsor_id" => nil,
"expiration_date_from" => nil,
"additional_info" => "",
"marketplace_fee" => 0,
"date_created" => "2012-05-07T20:07:52.293-04:00",
"subscription_plan_id" => nil,
"id" => "abcdefgh-9999-9999-ab99-999999999999",
"expiration_date_to" => nil,
"expires" => false,
"external_reference" => "OPERATION-ID-1234",
"payer" => {
"email" => "buyer@email.com",
"name" => "John",
"surname" => "Mikel"
},
"items" => [
{
"id" => "Código 123",
"currency_id" => "BRL",
"title" => "Example T-Shirt",
"description" => "Red XL T-Shirt",
"picture_url" => "http://www.site.com.br/image/123.png",
"quantity" => 1,
"unit_price" => 10.50
}
],
"client_id" => "963",
"marketplace" => "NONE"
}
To check the payment status you will need the payment ID. Only then you can call the MercadoPago IPN.
# Use the payment ID received on the IPN.
payment_id = '987654321'
notification = mp_client.notification(payment_id)
You will get a response like this one:
{
"collection" => {
"id" => 987654321,
"site_id" => "MLB",
"operation_type" => "regular_payment",
"order_id" => nil,
"external_reference" => "OPERATION-ID-1234",
"status" => "approved",
"status_detail" => "approved",
"payment_type" => "credit_card",
"date_created" => "2012-05-05T14:22:43Z",

"date_approved" => "2012-05-05T14:22:43Z",
"money_release_date" => "2012-05-19T14:22:43Z",
"currency_id" => "BRL",
"transaction_amount" => 10.50,
"shipping_cost" => 0,
"total_paid_amount" => 10.50,
"finance_charge" => 0,
"net_received_amount" => 0,
"marketplace" => "NONE",
"marketplace_fee" => nil,
"reason" => "Example T-Shirt",
"payer" => {
"id" => 543219876,
"first_name" => "John",
"last_name" => "Mikel",
"nickname" => "JOHNMIKEL",
"phone" => {
"area_code" => nil,
"number" => "551122334455",
"extension" => nil
},
"email" => "buyer@email.com",
"identification" => {
"type" => nil,
"number" => nil
}
},
"collector" => {
"id" => 123456789,
"first_name" => "Bill",
"last_name" => "Receiver",
"phone" => {
"area_code" => nil,
"number" => "1122334455",
"extension" => nil
},
"email" => "receiver@email.com",
"nickname" => "BILLRECEIVER"
}
}
}
To search over the collections (payments that you may be processing) you need to create a hash with the params that you want to search for an send it to the search method of the client instance.
# Create a hash to search for
search_hash = { external_reference: 'OPERATION-ID-1234' }
search = mp_client.search(search_hash)
You will get a response like this one:
{
"results"=>[
{
"collection" => {
"marketplace" =>"NONE",
"sponsor_id" =>nil,
"status" => "approved",
"status_detail" => "approved",
"payer" => {
"id" => 543219876,
"first_name" => "John",
"last_name" => "Mikel",
"nickname" => "JOHNMIKEL",
"phone" => {
"area_code" => nil,
"number" => "551122334455",
"extension" => nil
},
"email" => "buyer@email.com",
"identification" => {
"type" => nil,
"number" => nil
}
},
"currency_id" => "BRL",
"external_reference" => "OPERATION-ID-1234",
"transaction_amount" => 10.50,
"shipping_cost" => 0,
"total_paid_amount" => 10.50,
"id" => 987654321,
"status_code" => nil,
"reason" => "Example T-Shirt",
"collector_id" => 99678614,
"date_created" => "2012-05-05T14:22:43Z",
"last_modified" => "2012-05-05T14:35:13Z",
"date_approved" => "2012-05-05T14:22:43Z",
"money_release_date" => "2012-05-19T14:22:43Z",
"released" => "yes",
"operation_type" => "regular_payment",
"payment_type" => "credit_card",
"site_id" => "MLB"
}
}
],
"paging" => {
"total" => 1,
"limit" => 30,
"offset" => 0
}
}
And the parameters thay could be used in the search hash are:
