MercadoPago Gem

Developed by Kauplus. Maintained by OmbuLabs.

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://www.mercadopago.com.br/developers/pt/
Spanish: https://www.mercadopago.com.ar/developers/es/
English: https://www.mercadopago.com/developers/

Installation

mercadopago 2.3.0 needs Ruby >= 2.0.0. Ruby 1.9.3 does not support TLS v1.2, which is required by MercadoPago starting June 30th 2018.

To install the last version of the gem:

gem install mercadopago

If you are using bundler, add this to your Gemfile:

gem 'mercadopago'

Access Credentials

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

How to use

Client creation

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 occurred 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.

Payment Creation

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",

Payment Status Verification

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",

      "email"     => "receiver@email.com",
      "nickname"  => "BILLRECEIVER"
    }
  }
}

Search in the collections

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",

          },

        "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,

Auto Pagination

It is also possible to inform if whether or not the result should be automatically paginated to return all payments. By default MercadoPago return only 30 payments on each request and if you setting up auto_paginate to true, will be made as many requests as needed to return all payments that matches with your search.

# Create a hash to search for
search_hash = { external_reference: 'OPERATION-ID-1234' }

# setup the auto_paginate to true
mp_client.auto_paginate = true

# do the desired search
search = mp_client.search(search_hash)

Sandbox mode

The sandbox mode can be enabled/disabled as follows:

mp_client.sandbox_mode(true)  # Enables sandbox
mp_client.sandbox_mode(false) # Disables sandbox

Recurring Payment Creation

Your request will need a hash to explain what the recurring payment is for. For example:

data = {
  payer_email:        "xxx@test.com",
  back_url:           "http://www.site.com/return",
  reason:             "Monthly Magazine",
  external_reference: "OPERATION-ID-1234",
  auto_recurring: {
    frequency:          1,
    frequency_type:     "months",
    transaction_amount: 12.55,
    currency_id:        "BRL"
  }
}

If everything worked out alright, you will get a response like this:

Errors

Errors will also be hashes with status code, message and error key.

For example, if you request payment method status for an invalid operation, you will see something like this:

{
 "message"  => "Resource not found",
 "error"    => "not_found",
 "status"   => 404,
 "cause"    => []
}

Tests

This gem has tests for a few methods. To check if it is working properly, just run:

rake test
