PayPal REST API Ruby SDK

The PayPal REST SDK provides Ruby APIs to create, process and manage payment.

PayPal Checkout v2

Please note that if you are integrating with PayPal Checkout, this SDK and corresponding API v1/payments are in the process of being deprecated.

We recommend that you integrate with API v2/checkout/orders and v2/payments. Please refer to the Checkout Ruby SDK to continue with the integration.

2.0 Release Candidate!

We're releasing a brand new version of our SDK! 2.0 is currently at release candidate status, and represents a full refactor, with the goal of making all of our APIs extremely easy to use. 2.0 includes all of the existing APIs (except payouts), and includes the new Orders API (disputes and Marketplace coming soon). Check out the FAQ and migration guide, and let us know if you have any suggestions or issues!

Prerequisites

• Ruby 2.0.0 or above
• Bundler

Installation

Add this line to your application's Gemfile:

gem 'paypal-sdk-rest'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paypal-sdk-rest

Configuration

For Rails application:

rails g paypal:sdk:install

For other ruby application, create a configuration file(config/paypal.yml):

development: &default
  mode: sandbox
  client_id: EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM
  client_secret: EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM
  # # with Proxy
  # http_proxy: http://proxy-ipaddress:3129/
  # # with CA File
  # ssl_options:
  #   ca_file: config/cacert.pem
  # # Override Endpoint
  # rest_endpoint: https://api.sandbox.paypal.com
test:
  <<: *default
production:
  mode: live
  client_id: CLIENT_ID
  client_secret: CLIENT_SECRET

Load Configurations from specified file:

PayPal::SDK::Core::Config.load('spec/config/paypal.yml',  ENV['RACK_ENV'] || 'development')

Without configuration file:

PayPal::SDK.configure(
  :mode => "sandbox", # "sandbox" or "live"
  :client_id => "EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM",
  :client_secret => "EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM",
  :ssl_options => { } )

Logger configuration:

PayPal::SDK.logger = Logger.new(STDERR)

# change log level to INFO
PayPal::SDK.logger.level = Logger::INFO

NOTE: At DEBUG level, all requests/responses are logged except when mode is set to live. In order to disable request/response printing, set the log level to INFO or less verbose ones.

OpenIDConnect Samples

require 'paypal-sdk-rest'

# Update client_id, client_secret and redirect_uri
PayPal::SDK.configure({
  :openid_client_id     => "client_id",
  :openid_client_secret => "client_secret",
  :openid_redirect_uri  => "http://google.com"
})
include PayPal::SDK::OpenIDConnect

# Generate URL to Get Authorize code
puts Tokeninfo.authorize_url( :scope => "openid profile" )

# Create tokeninfo by using AuthorizeCode from redirect_uri
tokeninfo = Tokeninfo.create("Replace with Authorize Code received on redirect_uri")
puts tokeninfo.to_hash

# Refresh tokeninfo object
tokeninfo = tokeninfo.refresh
puts tokeninfo.to_hash

# Create tokeninfo by using refresh token
tokeninfo = Tokeninfo.refresh("Replace with refresh_token")
puts tokeninfo.to_hash

# Get Userinfo
userinfo = tokeninfo.userinfo
puts userinfo.to_hash

# Get logout url
put tokeninfo.logout_url

Create Payment

require 'paypal-sdk-rest'
include PayPal::SDK::REST

PayPal::SDK::REST.set_config(
  :mode => "sandbox", # "sandbox" or "live"
  :client_id => "EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM",
  :client_secret => "EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM")

# Build Payment object
@payment = Payment.new({
  :intent =>  "sale",
  :payer =>  {
    :payment_method =>  "paypal" },
  :redirect_urls => {
    :return_url => "http://localhost:3000/payment/execute",
    :cancel_url => "http://localhost:3000/" },
  :transactions =>  [{
    :item_list => {
      :items => [{
        :name => "item",
        :sku => "item",
        :price => "5",
        :currency => "USD",
        :quantity => 1 }]},
    :amount =>  {
      :total =>  "5",
      :currency =>  "USD" },
    :description =>  "This is the payment transaction description." }]})

if @payment.create
  @payment.id     # Payment Id
else
  @payment.error  # Error Hash
end

Get Payment details

# Fetch Payment
payment = Payment.find("PAY-57363176S1057143SKE2HO3A")

# Get List of Payments
payment_history = Payment.all( :count => 10 )
payment_history.payments

Execute Payment

payment = Payment.find("PAY-57363176S1057143SKE2HO3A")

if payment.execute( :payer_id => "DUFRQ8GWYMJXC" )
  # Success Message
  # Note that you'll need to `Payment.find` the payment again to access user info like shipping address
else
  payment.error # Error Hash
end

# Create tokeninfo by using Authorize Code from redirect_uri
tokeninfo = Tokeninfo.create("Replace with Authorize Code received on redirect_uri")

# Refresh tokeninfo object
tokeninfo.refresh

# Create tokeninfo by using refresh token
tokeninfo = Tokeninfo.refresh("Replace with refresh_token")

# Get Userinfo
userinfo = tokeninfo.userinfo

# Get Userinfo by using access token
userinfo = Userinfo.get("Replace with access_token")

# Get logout url
logout_url = tokeninfo.logout_url

Payouts

To make Payouts, you should enable this option in your account at http://developer.paypal.com.

@payout = Payout.new(
  {
    :sender_batch_header => {
      :sender_batch_id => SecureRandom.hex(8),
      :email_subject => 'You have a Payout!',
    },
    :items => [
      {
        :recipient_type => 'EMAIL',
        :amount => {

          :currency => 'USD'
        },
        :note => 'Thanks for your patronage!',
        :receiver => 'shirt-supplier-one@mail.com',
        :sender_item_id => "2014031400023",
      }
    ]
  }
)

begin
  @payout_batch = @payout.create
  logger.info "Created Payout with [#{@payout_batch.batch_header.payout_batch_id}]"
