Permissions SDK

The PayPal Permission SDK provides Ruby APIs for developers to request and obtain permissions from merchants and consumers, to execute APIs on behalf of them. The permissions include variety of operations from processing payments to accessing account transaction history.

Support

Please contact PayPal Technical Support for any live or account issues.

Installation

Add this line to your application's Gemfile:

gem 'paypal-sdk-permissions'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paypal-sdk-permissions

Configuration

For Rails application:

rails g paypal:sdk:install

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

development: &default
  username: jb-us-seller_api1.paypal.com
  password: WX4WTU3S8MY44S7F
  signature: AFcWxV21C7fd0v3bYYYRCpSSRl31A7yDhhsPUU2XhtMoZXsWHFxu-RWy
  app_id: APP-80W284485P519543T
  http_timeout: 30
  mode: sandbox
  # # with certificate
  # cert_path: "config/cert_key.pem"
  # # with token authentication
  # token: ESTy2hio5WJQo1iixkH29I53RJxaS0Gvno1A6.YQXZgktxbY4I2Tdg
  # token_secret: ZKPhUYuwJwYsfWdzorozWO2U9pI
  # # with Proxy
  # http_proxy: http://proxy-ipaddress:3129/
  # # with device ip address
  # device_ipaddress: "127.0.0.1"
test:
  <<: *default
production:
  <<: *default
  mode: live

Load Configurations from specified file:

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

Example

Request permission:

require 'paypal-sdk-permissions'

PayPal::SDK.configure({
  :mode      => "sandbox",  # Set "live" for production
  :app_id    => "APP-80W284485P519543T",
  :username  => "jb-us-seller_api1.paypal.com",
  :password  => "WX4WTU3S8MY44S7F",
  :signature => "AFcWxV21C7fd0v3bYYYRCpSSRl31A7yDhhsPUU2XhtMoZXsWHFxu-RWy" })

@api = PayPal::SDK::Permissions::API.new

# Build request object
@request_permissions = @api.build_request_permissions({
  :scope => ["ACCESS_BASIC_PERSONAL_DATA","ACCESS_ADVANCED_PERSONAL_DATA"],
  :callback => "http://localhost:3000/samples/permissions/get_access_token" })

# Make API call & get response
@response = @api.request_permissions(@request_permissions)

# Access Response
if @response.success?
  @response.token
  # Redirect url to grant permissions
  redirect_to @api.grant_permission_url(@response)
  # When the user then logs into PayPal and grants the requested permissions, the user will get redirected to the
  # callback url defined when building the permissions-request.
else
  @response.error
end

# In the controller handling the callback:
# http://localhost:3000/samples/permissions/get_access_token

class PermissionsController < ApplicationController
  include PayPal::SDK::Permissions

  def get_access_token
    api = PayPal::SDK::Permissions::API.new

    # Build request to exchange tokens
    request_access_token = api.build_get_access_token(
      # As an additional security measure, you should verify that the below "params['request_token']" is the
      # same token as the "@response.token" above for the current user. For instance, you could store the
      # "@response.token" in the user's session before the redirect and verify in this method.
      :token    => params['request_token'],
      :verifier => params['verification_code']
    )

    # Make API call & get response
    access_token_response = api.get_access_token(request_access_token)

    # Access Token Response
    if access_token_response.success?
      token        = access_token_response.token
      token_secret = access_token_response.token_secret
      # Now you have a token and token_secret you can use to make requests.
    else
      @error = access_token_response.error
      # Handle the error here
    end
  end
end

Make API call with token and token_secret:

@api = PayPal::SDK::Permissions::API.new({
   :token => "3rMSi3kCmK1Q3.BKxkH29I53R0TRLrSuCO..l8AMOAFM6cQhPTTrfQ",
   :token_secret => "RuE1j8RNRlSuL5T-PSSpVWLvOlI" })

@response = @api.get_basic_personal_data({
  :attributeList => {
    :attribute => [ "http://axschema.org/namePerson/first" ] } })
You can’t perform that action at this time.
