Epsilon Link Payment

EpsilosLinkPaymentGateway is available in all link payments. For example, GMO Payment After Delivery.

If you don't need to send paramaters of delivery information details(e.g. consignee_postal, consignee_name, orderer_postal, and orderer_name), you set delivery_info_required to false.

Default value of delivery_info_required is true, therefore you must set delivery information details to purchase_detail When you don't set delivery_info_required.

ActiveMerchant::Billing::EpsilonLinkPaymentGateway.contract_code = 'YOUR_CONTRACT_CODE'

gateway = ActiveMerchant::Billing::EpsilonLinkPaymentGateway.new

amount = 10000

purchase_detail = {
  user_id:           'YOUR_APP_USER_IDENTIFIER',
  user_name:         '山田 太郎',
  user_email:        '[email protected]',
  user_tel:          '0312345678',
  item_code:         'ITEM001',
  item_name:         'Greate Product',
  order_number:      'UNIQUE ORDER NUMBER',
  st_code:           'SETTLEMENT_CODE',
  consignee_postal:  '1500002',
  consignee_name:    '山田 太郎',
  consignee_address: '東京都渋谷区1-1-1',
  consignee_tel:     '0312345678',
  orderer_postal:    '1500002',
  orderer_name:      '山田 太郎',
  orderer_address:   '東京都渋谷区1-1-1',
  orderer_tel:       '0312345678',
  memo1:             'memo1',
  memo2:             'memo2',
}

delivery_info_required = true

response = gateway.purchase(amount, purchase_detail, delivery_info_required)

if response.success?
  puts "Successfully send order data"
  puts "Redirect url is #{response.params['redirect']}"
else
  raise StandardError, response.message
end

Epsilon Link Payment Void Transaction

gateway.void('order_number')

Error handling

If epsilon server returns status excepted 200, #purchase method raise ActiveMerchant::ResponseError.

When your request parameters are wrong(e.g. contract_code), the method returns failure response.

#success? returns false
#params has error detail

response = gateway.purchase(10000, creadit_card, invalid_detail)

response.success? # => false
response.params   # => Hash included error detail
