Question

CreditCard Model
def charge_cents!(cents)
begin
gateway = ActiveMerchant::Billing::AuthorizeNetGateway.new($installation[:authorize])
response = nil
Timeout::timeout(120.seconds) {
response = gateway.purchase(cents, self.to_am_creditcard, {
:order_id => self.customer.contract_number[1..-1],
:cust_id => self.customer.contract_number[1..-1]
}.merge(self.am_billing_address_hash))
}
return response
rescue
return response = nil
end
end
to_am_creditcard
def to_am_creditcard
ActiveMerchant::Billing::CreditCard.new({
:number => self.number,
:month => self.month,
:year => self.year,
:first_name => self.first_name,
:last_name => self.last_name,
})
end
am_billing_address_hash
def am_billing_address_hash
{:billing_address => self.to_hash }
end
Now, Take last credit card
1.9.3p484 :003 > #card = CreditCard.last
=> #<CreditCard id: 17263, crypted_number: "uXHr8wFYPvlaLWkB7hMltzex60ZtINOMH7EDB+/uSZU=\n", last_4: "4242", first_name: "test3", last_name: "test4", phone: "1234567890", customer_id: 66837, month: 7, year: 2017, address_id: 230222, created_at: "2014-07-11 03:36:21", updated_at: "2014-07-11 03:36:21">
and Now, use charge_cents method
1.9.3p484 :006 > response = #card.charge_cents!(amount * 100.0)
=> #<ActiveMerchant::Billing::Response:0xbac6ce0 #params={"response_code"=>2, "response_reason_code"=>"2", "response_reason_text"=>"This transaction has been declined.", "avs_result_code"=>"U", "transaction_id"=>"6328764577", "card_code"=>"", "authorization_code"=>"", "cardholder_authentication_code"=>"", "action"=>"AUTH_CAPTURE"}, #message="This transaction has been declined", #success=false, #test=false, #authorization="6328764577", #fraud_review=false, #avs_result={"code"=>"U", "message"=>"Address information unavailable.", "street_match"=>nil, "postal_match"=>nil}, #cvv_result={"code"=>nil, "message"=>nil}>

I don't know why I am getting this error, It's working on test mode but when I remove a test mode then getting this error.
or, If any other way to integrate auth.net with ruby on rails 3.2 then please help for this with code.
Update
I am passing this data:
CC Number : 4242424242424242
ExpireDate : 11/2015
Please Help Me.
Thanks, In Advance.

Answer 1

First, when you specify Test Mode, the gateway only checks if the API Login and Transaction Key are correct and returns success if valid. This is true for both the sandbox or production. You should never use test mode in the sandbox.
Try using 4111111111111111 in the sandbox with test mode=false to test a transaction.
