A lightweight ruby wrapper for PayPal NVP APIs. To install type the following at the command line:
$ gem install ruby-paypal
It‘s critical that you understand how PayPal works and how the PayPal NVP API works. You should be relatively well-versed in the NVP API Developer Guide and Reference (www.paypal.com/en_US/ebook/PP_NVPAPI_DeveloperGuide/index.html). You should also visit and register yourself with the PayPal Developer Network and get a Sandbox account with in the PayPal Development Central (developer.paypal.com/).
Note that this library only supports the API signature method of securing the API credentials.
To use credit card payment through PayPal, you need to use the DoDirectPayment APIs:
username = <PayPal API username>
password = <PayPal API password>
signature = <PayPal API signature>
ipaddress = '192.168.1.1' # can be any IP address
amount = '100.00' # amount paid
card_type = 'VISA' # can be Visa, Mastercard, Amex etc
card_no = '4512345678901234' # credit card number
exp_date = '022010' # expiry date of the credit card
first_name = 'Sau Sheong'
last_name = 'Chang'
paypal = Paypal.new(username, password, signature) # uses the PayPal sandbox
response = paypal.do_direct_payment_sale(ipaddress, amount, card_type,
card_no, exp_date, first_name, last_name)
if response.ack == 'Success' then
# do your thing
end
The above code is for a final sale only.
Note that the credit card number is checked against a modulo-10 algorithm (Luhn check) as well as a simple credit card type check. For more information please refer to en.wikipedia.org/wiki/Luhn_algorithm and en.wikipedia.org/wiki/Credit_card_number
To use the customer‘s PayPal account for payment, you will need to use the ExpressCheckout APIs:
