paypal_adaptive

This gem is a lightweight wrapper for the paypal adaptive payments API.

This is very much a work in progress! Use at your own risk or submit bug fixes :)

Before you need start, read the API manual https://www.x.com/docs/DOC-1531 and check out the forums on http://x.com It'll be invaluable for parameters and error messages. The gem keeps the request/response as hashes so you will have to read the manual to make the proper calls. I made a few test cases for further examples at http://github.com/tc/paypal_adaptive/tree/master/test/

HOWTO

Create paypal_adaptive.yml to your config folder: development: environment: "sandbox" username: "sandbox_username" password: "sandbox_password" signature: "sandbox_signature" application_id: "sandbox_app_id"

test:
  environment: "sandbox"
  username: "sandbox_username"
  password: "sandbox_password"
  signature: "sandbox_signature"
  application_id: "sandbox_app_id"

production:
  environment: "production"
  username: "my_production_username"
  password: "my_production_password"
  signature: "my_production_signature"
  application_id: "my_production_app_id"

Make the payment request:

pay_request = PaypalAdaptive::Request.new

data = {
"returnUrl" => "http://testserver.com/payments/completed_payment_request", 
"requestEnvelope" => {"errorLanguage" => "en_US"},
"currencyCode"=>"USD",  
"receiverList"=>{"receiver"=>[{"email"=>"[email protected]", "amount"=>"10.00"}]},
"cancelUrl"=>"http://testserver.com/payments/canceled_payment_request",
"actionType"=>"PAY",
"ipnNotificationUrl"=>"http://testserver.com/payments/ipn_notification"
}

pay_response = pay_request.pay(data)

if pay_response.success?
  redirect_to pp_response.approve_paypal_payment_url
else
  puts pay_response.errors.first['message']
  redirect_to failed_payment_url
end

Once the user goes to pp_response.approve_paypal_payment_url, they will be prompted to login to Paypal for payment.

Upon payment completion page, they will be redirected to http://testserver.com/payments/completed_payment_request.

They can also click cancel to go to http://testserver.com/payments/canceled_payment_request

The actual payment details will be sent to your server via "ipnNotificationUrl" You have to create a listener to receive POST messages from paypal. I added a Rails metal template in the templates folder which handles the callback.

Additionally, you can make calls to Paypal Adaptive's other APIs: payment_details, preapproval, preapproval_details, cancel_preapproval, convert_currency, refund

Input is just a Hash just like the pay method. Refer to the Paypal manual for more details.
