Ruby on Rails implementation for the european 1&1 iPayment gateway for credit card processing.
Technical documentation from iPayment: http://www.1und1.info/downloads/ipayment_Technik-Handbuch_2008-08.pdf (German)
This plugin provides a simple way to implement credit card processing by providing wrappers and helpers around the 1&1 iPayment SOAP API. As the credit card data doesn't touch your application's servers, no PCI certification is needed.
See the example/ directory for some example code.
How it works
- form_for_ipayment_auth creates a session and stores transaction data into it (amount, currency, etc.).
- The HTML form POSTs the user entered credit card data SSL secured directly to the iPayment servers.
- The iPayment servers will process the transaction and request the callback_url provided to form_for_ipayment_auth passing the result to it. At this point your application should handle the transaction, e.g. booking the amount to the user account if it is successful.
- iPayment will redirect the user to success_url if the transactions succeeds or to error_url if it doesn't.
- All this happens transparently to the user – except for a short change in the address field of the browser, he stays on your site.
How to get it work
- Get iPayment credentials and put them into the config file. The file goes into RAILS_ROOT/config/ipayment.yml (or use a test account, see ipayment_Technik-Handbuch_2008-08.pdf page 10).
- Implement a controller to handle callback, success and error (see controller.rb example).
- Add a view using form_for_ipayment_auth passing it an Ipayment::Payment with payment data (see controller.rb and new.html.erb).
Note on Patches/Pull Requests
- Fork the project.
- Make your feature addition or bug fix.
- Add specs for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
