run

gem install netaxept

or include in your Gemfile:

gem 'netaxept'

First step is to tell Netaxept your credentials and the desired mode:

Netaxept::Service.authenticate <merchant id>, <token>
Netaxept::Service.environment =  :test|:production

To interact with Netaxept you need to create an instance of Netaxept::Service:

service = Netaxept::Service.new

Every request returns a Netaxept::Response object, which has a success? method. In case of an error you can call errors, which gives you a list of Netaxept::ErrorMessages (each with a message, code, source and text).

The following applies for the Nets hosted service type where the user is redirect to the Netaxept site to enter her payment details (see the Netaxept docs for details).

service.register <amount in cents>, <order number>, <options>

Required options are CurrencyCode (3 letter ISO code) and redirectUrl.

On success the response object gives you a transaction_id. You pass that to Netaxept::Service.terminal_url(<transaction id>) to get the URL for redirecting the user.

For details on the options see http://www.betalingsterminal.no/Netthandel-forside/Teknisk-veiledning/API/Register/

After the user has authorized the payment on the Netaxept site he is redirected to the redirectUrl you provided. Netaxept adds a resonseCode and transactionId parameter to the URL. To finalize the payment you call sale on the service.

service.sale <transaction id>, <amount in cents>

The response is a Responses::SaleResponse which only has the success? and errors methods mentioned under General.

Congratulations, you have processed a payment.

To run the tests:

$ bundle
$ rake MERCHANT_ID=<your merchant id> NETAXEPT_TOKEN=<your token>
