Rails Integration

Payme isn’t dependent of rails. It integrates well with it though (both 2.3 and 3).
Here’s how I’ve integrated it in my case.

Create a new initializer config/initializers/payme.rb With the following :

Payme::Config.set_config('config/payme.yml', Rails.env) (Rails >= 2.3.6 syntax)

It’ll load your payme’s config file when the application starts (you must restart your server every time you change that configuration).

Create your config file config/payme.yml

test:
  merchant_id: '014213245611111'
  bin_path: <%= Rails.root %>/lib/payme
  pathfile: <%= Rails.root %>/lib/payme/param/pathfile
development:
  merchant_id: '014213245611111'
  bin_path: <%= Rails.root %>/lib/payme
  pathfile: <%= Rails.root %>/lib/payme/param/pathfile
production:
  merchant_id: 'provided_by_your_bank'
  bin_path: <%= Rails.root %>/lib/payme
  pathfile: <%= Rails.root %>/lib/payme/param/pathfile

Then create a new controller which will handle your payments. Mine looks like this :

class PaymentsController < ApplicationController
  #
  # Display the payment page
  #
  def new
    @amount = 1500 # Replace this with the real amount
    @request = Payme::Request.new(@amount).launch
  end

  #
  # After the payment, the user is redirected here
  #
  def create
    @response = Payme::Response.new(params[:DATA]).launch
  end
end

And you have the request and response, which you can use in your views to display whatever you want !
