Usage

Request

The example below uses an OrdersController#create action to create an order from params[:order] and sets up the OmniKassa request.

class OrdersController
  def create
    # Save order in database
    @order = Order.create(params[:order])

    # OmniKassa preparation
    omnikassa                   = OmniKassa::Request.new
    omnikassa.order_id          = @order.id
    omnikassa.amount            = @order.amount
    omnikassa.normal_return_url = payments_url

    # Redirects user to OmniKassa
    render text: omnikassa.perform
  end
end

Response

class PaymentsController
  def create
    response = OmniKassa::Response.new(params)

    @order = Order.find(response.order_id)
    
    return if response.pending? # Payment is pending; serve an explanation to the customer

    if response.successful?
      @order.paid = true
      @order.save

      redirect_to root_url, success: "Payment succeeded"
    else
      redirect_to root_url, alert: "Payment failed"
    end
  end
end
