Authorize.net Parameters with activemerchant

I'm using authorize.net and activemerchant in a rails app.

When I make a purchase authorize.net sends back an email with information about the purchase. I should be able to send them the billing and shipping address information and have that returned in the email, but it's not returning any of the information, obviously I've got the varable names wrong, anybody know what they should be? I've been pouring over the authorize.net api docs and activemerchant's but can't find what I need.

My purchase method on an orders model looks like this:

def purchase
  purchase_options = {
    :ip                   => ip_address,
    :first_name           => first_name,
    :last_name            => last_name,
    :address              => billing_street_address,
    :city                 => billing_city,
    :state                => billing_state,
    :country               => "US",
    :zip                  => billing_zip,
    :ship_to_first_nam开发者_运维问答e   => first_name,
    :ship_to_last_name    => last_name,
    :ship_to_address      => shipping_street_address,
    :ship_to_city         => shipping_city,
    :ship_to_state        => shipping_state,
    :ship_to_country      => "US",
    :ship_to_zip          => shipping_zip
  }
response = GATEWAY.purchase(price_in_cents, credit_card, purchase_options)
# other transaction stuff
response.success?

end

The billing address variables are: x_first_name, x_last_name, x_company, x_address, x_city, x_state, x_zip, x_country, x_phone, x_fax

The shipping variables are: x_ship_to_first_name, x_ship_to_last_name, x_ship_to_company, x_ship_to_address, x_ship_to_city, x_ship_to_state, x_ship_to_zip, x_ship_to_country

You can omit any you do not wish to provide as they are all optional.

You can find these in the AIM Guide on pages 21 - 25.

Install fiddler and look at the raw response you are getting back. authorize.net should give you some hints on what is wrong.
