Overview

Description

The Gateway class is the base class for all ActiveMerchant gateway implementations.

The standard list of gateway functions that most concrete gateway subclasses implement is:

  • purchase(money, creditcard, options = {})

  • authorize(money, creditcard, options = {})

  • capture(money, authorization, options = {})

  • void(identification, options = {})

  • credit(money, identification, options = {})

Some gateways include features for recurring billing

  • recurring(money, creditcard, options = {})

Some gateways also support features for storing credit cards:

  • store(creditcard, options = {})

  • unstore(identification, options = {})

Gateway Options

The options hash consists of the following options:

  • :order_id - The order number

  • :ip - The IP address of the customer making the purchase

  • :customer - The name, customer number, or other information that identifies the customer

  • :invoice - The invoice number

  • :merchant - The name or description of the merchant offering the product

  • :description - A description of the transaction

  • :email - The email address of the customer

  • :currency - The currency of the transaction. Only important when you are using a currency that is not the default with a gateway that supports multiple currencies.

  • :billing_address - A hash containing the billing address of the customer.

  • :shipping_address - A hash containing the shipping address of the customer.

The :billing_address, and :shipping_address hashes can have the following keys:

  • :name - The full name of the customer.

  • :company - The company name of the customer.

  • :address1 - The primary street address of the customer.

  • :address2 - Additional line of address information.

  • :city - The city of the customer.

  • :state - The state of the customer. The 2 digit code for US and Canadian addresses. The full name of the state or province for foreign addresses.

  • :country - The [ISO 3166-1-alpha-2 code](www.iso.org/iso/country_codes/iso_3166_code_lists/english_country_names_and_code_elements.htm) for the customer.
