WooCommerce Payment gateways

Allows customers to pay using several payment gateways:
* Authorize.net – Credit card only.
* PayU (Latin America) – Credit card + offline payments on 7-Eleven, Oxxo’s.

Hooks

Two hooks are exposed, for a basic workflow in which the order needs to be marked as complete or users will send a
receipt for offline payments, these hooks are not needed, they are meant for more complex and custom workflows.

• gp_order_online_completed_successfully – This hook is triggered when the payment is completed. Sends an array with
  the gateway’s response information and the order ID to the callback.
• gp_error_occurred – This hook is triggered when an error occurs during the payment process. Sends the exception
  to the callback.
