Most of them will only have 1 payment method called Webpay (A Chilean Payment Method) for which the plugin is already installed and can be configure from Magento Store Configuration. Each of the websites have a different merchant configuration (Merchant account, password, etc). Also there will be some websites with Webpay and PayPal at the same time. Configuration of Paypal also needed. 2.
