Once you have installed Payage and some gateway addons you need, you need to create one or more gateway accounts, so that when an application requests payment buttons, Payage can provide them. Each gateway account produces one payment button.
If you already have some experience with online payments you can probably just setup a Payage account for your live gateway account(s). You will probably want to perform a test transaction in your application using real money which you can subsequently either refund or transfer to your bank.
If you are new to online payments, or you want to explore the possibilities more thoroughly, you can setup a pair of test accounts for your chosen gateway. Most payment gateways provide test accounts. These allow you to perform as many test payments as you like without using real money.
If you want to bypass the payment issues and just explore your application, you can setup an "Offline" gateway account. This account type does not interact with any payment gateway, it merely produces a payment button that records a pending payment as soon as the button is clicked. The idea is that the customer then contacts the site and makes the required payment by bank transfer or by telephone. Once the payment is confirmed, the administrator can change the payment status to successful. This type of payment does not make sense for all applications, but is suitable for some types of business.
To setup a real payment gateway account, you must complete four steps
Every payment gateway works differently, so you will need to follow the instructions carefully and invest some time learning about each gateway that you use.
Each type of payment gateway has a slightly different setup page in Payage. The common items are described in the next section, but each gateway type also has its own specific section or document. Gateway addons provided by Remository Software are all described in this document. Third party gateway addons should have their own separate document.
