Member Subscription Payment Gateway Tutorial
WP-Admin->Restrict->Settings->Payments
Payment Gateway
The "Payments" settings tab is where you can configure your payment gateways and other settings.
If a user enters a discount code, then that code is checked for validity when the form is submitted. If the code is invalid, an error will be shown, and if the code is valid, then the discount will be applied to the membership price when the user is redirected to the payment gateway. If auto renewal is enabled and "one time" is not checked on then the discount price is also applied to all future payments.
The first two settings allow you to select your currency, and the currency symbol position (before or after the price).
The next section down allows you to select which payment gateway(s) you want to enable on the registration form.
Right below the gateway selection is a checkbox to toggle sandbox mode on or off.
Next you have to enter PayPal, 2Checkout, Authorize.net, Braintree payment settings.
Very easy to setp up things.
