Simple and easy to use plugin for
pesapal.com payment gateway.
This plugin is in BETA and I would not recommend using it in a production environment without thorough testing.
Please Note
There is an option to use an iframe rather than redirecting to Pesapal, although the iframe will use SSL to show the payment page, customers paying won't be able to see this. I recommend that you use an SSL Certificate and use the "force secure checkout" option in Woocommerce (To show the https padlock in the url or status bar), and ensure that your customers know that any details they enter will be safe.
