iATS Payments Gateway for Gravity Forms
iATS Payments offers simple, web-based credit card processing services for nonprofit organizations that help you easily process transactions from all major credit cards, and save you time and money by streamlining your fundraising processes. This plugin enables you to use the iATS Payments gateway to accept credit cards directly via the custom forms on your Gravity Forms powered website without redirecting customers away to the gateway website.
Like all WP Gateways extensions, this plugin installs with one click. After installing, you will have only a few fields to fill out before you are ready to accept credit cards on your store.
This payment gateway allows you to accept credit cards directly on your website, so in order to remain PCI Compliant you must protect the checkout page with SSL. However, the plugin will function with or without SSL on.
