Ninja Forms Authorize.net

Ninja Forms Authorize.net is an official extension of the Ninja Forms ecosystem that connects your WordPress forms with the Authorize.net payment gateway. Its purpose is to allow your site visitors to make credit card payments directly from a form, without redirects to external pages or the need for a shopping cart.

This extension is designed for small businesses, non-profit organizations, freelancers, and developers who need to charge on a one-time or recurring basis within a flexible form flow. It is ideal for managing bookings with advance payment, donations, membership fees, budgeted services, or one-time payments, all centralized in a clean and customizable form experience.

Configuration is simple and requires no technical knowledge. You only need an Authorize.net account, copy your API keys into the Ninja Forms settings, and add an Authorize.net action to any form. The extension includes test (sandbox) and production (live) modes, allowing you to validate the entire flow before launching it on your site.

• Accept credit card payments directly in your WordPress forms, without redirects.
• No-code setup using drag-and-drop tools.
• Support for fixed-value payments, user-entered amounts, or automatically calculated totals.
• Sandbox and live modes to test transactions safely.
• Secure handling of sensitive data and compliance with privacy regulations such as GDPR.
• Compatibility with recurring payments and trial periods.
• Native integration with the Ninja Forms form builder, including email notifications, custom redirects, and submission management.

By eliminating the friction of manual payment processes, this extension reduces transaction errors, improves the customer experience, and allows you to scale your operations without technical complications. If you already use Ninja Forms on your site and need to charge professionally, this is the official solution that keeps everything within your own form flow.
