Overview

The plugin turns a Ninja Form into a payment form connected to Authorize.net. Visitors can pay by credit card on the site, without being sent to another page. This suits site owners who want to collect payment alongside form submissions for things like event registrations, product sales, or donations.

Forms can collect one-time or recurring payments, with fixed amounts, customer-entered amounts, or totals calculated within the form. Sandbox mode lets site owners test payment workflows, while live mode handles transactions. Transaction data and logs are available in Ninja Forms for reviewing payments and diagnosing submission or card verification errors.

Features

  • On-page card payments: Connect a Ninja Form to Authorize.net so visitors can submit credit card payments directly on your site without a redirect.
  • One-time and recurring payments: Collect a single payment or set up recurring billing with customizable payment intervals and quantities. Recurring payments can include a trial period.
  • Flexible payment amounts: Set a fixed amount, let customers enter their own payment or donation amount, or calculate a total within the form.
  • Sandbox and live modes: Use sandbox mode to test payment workflows before processing transactions in live mode.
  • Transaction records and logs: Review transaction data and logs in Ninja Forms to track payments and investigate card verification or form submission errors.
  • Payment method choices: Combine the PayPal add-on with Conditional Logic to let visitors choose between credit card and PayPal payments in one form.
