Description

The Authorize.Net gateway adds to Formidable Forms payment processing for credit cards (via Authorize.Net AIM) and eCheck (bank account debit), connecting to the merchant account using API Login ID, Transaction Key and Signature Key. The integration allows single transactions in sandbox mode for testing and live environment for production, with automatic creation of a Payment Gateway field that conditionally displays the specific fields for each method selected by the customer.

Main Features

  • Credit card via AIM
    Processes card transactions using Authorize.Net’s AIM method directly in the form.
  • eCheck Payment
    Accepts account debit with collection of routing number, account and bank name.
  • Protected API Credentials
    Connects the form using the merchant’s API Login ID, Transaction Key and Signature Key.
  • Sandbox and Production Mode
    Switches between developer.authorize.net test environment and real live charging.
  • Conditional Payment Gateway Field
    Automatically generates a selector that displays the fields of the chosen method by the customer.

Benefits of Authorize.Net

  • Payment on the form itself
    Receives payments without redirecting the customer to an external checkout or other platform.
  • Pre-go-live validation
    Tests the entire flow in sandbox before processing real amounts.
  • Post-payment automation
    Triggers emails, SMS via Twilio and syncs with MailChimp after transaction approval.
  • Receiving flexibility
    Accepts card and eCheck on the same form, meeting distinct customer preferences.

Who is it suitable for?

  • Merchants who already have an Authorize.Net account and want to use the platform directly in WordPress forms.
  • Professionals, consultancies and non-profit organizations that charge memberships, donations or services via form.
  • Companies in the United States that need to accept eCheck and credit card without building a full e-commerce structure.

Designed for those operating in the United States with an active Authorize.Net account, the component concentrates billing and data collection into a single flow within Formidable Forms, eliminating intermediate integrations. The combination of mandatory SSL, post-transaction conditional actions and simultaneous support for card and eCheck covers the receipt cycle from form submission to customer notification and marketing tool sync.
