GF SagePay

This open-source add-on connects Gravity Forms to the SagePay payment gateway, enabling one-off payment processing through your forms. It is built for developers and site owners who need a reliable, self-hosted integration without recurring fees or third-party dependencies.

SagePay one-off payments: Accept single transactions directly through Gravity Forms, with order data sent to SagePay for a hosted checkout page.

Test sandbox support: Fully test your payment flow and fraud protection rules in SagePay's sandbox environment before going live.

HTTPS enforcement: The plugin encourages secure communication by recommending HTTPS for all payment-related traffic.

Customizable failure handling: Use the gf_sagepay_redirect_url_failure_wp_die filter to control what happens when redirect URL retrieval fails, such as continuing the form flow or redirecting to an error page.

Public API for confirmation URLs: Generate single-use, short-lived URLs to let users resume incomplete forms after SagePay checkout, without re-entering data.

Minimum requirements: PHP 7.2, cURL extension, and Gravity Forms 2.4.14.4 or later. Installation via Composer is recommended for easier updates and dependency management.
