2 of 5 measures had too little evidence to score. They are left out of the total rather than counted as zero — otherwise a plugin would be marked down for being small rather than for being poorly kept.Measured 2026-08-01 from the WordPress.org plugin registry.
Ratings

No one has rated this plugin on WordPress.org yet. That is a statement about the ratings page, not about the plugin — plenty of well-kept plugins never collect them.

The Shift4 for WooCommerce plugin enables payments in your WooCommerce store using two methods: Apple Pay and card payments processed by Shift4. By leveraging this plugin, you will be able to accept payments safely and securely.

Features:
* Credit Card Payments
* Saved Cards
* Apple Pay
* 3D Secure
* Full & Partial Refunds
* Automatic settlement or authorise-only transactions
* WooCommerce Classic Checkout
* WooCommerce Block-based Checkout
* Order via admin
* Fraud detection and prevention

Configuration

WooCommerce > Settings > Payments

This configuration is shared across both Card and Apple Pay sections, therefore it only needs to be updated and configured in one area and the settings will be shared.
* Public Key – Your Shift4 account Public Key. This can be located in your Shift4 account under Account Settings > API Keys.
* Secret Key – Your Shift4 account Secret Key. This can be located in your Shift4 account under Account Settings > API Keys.
* Capture Strategy – To set the capture of the payment to be immediate or set it to authorise-only to be captured manually later.
* Debug Logging – With debug logging enabled, all data about charge requests will be recorded to Shift4_Payments so that unexpected behaviour can be identified. When debug is disabled, decline responses will still be recorded.
