✅ Product Overview

The Iyzico Payment Gateway Addon, designed specifically for Downgrade, provides a critical bridge for WordPress sites managing subscription-based services in regions where Iyzico is a preferred payment method. This plugin is essential for administrators using the Downgrade core plugin to manage recurring access levels, and needing to offer secure, local payment processing through Iyzico. It targets businesses and creators in Turkey and surrounding areas, ensuring subscribers can complete transactions smoothly. Its core use is enabling Iyzico as a direct payment option within the existing Downgrade checkout flow.

Upon installation and activation, the setup process was straightforward. Navigating to the Downgrade settings panel, a new tab or section titled “Payment Gateways” or “Iyzico” appeared. Here, you find input fields for your Iyzico API Key and Secret Key, standard credentials obtained from your Iyzico merchant account. There’s a toggle to enable/disable the gateway and an option for “Sandbox” mode during testing. Once configured and saved, the Iyzico Payment Gateway Addon for Downgrade option becomes visible on your subscription purchase forms, allowing users to choose it alongside other methods.

✅ Technical & Compatibility

This payment gateway integrates directly with the Downgrade plugin’s architecture, extending its functionality. It registers itself as a new payment method within Downgrade’s system. When a user selects the Iyzico Payment Gateway Addon during checkout, the system generates a secure payment request. This redirects the customer to the Iyzico payment portal for card details. Post-payment, Iyzico communicates transaction status back to your WordPress site, updating the subscriber’s status within Downgrade. Compatibility is explicitly tied to the Downgrade core plugin; it won’t function independently.

I found the plugin handles currency conversion and transaction statuses effectively. If payment is successful, the Downgrade user’s subscription automatically activates or renews. If an issue occurs during the Iyzico transaction, the user is redirected back to your site with an error, and their Downgrade subscription status remains unchanged. This ensures a clear flow for both successful and failed payments.

The integration respects Downgrade’s existing subscription logic for upgrades and downgrades. If a user changes their subscription level, the Iyzico gateway facilitates the new payment amount or cancellation based on Downgrade’s handling. This is especially useful for maintaining seamless billing flows for Downgrade subscriptions.

✅ FAQ & Tips

Q: How do I get my Iyzico API keys? You need an active merchant account with Iyzico. Log into your Iyzico panel, usually under “Settings” or “API Information,” to retrieve your API Key and Secret Key.

Q: Does it support recurring payments? Yes, the plugin leverages Iyzico’s capabilities to handle recurring transactions, which is fundamental for any subscription-based system. This functionality is a key reason to implement the Iyzico Payment Gateway Addon for Downgrade on your site.

Q: What if a payment fails? The user is typically returned to your checkout page with a notification. Their Downgrade subscription will not activate or renew until a successful payment is made.

To ensure smooth operation, always test your checkout process thoroughly in Sandbox mode before going live. Make dummy purchases with test card details provided by Iyzico to confirm the entire flow, from selection to subscription activation, works as expected.
