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.

Originally a paid plugin developed by The Source for Development (https://www.s4d.om), rewritten with Claude Code and released as open source.

Features:

  • Hosted Thawani checkout — customers redirect to Thawani’s secure checkout page; PCI scope stays with Thawani.
  • Saved cards — logged-in customers can tokenize cards on Thawani and reuse them at checkout.
  • Refunds — full refunds from the WooCommerce admin (Thawani does not support partial refunds).
  • Webhooks — optional server-to-server endpoint so payment status syncs even if the customer closes the page before redirect. Optional HMAC-SHA256 signature verification.
  • WooCommerce Blocks support and HPOS compatibility.
  • Currency conversion hook (thawani_gateway_convert_to_omr) for non-OMR stores.

External services

This plugin connects to Thawani Pay, the payment gateway operated by Thawani Technologies LLC (https://thawani.om), to process card payments for your WooCommerce store. Using this plugin requires a Thawani merchant account and API keys, which you enter in the gateway settings. Thawani is a third-party service and is not affiliated with this plugin’s authors.

The plugin communicates with Thawani’s API endpoints (https://checkout.thawani.om in live mode and https://uatcheckout.thawani.om in test mode) in the following situations:

  • When a customer places an order with this gateway, a checkout session or payment intent is created. The data sent includes the order amount and currency, product/line-item names, a client reference derived from the order ID, and your merchant API key (sent as a request header). The customer is then redirected to Thawani’s hosted checkout page to enter their card details — no card data is handled or stored by your site.
  • When a logged-in customer reuses or deletes a saved card, the plugin creates/retrieves a Thawani customer record and its stored payment methods. The data sent is a customer identifier and your merchant API key.
  • When a store administrator issues a refund, the plugin looks up the payment and sends a refund request containing the payment ID, amount, and reason.
  • If you configure the optional webhook, Thawani sends payment-status notifications back to your site, which the plugin verifies (optionally via HMAC-SHA256) and uses to update the order.

No data is sent to Thawani except as part of these payment operations.

  • Thawani Terms and Conditions: https://thawani.om/terms/
  • Thawani Privacy Policy: https://thawani.om/privacy-policy-2/

Does Thawani support partial refunds?

No. Refund attempts that don’t match the order total are rejected with a clear error.

Will my legacy settings carry over?

Yes. The settings option key (woocommerce_thawani_settings) and the legacy mapping table ({prefix}thawani_invoice_map) are preserved.

How do I test?

Enable Test mode in the gateway settings. The form ships with public Thawani UAT credentials.
