S4D Payment Gateway with Thawani for WooCommerce

S4D Payment Gateway with Thawani for WooCommerce

Details
View on WordPress

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.
