Fusion Pay by tbi bank

Fusion Pay by tbi bank adds tbi bank financing to WooCommerce stores, letting eligible customers apply for installment or Buy Now, Pay Later payments during the shopping journey. The integration is designed for merchants working with tbi bank and supports the full purchase flow, from product discovery to checkout. Key features:

• tbi bank payment gateway for WooCommerce checkout
• Financing buttons on product and cart pages
• Installment calculator popup for available payment plans
• Support for installment loans and BNPL flows
• Multi-country setup for Bulgaria, Romania, and Greece
• Country-specific configuration and feature flags
• API-based merchant credential validation and status sync
• WooCommerce Blocks checkout compatibility
• Compatibility with selected WooCommerce product option and bundle extensions

This plugin requires an active WooCommerce installation and valid tbi bank merchant credentials.

3.3

• Removed the bundled SuisseIntl font files (unused, and not licensed for redistribution); the plugin already uses the GPL-compatible "Inter" webfont for checkout styling.
• Disclosed the Google Fonts request in the External Services section of this readme.
• Fixed mismatched Stable tag in readme.txt (WordPress.org automated check).
• Added nonce verification to the cart, installment calculator, and session-data AJAX handlers.
• Renamed remaining unprefixed options, functions, and hooks to the fusipatb_ prefix, with a one-time migration of existing merchant settings.
• Replaced the open permission_callback on the /api/tbi/v1/tbi-api-gateway REST route with signed-request authentication: callers must provide a timestamp, a nonce, and an HMAC-SHA256 signature over the request; requests outside the clock-skew window, with an invalid signature, or with an already-used nonce (replay) are rejected before decryption. The Origin allowlist and IP allowlist remain as additional defense-in-depth layers.
• Fixed the activation/deactivation status ping incorrectly firing on a fresh install with no merchant credentials configured yet (a false-vs-'' comparison bug meant the "no credentials" guard never triggered), so the plugin no longer contacts the tbi bank status endpoint before the merchant has entered credentials.
• Sanitized TM Global Extra Product Options checkbox labels before they are appended to the product name and sent in the financing payload.
• The plugin now checks for WooCommerce before loading its autoloader/bootstrap and shows a dismissible admin notice (instead of a fatal error) when WooCommerce is missing or inactive.

3.2.1

• Update the flexible fusion pay logic to properly cehck for qty changes on page.

3.2

• Updated references from TBI_TEST_ENV to FUSIPATB_TEST_ENV and TBI_PLATFORM_URL to FUSIPATB_PLATFORM_URL across all country configs.
• Replaced TBI_ADVERTISEMENT_PAGE and TBI_WC_PLUGIN_PATH with FUSIPATB equivalents in Advertisement and BlocksCartIntegration.
• Updated logo and CDN references in CartButton and ProductButton.
• Refactored FrontendAssets and Popup to use FUSIPATB paths.
• Adjusted BlocksGateway and PaymentGateway for FUSIPATB constants.
• Enhanced SecurityHelper for IP validation and origin checks.
• Cleaned up StatusColumn and uninstall.php.
• Bug fix for Romania.

3.1

• Added WooCommerce Blocks cart support: TBI installment button now renders inside Blocks-based cart themes via BlocksCartIntegration.
• Added add-to-cart handling for Romania (RO) in CartProcessor and ProductProcessor.
• WordPress.org plugin review compliance: prefixed AJAX action slugs (fusipatb_*), sanitized $_POST/$_COOKIE/$_SERVER inputs, replaced inline <script> with wp_add_inline_script().
• Renamed gateway classes to Fusipatb_PaymentGateway and Fusipatb_BlocksGateway; backward-compat aliases retained for one release cycle.
• Removed build/build-branch-zips.sh (not permitted on WordPress.org).

3.0
