To implement Paygent API requests and webhook processing in WooCommerce, you can unify API transmission, authentication, and webhook reception using a standardized wrapper for deterministic operation across all payment methods. It handles telegram_kind-based flows and error management.

WooCommerce can support SJIS encoding conversion for Paygent webhooks by applying automatic SJIS to UTF-8 transformation during REST API reception. This ensures standardized error detail management and correct character handling for incoming payment data.

Paygent hash checking works for preventing payment data tampering by appending hc and request_date parameters, then generating a SHA-256 hash in a specified order. This guarantees data integrity when enabled for the payment request.

You can manage multiple Paygent environments and merchant IDs for WooCommerce multi-site by switching merchant_id, connect_id, and connect_password between test and production. It also accounts for site_id configurations for multi-site setups.

The best way to map Paygent trading_id to WooCommerce order IDs is by determining the trading_id based on stored _paygent_order_id values or prefix-based generation, using payment_id and trading_id as processing keys.

The Paygent payment gateway core requires WooCommerce 9.0+, WordPress 6.7+, and PHP 8.2+ for compatibility. It utilizes the PaygentB2BModule from vendor-wc to implement required options and endpoint behaviors.
