Payment gateway integrations for cryptocurrency and Pix

Technical documentation and pitches highlight different approaches to integrating payment gateways into e-commerce and hosting platforms.

SnapEX Pay provides a cryptocurrency payment gateway designed for WooCommerce and WHMCS modules. The system supports various currencies, including USDT on TRC20, ERC20, and BEP20 networks. To ensure security and reliability, the service utilizes signed webhooks with HMAC-SHA256 signatures, timestamp verification to prevent replay attacks, and an at-least-once delivery model with up to five retry attempts to handle duplicate or out-of-order events.

Separately, a lightweight PHP component has been developed for the Safe2Pay API. This tool facilitates transparent checkouts for Pix and credit card transactions. The component is designed for PHP 8.4, follows PSR-18 standards for HTTP clients, and utilizes typed exceptions for error handling. It supports sandbox and production environments, allowing developers to manage transactions, refunds, and webhooks without leaving their own websites.
