Introduction

Hyperswitch is an open-source, high-performance payment switch designed to unify diverse payment methods. By integrating Hyperswitch with PrestaShop, we aim to provide e-commerce merchants with a flexible, cost-effective payment solution that enhances user experience and improves conversion rates.

Objectives

• Develop a PrestaShop module that seamlessly connects to Hyperswitch's API
• Enable merchants to process payments through various providers supported by Hyperswitch
• Implement essential payment flows (authorization, capture, refund, etc.)
• Ensure robust error handling and logging
• Provide a user-friendly configuration interface within the PrestaShop admin panel

Requirements

• The module should adhere to PrestaShop's development standards and best practices
• Utilize Hyperswitch's API documentation for integration
• Implement necessary security measures for handling sensitive payment data
• Ensure compatibility with PrestaShop versions 1.7.x and 8.x
• Support multi-language and multi-currency functionality

Deliverables

1. A fully functional PrestaShop module for Hyperswitch integration
2. Comprehensive documentation including:Installation guide
3. Unit and integration tests
4. Sample storefront implementation showcasing the payment flow

Architecture

The integration will consist of three main components:

1. Payment Module: Handles payment processing within PrestaShop.
2. Admin Configuration: Provides an interface for merchants to configure Hyperswitch settings.
3. Webhook Handler: Processes asynchronous notifications from Hyperswitch.

Implementation Details

Payment Module

• Implement as a PrestaShop payment module
• Handle payment creation and processing
• Communicate with Hyperswitch API for payment operations
• Map Hyperswitch responses to PrestaShop order statuses
• Implement error handling and logging

Admin Configuration

• Create a configuration page in the PrestaShop admin panel
• Allow merchants to input Hyperswitch API credentials
• Provide options to configure payment methods and settings
• Implement validation for configuration inputs

Webhook Handler

• Create an endpoint to receive webhooks from Hyperswitch
• Process incoming notifications and update corresponding orders in PrestaShop
• Implement security measures to validate webhook authenticity
• Ensure idempotency to handle duplicate notifications
