    What is Prestashop?

    How Payment Gateways Work in PrestaShop

    PrestaShop has an advanced payment module architecture that standardises how payment gateways integrate with the platform. Instead of directly interacting with the core code, payment modules register hooks to insert payment options before order validation.  

    Once customers select a payment method, the module processes the payment via the gateway and updates the status to PrestaShop.This architecture offers flexibility to add/remove modules without affecting core files.  

    Steps to Integrate a Payment Gateway

    Follow these key steps to integrate a payment gateway for your PrestaShop store:

    Step 1: Get Gateway Credentials

    First, you must sign up for a merchant account with your preferred payment gateway provider. This gives you API keys, authentication codes and other credentials to access their payment infrastructure.

    Step 2: Install Payment Module

    PrestaShop has free and paid modules for popular payment gateways. Install the module for your selected gateway from the module catalogue in your admin back office.

    Step 3: Configure Credentials

    Once installed, paste the API credentials, merchant ID, public/private keys, etc., in the module settings as provided by the gateway. Save configuration.

    Step 4: Test Transactions

    Initiate some test transactions using dummy card numbers. Most gateways have a sandbox/demo mode for testing flows. Verify transactions that are passing through correctly.

    Step 5: Go live!

    Finally, switch the gateway to live mode whenever you can accept real payments. Monitor a few live transactions closely before the full launch.   As seen above, payment gateways don’t directly integrate with PrestaShop’s core code. Instead, the integration happens through intermediate payment modules.

    Benefits of Integrating a Payment Gateway

    • Accept payments instantly: With a payment gateway, you can start accepting payments when a customer orders. This leads to faster checkout and improved customer experience.
    • Access global payment methods: Gateways allow you to accept payments through multiple channels like cards, wallets, EMIs, net banking, etc. This gives more payment options to international customers.
    • PCI compliance: Gateways ensure all card data flows through secure channels. This saves you from undergoing tedious PCI compliance certification.
    • Seamless integration: PrestaShop offers seamless integration with over 100 payment gateways. You can get started with payments quickly.

    A Brief Overview Of Prestashop’s Payment Module Architecture:

    1. Registration of Hooks

    Payment modules use hooks to insert payment options before order confirmation.

    • hookPaymentOptions: Registers payment method in checkout
    • hookPaymentReturn: Redirects back to store post payment

    2. PaymentOption Object

    This crucial object defines all aspects of the payment method:

    • Name, description & logo
    • Payment form/iframe configuration
    • Backend actions like order management

    3. Standardised Flows

    Common payment flows are standardised for consistency.

    • Offline payments (bank transfers, etc.)
    • Online redirect to gateway site
    • Embedded forms (direct card capture)

    4. Extensibility

    The architecture allows adding new payment modules without needing core upgrades.  

    Developing a Custom Payment Module

    While PrestaShop has modules for popular gateways, you may need to build a custom module for a specialised provider.  

    Here are the key steps:

    1. Set up Module Skeleton

    Begin with the module skeleton, which contains the basic folder structure, descriptor file, classes, and hook registration:


    2. Define PaymentOption

    This class will hold payment method details like name, form fields, etc. Display logic can be separated:
