PayPal Gateway Module: Accept Global Payments

Last updated on May 21, 2026 05:10

PayPal is one of the most widely used and trusted digital payment platforms in the world. By enabling the PayPal Gateway Module in PolyCMS, you can accept payments via PayPal balances, bank accounts, and major credit cards directly on your checkout page.

This module integrates the latest PayPal REST API, providing a seamless, redirect-free checkout experience.

Installation and Configuration

  • Enable the Module: Navigate to Settings > Modules, locate the PayPal Gateway module, and click Enable.

  • Access Gateway Settings: Go to Settings > Payment Gateways and click on PayPal.

  • Toggle Active: Switch the status toggle to Active.

Obtaining API Credentials

To connect PolyCMS to PayPal, you need your unique API keys.

  • Log in to the PayPal Developer Dashboard.

  • Navigate to Apps & Credentials.

  • Click Create App and give it a name (e.g., "My PolyCMS Store").

  • You will be provided with two crucial pieces of information:

  • Client ID * Secret Key

Copy these keys and paste them into the corresponding fields in your PolyCMS PayPal settings.

Sandbox vs. Live Environments

The PayPal module supports two operating modes:

  • Sandbox Mode: Use this during development and testing. It connects to PayPal's simulated environment. You can create dummy buyer accounts in the PayPal Developer Dashboard to test making purchases with fake money. Always test your checkout flow in Sandbox mode first!

  • Live Mode: When you are ready to accept real money from real customers, switch the environment dropdown in PolyCMS to "Live" and ensure you have pasted your Live Client ID and Secret (they are different from your Sandbox keys!).

Order Processing Workflow

When a customer selects PayPal at checkout:

  • They click "Place Order" and a secure PayPal popup appears.

  • They authorize the payment.

  • PayPal instantly sends an automated background message (a Webhook) back to PolyCMS confirming the funds are secure.

  • PolyCMS automatically changes the Order Status from "Pending" to "Processing".

  • The system automatically sends an Order Confirmation email to the customer.

This entire process happens in seconds, requiring zero manual verification from the store owner!
