Extension Overview

ExtraPay is engineered specifically as a native extension for modern Joomla installations. It takes complete advantage of the Joomla 5/6 framework architecture, strictly avoiding legacy behaviors, non-standard library bundlers, or obfuscated code.

ExtraPay standardizes online payment processing across Joomla applications. Instead of managing disparate, fragile payment plugins with incompatible webhook formats, ExtraPay provides a single, unified adapter architecture.

Includes production-ready adapters for Lemon Squeezy, Paddle Billing, Stripe Checkout, and PayPal. All webhooks verify cryptographic signatures and enforce strict idempotency to prevent duplicate charges or double entitlements.

Never store raw credit card data on your servers: 100% compliant with PCI DSS SAQ-A requirements.

1-Click Native Joomla Updates (Download IDs)

Like all Codextra extensions, ExtraPay integrates directly with the official Joomla Update Manager using Download IDs (DLID):

# Configuring 1-Click Updates in Joomla 5.x / 6.x:
1. Go to: Joomla Admin → System → Update Sites
2. Locate: "ExtraPay Update Site"
3. Enter your 32-character Download ID in the "Download Key" field
4. Click "Save & Close"

When an update is released, Joomla will alert you in the administrator dashboard, allowing 1-click upgrades with SHA-256 integrity verification.
