Welcome to the Paystack WHMCS plugin repository on GitHub.

Here you can browse the source code, look at open issues and keep track of development.

Installation

Requirements

• Existing WHMCS installation on your web server.
• Supported Web Servers: Apache and Nginx
• PHP with the 21 Oct 2026 security fixes for critical remote code execution flaws (GHSA-w8hw-w9fx-j79w, GHSA-6wmf-4rv5-p3rp; php.net advisory): 8.2.35, 8.3.36, 8.4.27, 8.5.12 or later. Pick a version your WHMCS release supports. PHP 8.1 and older no longer receive security fixes, so if your WHMCS release can't run a patched PHP, upgrade WHMCS first.
• PHP extensions required by WHMCS, MySQL and a web browser
• cURL (7.34.0 or more recent)
• OpenSSL v1.0.1 or more recent
