Square Payment Gateway Module for WHMCS

Square Payment Gateway Module for WHMCS

Developed By hoXtPro

Compatible with WHMCS v9.0

“Limited: $19.99 first year with code 20inFebruary (renews $79). New signups only. Ends 2026-02-28."

Automate your sales flow by taking full advantage of the powerful Square API at no additional subscription cost.

"This module is a swiss army knife! Once I stopped seeing it as just a payment link but as a malleable APP and let it take full advantage of the API—let it pull its weight—I could focus on growing, not creating links, sending license renewals, or managing subscriptions." WNH dev@ hoxt.pro

What It Does

  • White Label: Fully customizable for developers, or request free installation/updates from our team
  • Automatically searches Square Orders by reference_id to mark invoices paid
  • Includes branded invoice card, callback handler, and whmcs.json metadata
  • No card data handled by WHMCS; uses Square Orders and Payments scopes
  • No demo required. This is a production-ready implementation used at checkout.
