Monkeys Commerce Square

MonkeysCommerce Payment: Square

Square payment integration with the Web Payments SDK. PCI-compliant on-site card tokenization, Apple Pay, Google Pay, ACH direct debit, and delayed capture support.

This is an official payment gateway for MonkeysCommerce. It implements the PaymentGatewayInterface plugin system — providing createPayment, capture, refund, and handleWebhook methods.

Features

• Web Payments SDK: Tokenize credit cards securely in the browser — card data never touches your servers (PCI-DSS compliant).
• Digital Wallets: Built-in support for Apple Pay and Google Pay buttons.
• ACH Direct Debit: Accept US bank account payments.
• Delayed Capture: Authorize at checkout, capture when you ship.
• Omnichannel: Seamlessly integrates with Square's physical POS ecosystem via the mkc_pos module.
• Lightweight: Built directly on Guzzle HTTP — no bulky Square SDK dependency.
