NormiePay Crypto Checkout

NormiePay is a non-custodial crypto payment gateway. This plugin lets your WooCommerce store accept USDC on Base and Polygon. Each order redirects to a hosted NormiePay checkout; when the payment confirms on-chain, a signed webhook marks the order paid automatically.

• Non-custodial — funds settle on-chain directly to your wallet via smart contract
• USDC on Base & Polygon (the customer picks at checkout)
• One-click webhook setup — just paste your API key and save
• Signed (HMAC-SHA256) webhooks verify every payment
• Automatic on-chain refunds for over/underpayment

External services

This plugin connects to the NormiePay API (https://normiepay.xyz) to process crypto payments. NormiePay is required for the plugin to function; you provide your own NormiePay API key in the settings.

What is sent, and when:

• When a customer places an order and chooses this payment method, the order amount, the customer’s email, and the order id/key are sent to https://normiepay.xyz/api/v1/checkout/sessions to create a hosted checkout session.
• When you save the plugin settings, your store’s webhook URL is sent to https://normiepay.xyz/api/v1/webhooks to register it (one time).
• NormiePay sends a signed webhook back to your store (verified with HMAC-SHA256) to mark the order paid.
• The payment method icon is loaded from https://normiepay.xyz/icon.svg.
