Payzum Crypto & Stablecoin Payments for WooCommerce

Payzum lets your WooCommerce store accept cryptocurrency and stablecoin payments (USDC/USDT and
more, across multiple chains). Payments are non-custodial: funds settle directly to your own
wallet — Payzum never takes custody.

At checkout the buyer is redirected to a secure Payzum hosted checkout (QR + deposit address, live
status). Your order is marked paid automatically from a signed IPN webhook, so a closed browser tab
never loses a paid order.

Features:

• Crypto & stablecoin checkout (USDC/USDT, multi-chain).
• Non-custodial — settles to your wallet.
• Hosted checkout — no card data or crypto handling on your server.
• Signed IPN webhooks (HMAC-SHA-512) verify every payment server-side.
• No chargebacks.

External services

This plugin connects to the Payzum API to create payment invoices and receive payment
notifications. It is required for the gateway to work.

• What it sends: when a buyer chooses Payzum at checkout, the plugin sends the order total,
  currency, order id and your store’s callback/return URLs to Payzum to create the invoice.
  Payment confirmations arrive as signed webhooks from Payzum; the plugin verifies their
  signature before updating the order. No customer personal data is sent by the plugin.
• When: only when the gateway is enabled and a buyer pays (or the store owner tests the
  connection from the settings screen).
• Endpoints: https://merchant.payzum.com (production) or https://staging.payzum.com
  (staging), as selected in the plugin settings.
• Service provider: Payzum — terms, privacy.
