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](https://payzum.com/terms), [privacy](https://payzum.com/privacy). ### Credits Coin icons are from the open-source cryptocurrency-icons set (MIT license, spothq); a few network icons are original monograms bundled with this plugin. ## Installation 1. Upload the `payzum-crypto-payments` folder to `/wp-content/plugins/`, or install the zip via Plugins Add New Upload. 2. Activate the plugin. 3. Go to WooCommerce Settings Payments Payzum and enable it. 4. Paste your **API key** and **Webhook secret** from your Payzum dashboard. 5. Copy the **IPN URL** shown on the settings screen into your Payzum webhook settings. The IPN signature header is fixed (`x-nowpayments-sig`) — no configuration needed. 6. Save. Place a test order to confirm the flow. ## FAQ ### Is it custodial? No. Funds settle directly to your own wallet. ### Which coins are supported? USDC/USDT and other crypto across supported chains. Which coins your store accepts is configured in your Payzum dashboard (Merchants Settings Accepted tokens); the buyer picks one of those on the Payzum checkout. ### Do I need to write code? No. Enter your API key and webhook secret and you are live. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Payzum Crypto & Stablecoin Payments for WooCommerce” is open source software.

No functional change. * The internal version constant now matches the plugin version (1.5.1 left it at 1.5.0). #### 1.5.1 * Plugin URI now points at the plugin’s own repository, so it differs from the Author URI as the plugin directory requires. No functional change. #### 1.5.0 * The IPN now verifies the amount and currency paid against the order before it is completed. Nothing was compared before, so a payment for any amount completed the order in full; a mismatch now puts the order on hold for review instead. * An amount that cannot be read (missing, empty, or not a number) counts as a mismatch. The first version of this check treated an unreadable amount as “nothing to compare” and completed the order unverified. * A payment reference whose order suffix does not match the order it claims to pay is rejected. * The transition to complete is serialised with a database lock, so two deliveries arriving at once cannot both complete the order. * Lock names are scoped to the site’s database, table prefix and plugin. Lock names are global to the MySQL server, so the previous ones collided: two stores on one server blocked each other, and this plugin generated the same name as the Easy Digital Downloads and Paid Memberships Pro gateways. #### 1.4.0 * Rebuilt on the official `payzum/payzum-php` SDK (bundled in `vendor/`): HTTP client, webhook signature verification, decimal-exact amounts and the payment- status vocabulary now live in one tested library instead of plugin code. * IPN deliveries are deduplicated by their event id — retries can no longer add duplicate notes or re-fire the paid transition. * New Environment setting (production / staging) for end-to-end testing against the sandbox. * Order totals are sent with every digit intact (no float rounding on the wire). * Requires PHP 8.1 (the SDK’s floor). #### 1.3.0 * Cart & Checkout blocks support; HPOS compatibility declared. #### 1.2.0 * Modal and inline render modes via the Payzum widget; crypto currency mode (` pricing_mode: "direct"`). #### 1.1.0 * The buyer picks the coin on the Payzum hosted checkout (`pay_currency: "all"`); dropped the in-store coin picker. * IPN signature read from the fixed `x-nowpayments-sig` header. * Zero-total orders complete without an invoice; repeated IPNs no longer duplicate order notes; recurring signups are refused instead of being charged once. #### 1.0.0 * Initial release: hosted-checkout gateway with signed IPN verification. ## Meta * Version **1.5.2** * Last updated **1 day ago** * Active installations **Fewer than 10** * WordPress version ** 5.6 or higher ** * Tested up to **7.1.4** * PHP version ** 8.1 or higher ** * Tags * [cryptocurrency](https://wordpress.org/plugins/tags/cryptocurrency/)[payment gateway](https://wordpress.org/plugins/tags/payment-gateway/) [stablecoin](https://wordpress.org/plugins/tags/stablecoin/)[usdc](https://wordpress.org/plugins/tags/usdc/) [woocommerce](https://wordpress.org/plugins/tags/woocommerce/) * [Advanced View](https://wordpress.org/plugins/payzum-crypto-payments/advanced/) ## Ratings No reviews have been submitted yet.
