External Services

This plugin connects to the Paymento API to process cryptocurrency payments. Paymento is a non-custodial payment gateway that enables WooCommerce stores to accept payments in Bitcoin, Ethereum, USDT, and other cryptocurrencies.

📌 Data Sent to Paymento API

The plugin makes exactly four types of request to the Paymento API, each with a specific trigger. No request is made on ordinary page views.

• Submitting Payment Requests

  • Endpoint: https://api.paymento.io/v1/payment/request
  • Triggered when a customer places an order and chooses Paymento at checkout.
  • Data sent: order total, currency, order ID, the return URL on your store, and your API Key.
  • Paymento returns a payment token used to generate the invoice.

• Payment Verification

  • Endpoint: https://api.paymento.io/v1/payment/verify
  • Triggered only when Paymento notifies your store of a paid order via webhook (IPN).
  • Data sent: the payment token for that order, and your API Key.
  • Used to confirm the notification is genuine before the order is completed.

• Fetching Merchant Information

  • Endpoint: https://api.paymento.io/v1/ping/merchant/
  • Triggered only when an administrator saves the gateway settings in WooCommerce.
  • Data sent: your API Key. Returns your registered merchant name and account status, which are stored locally and shown on the settings screen.

• Setting Callback URLs

  • Endpoint: https://api.paymento.io/v1/payment/settings/
  • Triggered only when an administrator saves the gateway settings, after the merchant check above succeeds.
  • Data sent: your store’s webhook (IPN) URL and your API Key, so Paymento knows where to send payment notifications.

📌 Customer Redirect

After an order is placed, the customer’s browser is redirected to https://app.paymento.io/gateway with the payment token for that order, where they complete the payment. No other customer data is included in the redirect.

📌 Data Received

Paymento sends payment status notifications to /wp-json/paymento/result on your store. Every notification is verified with an HMAC SHA256 signature using your Secret Key before it is processed.

🔗 Third-Party Policies

By using this plugin, your WooCommerce store communicates with Paymento API. You can review Paymento’s terms and policies here:

• Terms of Service: https://paymento.io/terms
