The plugin sends data to OmniNext Exchange only as part of payment gateway setup, payment processing, product synchronization, stock reservation, order notifications, and supported WooCommerce event handling. Depending on the operation, the data sent may include the OmniNext Exchange connection ID, WooCommerce site URL, wallet/store ID and wallet type, WooCommerce order ID and order number, order status, currency, total, transaction ID, customer name and email, billing and shipping name, address, phone, and email, product ID, variation ID, product name, SKU, quantity, price, subtotal, total, descriptions, categories, tags, attributes, stock status, stock quantity, images, permalink, invoice ID, payment status, payment method, payment timestamps, stock reservation expiration time, and order email recipient details.

Data may be sent when administrators fetch stores and connected wallets, fetch the configured commission rate, synchronize WooCommerce products, or when a customer creates a payment invoice. Data may also be sent while checking or refreshing invoice status, reserving inventory for an unpaid invoice, requesting order notification emails, or processing supported WooCommerce events such as order creation, order status changes, customer creation, stock changes, price changes, and logged-in cart additions.

The plugin sends API requests only to the OmniNext Exchange backend. It does not directly call the underlying blockchain checkout APIs. Customers may be redirected to a payment page returned by the OmniNext Exchange backend.

OmniNext Exchange may use independently deployed payment services to create invoices, display payment pages, derive or display payment addresses, monitor blockchain transactions, and report payment status:

Solana Payments: https://solana.omninexttech.com
Solana Stablecoin Payments: https://solana-stable.omninexttech.com
Ethereum Payments: https://ethereum.omninexttech.com
Ethereum Stablecoin Payments: https://ethereum-stable.omninexttech.com
Bitcoin Checkout: https://pay.omninexttech.com

These payment services are not called directly by this plugin. OmniNext Exchange may provide them with store ID, store name, merchant public wallet address or Bitcoin extended public key, invoice ID, payment amount, currency or stablecoin, order ID and description, selected order metadata, redirect URL, payment expiration time, and transaction ID when a payment is detected.

For Bitcoin Checkout, addresses are derived from the merchant’s public extended key. Private keys, seed phrases, xprv values, and tprv values must never be sent to OmniNext Exchange or its payment services.

OmniNext Exchange and its payment services may use blockchain RPC/node providers, explorers, and price-feed APIs to process payments and verify transactions. These may include Solana Mainnet RPC, Solscan, Ethereum JSON-RPC or Alchemy, Etherscan, Blockstream Esplora, and CoinGecko for fiat-to-cryptocurrency conversion. Checkout pages may also load resources from Google Fonts, jsDelivr, and QRServer if those resources are used by the hosted payment pages.

OmniNext Exchange is non-custodial. Cryptocurrency payments are sent directly from the customer’s wallet to the merchant’s configured wallet address. OmniNext Exchange and its checkout services create invoices, display or derive payment addresses, monitor blockchain transactions, and report payment status, but they do not receive or custody customer funds.
