External Services
This plugin relies on an external service — the K Khay Payment Gateway API (https://api.kkhay.com or your configured self-hosted gateway instance) — to create cryptocurrency payment invoices, track real-time blockchain settlement, and verify payment webhook signatures.
- What the service is: K Khay Sovereign Crypto Gateway provides non-custodial cryptocurrency checkout processing (USDT, USDC, BNB, ETH on BSC, Polygon, Arbitrum, Base, and Ethereum).
- What data is sent: When a customer selects K Khay at checkout and places an order, the plugin transmits order details including the order ID, payment amount, currency, return/cancel URLs, and your merchant API credentials to initiate the checkout session. Sensitive customer payment credentials (such as credit card numbers or private keys) are never requested, stored, or transmitted.
- When data is sent: Data is transmitted when a customer initiates payment at checkout, when invoice status is queried, and when receiving webhook payment callbacks.
- Service Provider: K Khay (https://kkhay.com)
