External Service

This plugin connects to PayKrypt, a third-party hosted cryptocurrency payment service, when a customer chooses PayKrypt at checkout and while WooCommerce synchronizes the resulting payment status.

To create a payment intent, the plugin sends the order total, currency, order number in the payment description, customer billing email address, configured allowed chains and assets, expiry, and amount tolerance to https://api.paykrypt.io. The merchant API key is sent in the Authorization header. During webhook-triggered, scheduled, and manual status synchronization, the plugin sends the PayKrypt payment intent ID to the same API. The returned intent ID, checkout URL, status, original amount and currency, last synchronization time, attempt count, and API error message are stored as private WooCommerce order metadata.

PayKrypt sends signed payment event payloads to the generated WordPress REST API endpoint. The plugin verifies the signature and timestamp before scheduling an authoritative status lookup. Scheduled polling remains active if webhook delivery is delayed or unavailable.

After the payment intent is created, the customer is redirected to PayKrypt hosted checkout at https://gate.paykrypt.io. PayKrypt may collect information from the customer under its own policies. The service is required for this plugin to process payments; no data is sent to PayKrypt until the merchant configures the plugin and a customer selects PayKrypt.
