External Services

This plugin connects to one external service, required to process payments. It does not load third-party fonts or scripts, and it does not collect analytics.

CeyPay Payment API (Required)

When a customer initiates a payment, this plugin sends order information to the CeyPay payment processing API to generate QR codes and process transactions. This is required for the plugin to function.

• Service provider: CeyPay
• Service URL: https://api.ceypay.io/ (production) and https://sandbox-api.ceypay.io/ (test mode)
• Privacy policy: https://ceypay.io/privacy
• Terms of service: https://ceypay.io/legal/terms
• Data sent: Merchant ID, order number, order total and currency, the name of each item in the order, and the customer’s billing details (first and last name, email address, phone number, street address, city, postal code and country)
• When: Every time a customer selects a payment provider at checkout, and when the resulting payment status is polled
• Also sent: The store’s webhook callback URL, so CeyPay can notify the site when payment completes

The payment modal displays the notice “By continuing, you agree to our Terms of Service & Privacy Policy”, linking to the two documents listed above. These are the terms governing the payment the customer is about to make through CeyPay, and the notice appears only inside the modal, after the customer has chosen CeyPay at checkout. It is a disclosure required for the transaction, not promotion of the service. The optional “Powered by CeyPay” credit is separate: it is off by default and shown only if the store owner enables it in the gateway settings.
