Przelewy24 payments where a ready plugin cannot reach: your own store, client panel, app, booking system or subscription. With server-side verification of every payment, refunds and BLIK.
The customer returning to your site confirms nothing. The notification and a server-side verification decide.

Przelewy24 resends the notification until the transaction is verified. The schedule is fixed and documented.
The notification addressA notification without a verified transaction comes back on the next attempt, with the same parameters.
This is how we run a payment on your order. The upper lane holds the events at Przelewy24, the lower one the order status, which turns paid only after verification.
The amount, the notification address and a signature with the panel key.
Transaction registered, the customer has the payment link.
By transfer, BLIK or card on the payment page.
The customer is on the payment page or confirming BLIK in the banking app.
The customer cancelled or time ran out. The order waits for another attempt.
Sent even if the customer did not come back.
A notification arrived, but the amount and signature are not yet checked.
The amount or signature does not match the order. We stop and alert a person.
Without it the transaction is not complete.
Verification passed. Only this status starts fulfilment.
A full or partial refund ordered from your panel, without signing in to the gateway. The refund status arrives in a separate notification.
Coming back to the site confirms nothing, so the page shows the payment in progress until the server verifies the transaction. The order changes status even if the customer closes the page.
