Pay a Checkout Session

Processing a BLIK Payment

Notifications, often referred to as webhooks, provide a mechanism for applications to receive real-time updates about To process a BLIK payment, display BLIK as an available payment method on your system’s payment page. Include a dedicated field where the payer can enter their 6-digit BLIK code. Once the payer submits the form, verify if the response returns a 2XX status:events. Within this API, webhooks are used to inform your server about a range of events, including transactions, refunds, or card tokenization, allowing your system to react promptly to these occurrences.

• If the checkout session status is "open": Inform the payer that the system is waiting for payment confirmation. The payer will receive a push notification from their bank’s mobile app to confirm the payment. You will be notified of the transaction status through a webhook. Refer to the Checkout Session Webhook Events Specification section for more details.

• If the checkout session status is "completed": The payment has been successfully processed, and no waiting page is required.

Note:

BLIK transactions typically take 40 to 90 seconds to complete. If you do not receive a webhook notification within this time, prompt the customer to re-enter their BLIK code.
