BLIK

BLIK is a Polish mobile payment system. Buyers pay with a one-time code generated in their bank's mobile app, both online and in stores.

You can integrate and authorize BLIK payments in several ways. The basic authorization method is a BLIK code that the buyer generates in the bank's mobile app. BLIK payments can also be authorized with a UID token, which allows one-click payments on the shop's website. The authorization method depends on the integration scenario:

  • Redirecting to the BLIK payment page – After the buyer chooses BLIK and places the order, they are redirected to the BLIK payment page, enter the BLIK authorization code and confirm the payment in the bank's mobile app. This integration requires only standard pay-by-link handling.
  • Transparent payment with a BLIK authorization code – The buyer enters the BLIK authorization code on the shop's website and, after placing the order, confirms the payment in the bank's mobile app. Your website must support entering the BLIK authorization code. The buyer gets a simpler and more secure payment process without leaving the shop.
  • Transparent payment with the UID token – The buyer authorizes the payment with one click on the shop's website; confirmation in the bank's mobile app may not be required. This option requires a full implementation: token registration on your side, token payments and BLIK authorization code entry. As a result, buyers can pay both with one click and with a BLIK authorization code.
Note that...

UID token payments are not available by default. They require meeting certain requirements and completing a boarding process, so contact your PayU account manager before you start the integration.

Before you start the integration, review the BLIK OneClick requirements and guidelines.

All BLIK services except Redirecting to the BLIK payment page require a specific point of sale (POS) configuration by PayU. The configuration for Transparent payment with a BLIK authorization code and Transparent payment with the UID token is not compatible with Redirecting to the BLIK payment page, so these options require a separate POS.
