BLIK

Intro

BLIK is the most popular mobile payment method in Poland for online payments. It enables e-commerce payments, POS payments (including contactless payments), ATM cash withdrawals, and mobile P2P payments.

BLIK is linked to a bank account rather than a physical card. With 90% of Polish bank customers having access to BLIK through their banking apps, it offers a broad reach and convenience.

To complete a payment with BLIK, customers generate a unique 6-digit code within their banking app and enter it at checkout. They then confirm the transaction in their app, ensuring seamless and secure authentication without third-party involvement.

Integrating BLIK is simple and requires only a few additional properties in the request. You can easily enable BLIK payments through Hosted Checkout Page solutions, plugins, or direct API integration.

{ 
	"order":{ 
		"amountOfMoney":{ 
			"currencyCode":"PLN", 
			"amount":1700 
		}, 
		"redirectPaymentMethodSpecificInput":{ 
			"paymentProductId":3204, 
			"requiresApproval":false 
		} 
	} 
}
