• Reduced development effort and time to market. 
• No need to handle sensitive BLIK codes on your servers. 
• PCI-compliant payment solution provided by us. 
• Customizable look and feel to match your brand using our Template builder. 
• Built-in handling payment status updates. Your customers see exact payment status updates in real-time and in natural language, to improve trust, transaction recovery and conversion rates. 

Integration Steps for Hosted Payment Page 

Create a Hosted Checkout 

When your customer proceeds to checkout, initiate a hosted checkout session by calling our API. Add the following properties to a standard CreateHostedCheckout request: 

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

Process flows

Depending on your customers' device(s) used, the checkout flow for BLIK is the same: 
With a desktop or a mobile device. 

1. Your customers finalise an order on their desktop or mobile browser in your shop and select BLIK as a payment method.
2. You send this CreateHostedCheckout request to our platform.
3. You redirect your customers on their desktop or mobile browser via the redirectUrl to our Hosted Checkout Page. Your customers type and enter the 6-digit BLIK code that is generated in their banking application.
4. Your customers confirms the payment in their banking application.
5. We receive the transaction result.
6. We redirect your customers to your redirectUrl on their desktop or mobile browser.
7. You request the transaction result from our platform via GetHostedCheckout or receive the result via webhooks.
8. If the transaction was successful, you can deliver the goods / service. 

Setting Up Webhooks for Payment Status Updates

For real-time updates on payment status changes, you should configure webhooks in your merchant account:

1. Log in to the Merchant Portal. 
2. Navigate to Configuration > Technical settings > Webhook configuration.
3. Configure a webhook endpoint URL that will receive payment status updates.
4. Select the events you want to receive notifications for (e.g., "PAYMENT_STATUS_CHANGED"). 
   Our platform will send webhook notifications to your endpoint whenever a payment status changes, allowing you to update your order status in real-time.
