The APM Checkout (BLIK) integration allows customers to complete transactions using the BLIK payment method. This integration supports server-to-server (S2S) payments for Alternative Payment Methods (APMs) that involve a redirect flow. In this process, transaction details are securely exchanged between servers, and customers are redirected to a BLIK payment page to finalize the transaction, ensuring secure and efficient payment handling.
When customers select BLIK at checkout, the merchant creates a session with Converge Gate, providing necessary transaction details and customer information. Converge Gate generates a session ID and a redirect URL, which the customer uses to proceed with the payment.
Customer Pays with APM:
The customer initiates the payment by selecting APM (BLIK) as their payment method during the checkout process.
Merchant Creates a Session:
The merchant sends the transaction details and customer information to Converge Gate to create a checkout session.
Returns ID and Redirect URL:
Converge Gate processes the session creation request and returns a unique session ID along with a redirect URL.
Redirects to URL:
The customer is redirected to the provided URL (managed by APM) to proceed with the payment.
Receives Result from Bank via APM:
The APM communicates with the bank to process the transaction and receives the result, indicating whether the payment was successful or not.
Returns to the success_url:
Based on the transaction result, the customer is redirected back to the merchant's success URL if the payment was successful.
Retrieves Session ID & Updates Status:
The merchant retrieves the session ID from Converge Gate to check the transaction status and updates their records accordingly.
