Adds buyer ID support for BLIK payments


Adds buyer ID support for the related setting payments

What’s new

Adds the buyer_id property to the blik hash on the PaymentMethod object and to the payment_method_details.blik hash on the SetupAttempt object. The buyer_id property is a unique merchant-scoped identifier that helps identify the specific account holder making the payment.

The buyer_id property was previously available only on Charges.

Impact

You can now access buyer identification information for the related setting PaymentMethods and SetupAttempts through the buyer_id property. This additional data point can help you:

  • Implement sophisticated fraud detection rules
  • Meet compliance requirements for payment monitoring
  • Correlate payments from the same customer across multiple transactions and payment methods

The buyer_id property is read-only and populated automatically when provided by the related setting. No changes to your existing the related setting payment integration are required.
