QR MIA – maib's system for generating, managing, and processing payments via QR codes (static, dynamic, hybrid), intended for merchants who want a fast, redirect-free solution for collecting payments.
QR Code – a code generated through the QR MIA API that contains the necessary information to initiate a payment. It can be Static, Dynamic, or Hybrid, depending on the context and purpose.
Static QR – a QR code containing only fixed data, without an amount or personalized details. Useful for repeated payments without a predefined value (e.g., donations).
Dynamic QR – a QR code generated for a specific purpose, used only once, and includes detailed transaction data (amount, customer, etc.).
Hybrid QR – a combination of static and dynamic. Can be used for both one-time and repeated payments.
qrId – the unique identifier of the generated QR, UUID type. Used as a reference in all API calls.
PayId – the unique identifier of the payment made under a QR. Returned in the payment response and used to track the transaction.
Sandbox – a secure testing environment where payments can be simulated without real funds. Intended for merchant app integration testing.
Production – the live environment where transactions are made with real funds, used by active merchants.
Executed (executedAt) – the moment when the payment was finalized. Returned in ISO 8601 format.
