Please check the “expiryDate” in the Create a Code (POST /v2/codes) response field.
Since the time is set to a certain time after the request time, please check the response by actually trying Create a Code. The “fixed time” is subject to change for security reasons.
"expiryDate": The expiration time of the generated QR code itself.
For security reasons, this is set to a short period, and users must complete the scanning and payment within this time limit. The QR code becomes invalid and can no longer be scanned after a certain amount of time. Please note that this duration cannot be modified.
This is used when isAuthorization: true. As long as the user completes the scan and payment authorization within the expiryDate, the merchant can capture the payment at any time during the period set by authorizationExpiry (e.g., 15 minutes or 30 days). If merchants wish to change this duration, please set it in the authorizationExpiry field of the request body. (For details, please refer to the API documentation.)
